1) Si - Silicon dioxide is formed when silicon reacts with oxygen. Silicon dioxide further reacts to form orthosilicic acid, which then forms potassium silicate
2) N₂ - Nitrogen reacts with oxygen to form NO, which then forms nitrous acid. Nitrous acid further reacts to form ammonium nitrate
3) C - Carbon reacts with oxygen to form carbon dioxide, which then reacts to form calcium carbonate. Calcium carbonate further reacts to form calcium bicarbonate
4) Silicon dioxide reacts to form potassium silicate
5) Nitrogen reacts to form hydrazoic acid
6) Carbon reacts to form aluminum carbide
7) Carbon dioxide reacts to form sodium carbonate
8) Carbon dioxide reacts to form calcium bicarbonate.
