Using the VSEPR theory and the diagrams above, -state and explain the geometries of the NH 4 + and NO 3 ions shown. 2. In Beirut we saw that there was already a fire burning for a significant amount of time before the explosion, as well as a smaller explosion that occurred < 30 seconds before the main one. Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Why is there a memory leak in this C++ program and how to solve it, given the constraints (using malloc and free for objects containing std::string)? Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. Suppose that each of the following pairs of aqueous solutions is combined. On the Thermal Decomposition of Ammonium Nitrate. Write a balanced equation for this reaction. These forms supply 50% of their N as pure nitrate and so instantaneously increase the quantity of nitrate in topsoil from a very low value, typically about 10kg nitrate-Nha1, to 50kg nitrate-Nha1 or more depending on the amount applied. The Pennsylvania State University. These aren't the only ways it can explode, but they are a few examples of the types of conditions that could lead to explosion. It is important to achieve an oxygen balance within the explosive. ANFO versus Emulsion Task 2 Decomposition or explosion? All the answers combined answers OP's question. Its simplicity of production and low cost, about $170/tonne in the U.S. in 1995, add to its product appeal. Combine about 5 mL each of 6 M sodium hydroxide and 6 M sulfuric acid in a large test tube. Webat ~23% ammonium nitrate decomposition; and at 230oC at 14%. This reaction isnt the only one taking place, however. High concentrations of nitrate in surface waters can lead to eutrophication (the sudden enrichment of natural waters with excess nutrients which can lead to the development of algal blooms and other vegetation). You will use 1 mL of solution in many of the reactions; estimate this by drops (typically 12-15 drops from the reagent bottle dispenser) or by measuring 1 mL once in your graduated cylinder and then transferring it to a test tube to determine how far it fills the test tube. The following reaction has been hypothesized as the main detonation reaction: 2NH 4 NO 3 2N 2 + O 2 + 4H 2 O. Scenario 1: Detonation from the top of the FGAN pile. Another source of dust is bagging and bulk loading, mostly during final filling when dust-laden air is displaced from bags. The ease with which a substance is oxidized is quantified as its standard oxidation potential; you will learn more about this in the second semester of General Chemistry. Production of Ammonium Nitrate and Urea in Selected Countriesa. Plants producing a solid ammonium nitrate product may employ all of the operations. The larger cations will increase the distance between clay particles, bond holding the particles together will be reduced, and result could be a dispersion of the particles. However, as discussed earlier in this chapter, the limiting factor with fine-textured soils is getting the effluent in contact with the surface area. Temperatures and Reaction Rate By George Feick and R. M. Hainer, Reaction Rates of Ammonium Nitrate in Detonation The very hot and contaminated surface of the pile was then sensitive to The retarding effect of reagent-grade hydrocarbons and the emulsion in the low temperature regime is quite obvious. Ammonia, \(\ce{NH3}\), is formed from the combination of ammonium and hydroxide ions: \[\ce{NH4Cl (aq) + NaOH (aq) -> NaCl (aq) + H2O (l) + NH3 (g)}\]. It decomposes at 230oC producing nitrous oxide gas (N 2 O) and water vapour. @JasonC There are many factors, not just heat. Heating also poses a danger: ammonium nitrate decomposes at around 230C, and can explode when heated to between 260300C if its confined. Large volumes of ammonium nitrate should be stored in a single story, dedicated, well-ventilated non-flammable structure. This fire further accelerated the reaction, further heating the remaining ammonium nitrate to the point of detonation and that's when ammonium nitrate exploded instantaneously releasing tremendous amount of energy which send shockwaves around the site along with a white mushroom shaped cloud (from @DDuck's comment) which could probably be nitrogen and/or water vapours where the humid air (water vapor laden air) condensed due to the explosion(@StianYttervik) with release of nitrogen. We use cookies to help provide and enhance our service and tailor content and ads. decomposition reactions of FGAN can only be assumed. Nitrates and nitrites are used to cure meats and to develop the characteristic flavor and pink color, to prevent rancidity, and to prevent growth of Clostridium botulinum spores in or on meats. (4 marks) Ques. By continuing you agree to the use of cookies. Thus, for the first case with a 92:8 ratio, we have: And for the second case, with a 96.6 : 3.4 ratio, we have: Lets look at the right-hand side of the equations. Ammonium nitrate is reactive and incompatible with several organic and inorganic compounds. Scenario 2: Detonation in heated FGAN along exterior wall exposed to fire. To write balanced equations for the reactions studied. Why or why not? From: Encyclopedia of Analytical Science (Second Edition), 2005, P.S. Use 1 mL of each solution unless otherwise specified. Fractured crystalline edges expose oxygen and hydroxyl groups that present a net negative charge. In the first reaction above, lead is more active than copper. WebN = 14.006 H = 1.0078 N = 14.006 C = 12.009 And then, we can calculate the molecular weight of the ammonium nitrate and the fuel oil. Te przydatne bindy CS GO Ci w tym pomog. What is the balanced equation for ammonium carbonate is heated, it decomposes into ammonia gas, carbon dioxide gas, and water vapor? You'll need to be patient balancing this equation! Are these explosions also detonations? Do not put metal strips in the sink. So, now we know that when we mix the ammonium nitrate with the fuel oil, we need to do it in this proportion if we want an oxygen balanced reaction. Displacement reactions are also classified as oxidation-reduction reactions. And from section 4.3, a few detonation scenarios: Based on the location of the pile and the properties of the bin along with the circumstances of other fire induced incidents, one possible scenario is that a period of contamination with soot and other organics Because it is an anion, nitrate is easily leached. The Journal of Physical Chemistry, Guy Marlair, Marie-Astrid Kordek, "Safety and security issues relating to low capacity storage of AN-based fertilizers,", Zhe Han, "Thermal Stability Studies of Ammonium Nitrate,", Alex M. Djerdjev, Pramith Priyananda, Jeff Gore, James K. Beattie, Chiara Neto, Brian S. Hawkett, "The mechanism of the spontaneous detonation of ammonium nitrate in reactive grounds,". Interestingly, ammonium nitrite ($\ce{NH4NO2}$) is far more labile and very hard to prepare as the two ions tend to react to form nitrogen gas and water even in solution at room temperature. Type of Chemical Reaction: For this reaction we have a decomposition reaction.Balancing Strategies: In this decomposition reaction, NH4NO3 is breaking apart (decomposing) into N2 + O2 + H2O. The determined percentage ammonium nitrate can be converted to %N by multiplying the percentage ammonium nitrate by 0.349978. Figure77. ScienceDirect is a registered trademark of Elsevier B.V.

Encyclopedia of Analytical Science (Second Edition), Encyclopedia of Toxicology (Third Edition), Environmental Inorganic Chemistry for Engineers, Waste Minimization and Cost Reduction for the Process Industries, Comprehensive Water Quality and Purification, Ammonia, Nitric Acid and Their Derivatives, Handbook of Chemical Technology and Pollution Control (Third Edition), Compiled from Statistics Canada, cat.no. However, the presence of organic and metallic impurities reduces this temperature. Possible sources of contamination in an Nitrate that leaches eventually enters ground and surface waters, where it may have potentially adverse environmental effects. At temperatures below around 300 C, the decomposition mainly produces nitrous oxide and water: NH 4 NO 3 N 2 O + 2H 2 O. For example, plants producing ammonium nitrate solutions alone use only the solution formation, solution blending and bulk shipping operations. Ammonium, nitrate, and phosphorus are plant-availabe nutrients that are found in wastewater and are frequently associated with excessive algae growth in surface waters. How much ammonium nitrate will be required for each gallon of fuel oil to make an oxygen-balanced batch of ANFO? the burning wood and other fuels. Write a balanced formula equation with state labels for each reaction. The Pennsylvania State University 2020, Module 1: Introduction to the Mining Industry, Module 2: The Life Cycle of a Mine and Related Matters, 6.2.1: Mixing ANFO and the Oxygen Balance, 6.2.3: Classification of Common Industrial Explosives, 6.2.5: Key Properties Affecting Choice of Explosives, Department of Energy and Mineral Engineering, Department of Materials Science and Engineering, Department of Meteorology and Atmospheric Science, Earth and Environmental Systems Institute, Earth and Mineral SciencesEnergy Institute, iMPS in Renewable Energy and Sustainability Policy Program Office, BA in Energy and Sustainability Policy Program Office, 2217 Earth and Engineering Sciences Building, University Park, Pennsylvania 16802. poor quality control at the batch mixing truck; incorrect formulation, for example by adding a sensitizer like aluminum, but not accounting for it in the addition of the fuel oil; improper timing of adjacent holes, allowing the explosive to become unconfined by the time it detonates; explosives at the collar of the hole (increases fume production, not fragmentation). Do you need to dry the test tubes before using them for the reactions in this experiment? If the blaster is using an 8-ounce container for the cup density check, what weight should be displayed on the scale? As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. If it is not displaced by other cations, it can be fixed to clay surfaces. (3 marks) Ques. This page titled 6: Types of Chemical Reactions (Experiment) is shared under a CC BY-NC license and was authored, remixed, and/or curated by Santa Monica College. Why we would we want to do that? bin, spilling FGAN into a mixture of burning rubber from the melted elevator belt and residual FGAN in Dalsze korzystanie ze strony oznacza, e zgadzasz si na ich uycie. and oxygen gas and water vapor. This reaction takes place at a temperature of over 300C. Record your observations on these data pages as you perform each reaction. The reactions that describe the decomposition of ammonium carbonate ((NH_4)_2CO_3) are: (NH_4)_2CO_3(s) -> NH_4HCO_(3(s)) + NH_(3(g)) (1) NH_4HCO_(3(s)) -> Ions of similar size (atomic radii) can substitute for the silicon ion in the tetrahedral layer and for the aluminum in the octahedral layer (Essington, 2004). It is a sad and quite devastating incident. They will compare that weight to the weight that they have been given as the specified weight. Some of it decomposes slowly creating toxic ________>________>________>________>________, most active (most easily oxidized) to least active. After balancing the Hydrogen atoms you'll find that you oxygen atoms are no longer balanced. What are the other chemical substances that are formed in the process of making ammonium nitrite? If decomposition happens at supersonic rates, this leads to a shockwave characteristic of a detonation. According to Ref.2, during the explosion, following exothermic reaction would take place (hydrocarbon is represented by $\ce{CH2}$): $$\ce{3NH4NO3 + CH2 -> 3N2 + 7 H2O + CO2} \quad \Delta H = \pu{-4017 kJ/kg} \tag1$$. What are the other chemical substances that are formed in the process of making ammonium nitrite? The oxygen is consumed by the fuel oil or a readily oxidizable metal such as aluminum or magnesium present to contribute further heat and power to the detonation process. Overall agronomic experiments show only small differences in crop utilization of N from urea compared with nitrate-containing fertilizers. Unless otherwise indicated dispose of all waste in the waste container provided. Mathew's answer below has some more reaction formulas with enthalpy changes and other info. \[\ce{Sn(s) + HCl(aq) -> H2(g) + SnCl2(aq)} \quad \quad \quad \text{______ >______}\], \[\ce{Au (s) + Sn(NO3)2 (aq) ->} \text{NR} \quad \quad \quad \quad \text{______ >______}\], \[\ce{Au(s) + HCl ->} \text{NR} \quad \quad\quad \quad \text{______ >______}\], \[\ce{Zn (s) + Sn(NO3)2 (aq) -> Zn(NO3)2 (aq) + Sn (s)} \quad \text{______ >______}\]. <> A metal that displaces hydrogen gas from acid is more active than hydrogen. This solution contains a swarm of ions a portion of which are cations trying to balance the surface charges. In this review data from the literature on thermal decomposition of ammonium nitrate (AN) and the effect of additives to their thermal decomposition are summarized. A fiberglass lid However, it is a strong oxidizing agent that can detonate under certain conditions such as temperature, fire, confinement, and presence of impurities (e.g., $\ce{KCl}$), which can be act as a promoter to detonate (Ref.2). In ammonium nitrate basically you have all you need - the "fuel and the oxygen analogues of what is involved in a standard, explosive or not, combustion. The second source of electronegativity is the isomorphous substitution of Mg2+ for Al3+ or Al3+ for Si4+. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); 2015-2022 Gametip.pl | Polityka Prywatnoci | Wsppraca. When the ammonium nitrate stores exploded, a white condensation cloud spread out in a sphere from the site, followed by a huge plume of red-orange smoke rising from the hanger. It will also explode more readily if contaminated or mixed with combustible materials such as fuel oil, the latter known as ANFO. It is very, very conceivable that the AN became both heated enough and contaminated enough during this time to detonate. They also further noted that beyond $\pu{280 ^\circ C}$, $\ce{NH4NO3}$ is capable of rapid, self-accelerating decomposition (to the point of detonation). If nitrate is a concern then, effluent application should be limited to the agronomic requirement of the plants in the soil absorption area, and then a large fraction of the plant biomass should be removed each year to prevent the organic nitrogen from being mineralized upon plant decomposition. Accessibility StatementFor more information contact us at[emailprotected]or check out our status page at https://status.libretexts.org. This means there is exactly enough oxygen present to completely oxidize the contained fuel, but none left over to react with the contained nitrogen. You should verify this result. This product is also known as laughing gas, and is used in dentistry for short term anaesthesia for extraction of molars, etc. Hazardous scenarios with ammonium nitrate can involve simple thermal decomposition initiated by external fire or other heating, self-sustained decomposition also known as "cigar burning," and detonation. For those where a reaction is expected, write a balanced formula equation, with state labels, for the reaction that occurs. WebWhen ammonium nitrite (NH4NO2) is heated, it decomposes to give nitrogen gas. A typical application of N to an arable crop in spring, at the beginning of the rapid crop growth period, might be 100200kgNha1, but usually divided into two or more portions. 2H 2(g) + O 2(g) 2H 2O(l) Decomposition Reactions occur when a compound breaks apart to yield two or more new substances. Thermodynamic properties of substances. Clay particles are the reactive portion of the soil; sand and silt comprise the soil skeleton. Most of these screening operations are enclosed or have partial covers to reduce emissions. From most active (most easily oxidized) to least active: Now use the above results to write products for the reactions below. please see my edited answer, also yes, an ANFO explosion would be even more powerful and easier to detonate, I guess one way of looking at things can be that ammonium nitrate decomposing into nitrous oxide and water in an endothermic fashion. The surface of the However, the presence of organic and metallic impurities reduces this temperature. Layers of silica tetrahedrons (silica atom with a four-sided oxygen configuration) and aluminum octahedron (aluminum atom within a six-sided oxygen or hydroxyl structure) are bound together by shared oxygen atoms. Clay particles usually have negative charges because of unsatisfied valences at the crystalline edges of the silica and alumina plates. gases like nitrogen oxides. Next, we should findthe weight ratio of ammonium nitrate to fuel oil. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. The gas, NO, changes to NO2 when exposed to the atmosphere. The solubility behavior of the ions that you will be using is summarized in the following table: Group IA and Ammonium compounds are soluble. The solubility of the substances. I attached PDF file if Ref.2 if a reader is interested in how explosions happen during right conditions (otherwise, it is a broad field to explain). It only takes a minute to sign up. The College of Earth and Mineral Sciences is committed to making its websites accessible to all users, and welcomes comments or suggestions on access improvements. When there are population centers nearby, it may be safer to store ammonium nitrate outside provided that it is sequestered from sources of heat, combustion, or hot work (operations involving open flames or producing heat and/or sparks, such as welding). With the dark smoke inside of the structure reduced, radiant heat The reactions that describe the decomposition of ammonium carbonate ((NH_4)_2CO_3) are: (NH_4)_2CO_3(s) -> NH_4HCO_(3(s)) + NH_(3(g)) (1) NH_4HCO_(3(s)) -> Potassium chlorate is one of the ingredients used in match heads. Not all of the combinations will yield observable reactions. WebPure ammonium nitrate does not explode easily and can be handled safely. A number of additives are available commercially that retard either urea hydrolysis or nitrification, so retaining a greater proportion of N from fertilizer in the ammonium form and decreasing the amount as nitrate. So, my theory is that ammonium nitrate started heating (from the fire) releasing all sorts of nitrogen oxides (the red fumes). Still $\ce{NH4^+}$ reduces $\ce{NO3^-}$ good enough, by itself. Walker, in Comprehensive Sampling and Sample Preparation, 2012, Derivatizing ammonium from ammonium nitrate with chloroformate results in a molecule that has more interaction with the column and therefore has a reasonable retention time of 6 min in the case of derivatizing with butyl chloroformate.18. releases huge amounts of energy.[]. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. This concentrated solution is further concentrated to obtain 9294% solution in a vacuum concentrator. NO2 is a toxic, but unlike CO, which is colorless, NO2 produces a bright yellow-orange cloud. Thus, in practice, the difference between urea and ammonium nitrate or CAN in terms of impact on soil nitrate is fairly small. drop pipe from the elevator mechanism) was followed by about 5 to 6 minutes of intense radiant heating 2NH 4 NO 3 2N 2 + 4H 2 O + O 2. In each case one of the products results by combining two ions that are removed from the solution by the reaction. The sulfuric acid can be titrated with sodium hydroxide to determine the amount of ammonium sulfate present. This reaction takes place at a temperature of over 300C. It's hard to imagine something worse than the explosion I saw in videos, but I wonder what the difference would have been if it were combined with fuel oil? This attraction of cations around clay particles gives rise to the ionic double layer. What are the physical properties of ammonium nitrite? Ammonium nitrate is composed of two polyatomic ions identify the different type(s) of bonding within its structure. [ Check the balance ] The thermal decomposition of ammonium nitrate to produce nitrogen, water and oxygen. It does decompose ENDOTHERMICALLY, so it's not self propagating, and is not a low explosive: As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. Mixtures of superphosphates and organic materials may ignite bulk quantities of ammonium nitrate if the internal temperature exceeds 90C. Type of Chemical Reaction: For this reaction we have a decomposition reaction. The percentage ammonium sulfate can be determined by the reaction of formaldehyde, which produces sulfuric acid. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. The ammonium is then nitrified within 23weeks. More powerful, or simply easier to detonate, or both? To use as an explosive or a blasting reagent, $\ce{NH4NO3}$ is mixed with fuel oil, which is called ammonium nitrate fuel-oil (ANFO; Ref.1). Komendy CS GO. When one thinks of fire and dissects the requirements of a fire into a fuel and an oxidiser, this is in chemical terms only a different way of determining an oxidising agent and a reducing agent in a redox reaction. Wszystko, co powiniene o nich wiedzie. 2. Connect and share knowledge within a single location that is structured and easy to search. Jumpthrow bind. Arrhenius plots for these ammonium nitrate composite systems were constructed. FGAN storage area can include ignitable liquids, finely divided metals or organic materials, chloride Why did the Soviets not shoot down US spy satellites during the Cold War? Web1. Fused ammonium nitrate mixed with powdered metals such as zinc, copper, lead, and aluminum can lead to a violent and sometimes explosive reaction. Another possible detonation scenario focuses on the elevator pit near the FGAN bin. Nitrate may be a limiting condition for determining the area needed for soil absorption. React these iron oxide, ammonium nitrate, and sucrose. WebThe chemical equation described in section 4.1 is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. As an example, potassium chlorate decomposes when heated to yield potassium chloride and oxygen gas. Please note that some reactions may be classified as more than one type of reaction; for example, combination and decomposition reactions that involve elemental substances are also oxidation-reduction reactions. For 3 moles of NH 4 NO 3 : 3*80.05 = 240.15 g, For 1 mole of CH 2: 1*14.03 = 14.03 g, The molecular weight of ANFO is, therefore: 240.15 + 14.03 = 254.18 g, NH 4 NO 3 : (240.15 / 254.18) *100 = 94.5% by weight, CH 2 : (14.03 / 254.18) * 100 = 5.5% by weight. Balancing Strategies: In this decomposition reaction, NH4NO3 is breaking apart (decomposing) into N2 + O2 + H2O. Solutions: 6 M \(\ce{HCl}\), 6 M \(\ce{NaOH}\), 6 M \(\ce{H2SO4}\), 1 M \(\ce{NH4NO3}\), and 0.1 M solutions of \(\ce{CuSO4}\), \(\ce{ZnSO4}\), \(\ce{AgNO3}\), \(\ce{NaCl}\), \(\ce{Ni(NO3)2}\), \(\ce{Pb(NO3)2}\), and \(\ce{K2CrO4}\), Equipment: crucible tongs, one large test tube, two small test tubes, ten small test tubes, test tube holder, test tube rack, 100-mL beaker, red litmus paper, Bunsen Burner Explosives applications have been varied from blends with nitroglycerin to make this safer for use in mines, to admixtures with smokeless powders and nitro compounds such as trinitrotoluene, to the more recent developments of blends of low-density ammonium nitrate prills with fuel oil (so-called ANFO explosives), or in water slurries with metal powder boosters to produce a low-cost heaving power explosive [58]. During this time, a layer of very hot, $$\ce {NH4NO3 -> [t >230 ^\circ C] N2O + 2H2O}$$ Repeat the reaction if there is any doubt about whether a reaction occurred or not. If the material is suddenly heated up, there will be explosive decompositions as shown in equations $(6)$ and $(7)$): $$\ce{2NH4NO3 -> 2N2 + O2 + 4H2O } \quad \Delta H = \pu{-1057 kJ/mol} \tag6$$ The number of operating steps employed depends on the specification of the product. Then write a balanced equation for each reaction. First, ammonium nitrate solution is prepared by reacting preheated ammonia with nitric acid in a neutralizer. The following reaction has been hypothesized as the main detonation reaction: 2NH 4 NO 3 2N 2 + O 2 + 4H 2 O. You should definitely read the report; my brief summary below leaves a lot of relevant analysis out. Once ammonium nitrate starts to decompose, a runaway reaction may occur as the heat of decomposition increases. N2O can be obtained by slow controlled decomposition. Explosions of ammonium nitrate fertilizer in storage or transportation are preventable accidents, Review on thermal decomposition of ammonium nitrate. WebAs ammonium nitrate is a salt, both the cation, NH 4+, and the anion, NO 3, may take part in chemical reactions. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. For reactions involving metals, use just one piece of metal. The external surface area of 1g of colloidal clay is at least 1000 times that of 1g of coarse sand. WebAmmonium nitrate melts at 337 deg F (170 deg C) and begins to undergo decomposition when molten. G.S. Monovalent ions such as sodium and potassium have a larger effective radius and can be exchanged for the smaller divalent cations. 1 M ammonium nitrate and 6 M sodium hydroxide. Solid ammonium nitrate decomposes on heating. This paper 1 notes that the irreversible decomposition of ammonium nitrate occurs at the temperature range of $\pu {230-260 ^\circ C}$. The term prill is also used in manufacturing to refer to a product that has been pelletized. \[\ce{3 CaCl2 (aq) + 2 Na3PO4 (aq) -> Ca3(PO4)2 (s) + 6 NaCl (aq)}\]. Removal of nitrate from the soil by leaching has several consequences. Note: Method 1 is of less importance now and used less because formaldehyde can be a safety hazard if not used properly. It's these gases that are responsible for might have melted the cover, and FGAN remnants could have been in the pit. Observe. Rao, in Encyclopedia of Toxicology (Third Edition), 2014. When contaminants are added to AN, the Duress at instant speed in response to Counterspell. Additives such as magnesium nitrate or magnesium oxide may be introduced into the melt prior to solidification to raise the crystalline transition temperature, act as a desiccant (removing water) or lower the temperature of solidification. This dust is usually captured and recycled to coating storage. Its not the only additional product: ammonia and nitrous oxide are amongst the others. Dissolved cations form an outer layer around the clay surface (Hiemenz, 1986). A metal that displaces hydrogen gas from acid, but not from water, is less active than one that can displace hydrogen from both acids and water. It is classified as an oxidizer and will accelerate burning when involved in a fire. the bottom of the pit. used up and exploded. The foaming FGAN likely The hot granules are dried in a rotary drier by hot air, screened and cooled in coolers to obtain the product. Komenda na legalnego aimbota CS:GO. Jak zwikszy FPS W CS GO? detonation began in the pit, then the most feasible mechanism would be a collapse of the west wall of the Although you know the weight of each ingredient in the mix, you dont know the density of the mix. You explained the contamination part, Jan explained the instability of AN. It is known that ammonium nitrate decompose exothermically when heated to form nitrous oxide and water. Side note: ammonium nitrate can decompose by mechanical shock, so there were enough conditions to trigger the second powerful blast. ammonium nitrate is a kind of mixture between an oxidizer - the nitrate part - and a reducer - the ammonium one.
