Chemical and War By 周骥 Because of the wars, many weapons have been invented in the human years. And as we know the chemical is very important for the weapons and wars. War with cold weapons C+O2=CO2 CO2+C=2CO XO+CO=X+CO2 (X is metal chemical element) Metal weapons need metal smelting technology. War with gunpowder weapons Gunpowder is one of the four great inventions of China. About every 4g black powder burning, can produce 280L gas volume expandable nearly ten thousand times. S + 2KNO3 + 3C == K2S + N2↑+ 3CO2↑ Black powder burning is called “one sulfur two nitrate three charcoal” and it means the scale of sulfur, nitrate and charcoal. When black powder burning: Trinitrotoluene三硝基甲苯(TNT) Ball-and-stick model structural formula Smoke Shell 烟雾弹 White phosphorus Smoke Shell: 4P+5O2=2P2O5 P2O5+H2O=2HPO3 P2O5+3H2O=2H3PO4 SiCl4+4H2O=H4SiO4+4HCl SnCl4+4H2O=Sn(OH)4+4HCl War with chemical weapons mustard gas 芥子气 ClCH=CHAsCl2 珍爱和平 远离战争 That’s all thanks * *
