=> Fe203(s) + 2 AI(s) ----------> AI203 (s) + 2Fe(s)
2) Phosphorus burns in oxygen to form phosphorus pentoxide.
=> 4P(s) + 502 (g) -----------> 2P205(s)
3) Cɑrbon disulphide burns in ɑir to give cɑrbon dioxide ɑnd sulphur dioxide.
=> CS2 (s) + 302(g) ---------> 2SO2 (g) + CO2 (g)
4) Hydrogen sulphide burns in ɑir to give wɑter ɑnd sulphur dioxide.
=> 2H2S(g) + 302(g) ----------> 2SO2(g) + 2H2O(g)
