化学方程式 反应现象 应用（Chemical equation, reaction phenomenon, application） Chemical equation, reaction phenomenon, application 2Mg+O2 ignite or ignite strongly at 2MgO. Dazzling white light. Producing white solid. Exothermic. Produces a large white smoke flare 2Hg+O2 2HgO, a silver light or liquid form red solid Lavoisier experiment 2Cu+O2 ignite or delta 2CuO red metal into black solid 4Al+3O2 or 2Al2O3 light silvery white metal into a white solid 3Fe+2O2 ignites Fe3O4, burns violently, Mars is radiant, producing black solids, exothermic 4Fe + 3O2, high temperature 2Fe2O3 C+O2 ignites CO2, burning violently, white light, releasing heat, and making lime water muddy S+O2 ignites SO2, burns violently, releases heat, stimulates the smell of gas, and burns light blue flames in the air. Blue and purple flames in oxygen 2H2+O2 2H2O blue flame lit, exothermic, generated anhydrous CuSO4 blue liquid (water) high energy fuel 4P+5O2 ignites 2P2O5, burns violently, produces large amounts of white smoke, releases heat, and produces white solids, demonstrating oxygen levels in the air CH4+2O2 ignites 2H2O+CO2 blue flames, exothermic, and generates liquid (water) methane that makes lime water turbid, gas and blue water, and the combustion of natural gas in CuSO4 2C2H2+5O2 2H2O+4CO2 light blue flame, heat release, black smoke, makes the limewater turbid gas and the anhydrous CuSO4 blue liquid (water), oxyacetylene flame welding and cutting metal 2KClO3MnO2 +3O2 = Delta 2KCl generated with Mars, wood rekindled laboratory preparation of oxygen gas 2KMnO4 K2MnO4+MnO2+O2 = purple generated glowing splint rekindled laboratory preparation of oxygen gas, black 2HgO Delta 2Hg+O2 = red generation gas Lavoisier experiment with Mars resurgence is silvery white, wood 2H2O power 2H2 = +O2 = water power decomposition into hydrogen and oxygen in water electrolysis Cu2 (OH) 2CO3 2CuO+H2O+CO2 green arrow, black tube wall, the liquid limewater turbid gas heating P. NH4HCO3 NH3 = H2O +CO2 = a + white solid l
