The next piece of video showing the burning of sodium in oxygen describes the oxides formed as "hygroscopic". However chromium oxide is more stable and it doesn’t reduce. This can increase the potential for a combustion event and add challenges to mitigating strategies. On burning metals react with oxygen to produce-a. The alkali metals react with oxygen to form several different compounds: suboxides, oxides, peroxides, superoxides, and ozonides. Oxides tend to be solids or gases. Do the oxides of metals behave differently in water than those of non-metals? Alkali metal oxides result from the oxidation-reduction reactions created by heating nitrates or hydroxides with the metals. When a metal reacts with oxygen, a metal oxide forms. With the exception of mercury(II) oxide, it is possible to produce the oxides of the metals of groups 2–15 by burning the corresponding metal in air. If it is exposed to the air, it forms a white oxide layer very quickly. Commercially, nitric oxide is produced by burning ammonia (NH 3), whereas in the laboratory it can be produced by the reduction of dilute nitric acid (HNO 3) with, for example, copper (Cu). On the whole, the metals burn in oxygen to form a simple metal oxide. 1. Calcination: Heating of carbonate ores in the limited supply of air to convert them into oxides is known as CALCINATION.
