What's the side effect of washing aluminum wire basin with detergent?!
Aluminum and oxygen reaction of aluminum in the air is easy to form a dense oxide, so the corrosion resistance of aluminum foil is very good. Can combustion in pure oxygen, namely 4Al+3O2 light - 2Al2O3.
Magnesium and oxygen reaction at room temperature: see magnesium was black, polished with sandpaper is silver white. Do magnesium combustion experiments, to note that the crucible clamp, below the mat of asbestos net. Magnesium is ignited, combustion, produce a dazzling light, the formation of white smoke, put a lot of heat; 2Mg+O2 light - 2MgO.
Iron and oxygen reaction under room temperature, iron dry air is difficult to react with oxygen. In the humid air, iron and oxygen slow oxidation generated rust (main component: Fe2O3; red rust, loose structure, easy to absorb water, accelerate the corrosion of iron and iron); after a slow oxidation after formation the compounds can also be considered in pure iron oxide, 4Fe+3O2=Fe2O3., wire can be ignited, combustion, Mars radiance, generating solid black, release a lot of heat (in the light before the first wire grinding, in the set of cylinders have a small amount of fine sand or water, to prevent the high temperature spatters burst bottom): 3Fe+2O2 - Fe3O4. light from the above experiment phenomenon, can be seen: "the same material under different reaction conditions, the phenomenon may be different, product may be different"
