Rare haze holiday, the school left a 40 papers, a total of only five days to rest ah Hey. . .

Well, first put the papers aside. Tonight I did a test in accordance with feeling. Calculation of the theoretical amount was 0.5mol magnesium powder with 1mol ammonium nitrate, and then the actual mix of ammonium nitrate when I feel bad, so it only took 0.2mol, results. . . Look experimental phenomena like ammonium nitrate overdose doubled. So, I think this reaction is certainly not a simple displacement reaction, but relatively few complex chain reaction a little. The following is my guess.

When mixing the ammonium nitrate and magnesium I smell strong ammonia smell, so that it was still a displacement reaction can occur at room temperature, but the intermediate barrier magnesium nitrate and magnesium nitrate in the middle, thereby preventing They I when mixed reaction. Whereby the main reaction is a substitution reaction excluded. The following reasons. (All of the following has not been confirmed that some No theoretical support)

Assumed that the electronic firing head is sufficiently high temperature (603K, about 330 ) can be generated such that thermal decomposition of magnesium nitrate, magnesium oxide and nitrogen dioxide, and the generated oxygen, but this time the ignition temperature of magnesium is insufficient oxygen in the combustion (magnesium flash point 500 ), so the rest of magnesium oxide or prevent further reaction. Meanwhile, a temperature of 330 will cause thermal decomposition of ammonium nitrate, ammonium nitrate decomposition as different products at different temperatures, and the reaction is exothermic, so the product was as follows: nitrous oxide, water, nitrogen, oxygen , nitric acid molecule. Wherein the nitrous oxide with water molecules to form nitric acid and the reaction may be nitrogen.

The reaction carried out here I did not measure temperature, but following the experimental video, show their excess ammonium nitrate decomposition and light emission temperature sufficient magnesium powder, magnesium powder presumably generated with the reactive oxygen and nitrogen reaction. Also at 500 nitric acid molecules should have been decomposed into nitrogen dioxide and oxygen as well as water, which, I guess the reaction should not be so high temperature of several thousand degrees Celsius to decompose water into hydrogen and oxygen, so it is assumed that water and nitrogen dioxide and magnesium does not participate in light emitting reactions. And nitrous oxide at high temperatures can be similarly decomposed into nitrogen and oxygen. The final product should be magnesium oxide and magnesium nitride. And magnesium nitride, and wherein the above water reaction to produce ammonia and magnesium hydroxide, magnesium hydroxide decentralized heat water molecules in the case of magnesium oxide becomes, if ammonia is decomposed into nitrogen and hydrogen will to a certain extent. Hydrogen should be burned or released into the atmosphere, but for the experiment almost no impact. The final nitrogen while participating in the above reaction.

After the above process so that the final product should be obtained magnesium oxide, nitrogen, water, ammonia, oxygen, and nitrogen oxides.

Again, the above process is purely delusional, not confirmed, probably can be explained by the reaction of magnesium powder and ammonium nitrate, and confirm the displacement reaction is not the primary reaction. If you can find some detailed information to support academic or modify my guess, the next grateful. Get yourself a few pictures:

simply a mess, I think this explanation is not true, there are many, there are problem areas, so please help us to pause and ponder, to the comments section leave a message or something, thank you.

Well, there is no clear reaction principle, had to try the violence, according to the slow release video of the experiment, the reaction process 70 seconds, nearly 20 seconds is the decomposition of ammonium nitrate, ammonium nitrate so I think the amount should be reduced to one-third one-half, that is, 0.5mol magnesium ammonium nitrate with 0.1 to 0.15mol, but I think it may be more appropriate 0.75mol ammonium nitrate, ammonium nitrate because I'm running out of 2333

Finally, the last, Zhang put it M84-like structure diagram, Figure source US Army, the US federal government's copyright, the authorization unofficial translation is my own. I refused to check the water meter transnational and multinational warmth, nor multinational courier 2333

Well, so be it. I always feel at home there are always special effort to do these experiments, or very tired. Tools and reagents are not full, you want to have a quality called a balance, and if a school laboratory, then do not feel bad what's what thermometer to measure the heat of reaction directly on hate violence. But after all, their home, and there is no suitable testing ground, land mine so do it now before it's almost perfect figure by 2333 not in order to restore M84, grains are packed in aluminum inside, the outside is made of steel perforated shells, from which the sound and light shone through, and I have not seen this stuff in action, the sound is how you do it, I do not know (initially concluded that the reaction produced gas to break up the aluminum, or other chemical reactions ). So I feel this is harder than smoke bombs and more.

Speaking of another smoke bomb, I found half a bottle of potassium nitrate from the depths of my bookcase, so be it can make smoke bombs solid 2333 but the smoke can not be ignited electronic firing head is also a problem.

The report right here. What do you think of the idea you can also leave any comments. Yep.

Comments from:

Ammonium nitrate to fine grinding, fried dry. Magnesium powder mainly provides temperature and flash, ammonium nitrate oxygen can be restored. After the high temperature decomposition of ammonium nitrate explosive directly, generate a large amount of gas generated sound, it does not require much explosive reducing agent, so to excess ammonium nitrate.
