Question

A number of reactions can be used to generate common gases on a laboratory scale. For example, nitrogen can be produced from sodium metal and potassium nitrate as indicated by the balanced equation:

10Na(s)+2KNO3​(s)K2​O(s)+5Na2​O(s)+N2​(g)

A common laboratory-scale reaction can also generate oxygen gas by heating potassium chlorate, as indicated by the balanced equation:

2KClO3​(s)2KCl(s)+3O2​(g)
