Phosphorus burns in oxygen to give phosphorus penataoxide.
APPROPRIATE ANSWER REQUIRED.....

Answer 1

1)   phosphorous burns in oxygen to give phosphorous pentoxide.
4P(s) + 5O2 (g)------>  2P2O5(s)
2) Carbon disulphide burns in air to give carbon dioxide and sulphur dioxide:
CS2 (s) +  3O2(g) -------> 2SO2 (g)+ CO2(g)
3)Hydrogen sulphide gas burns in air to give H2O and Sulphur dioxide:
2H2S(g)  +  3O2(g) ---------->    2SO2(g) + 2H2O(g)
4)Aluminium metal replaces iron from ferric oxide giving aluminium oxide and iron:
Fe2O3(s) + 2 Al(s)  ---------->   Al2O3 (s) +  2Fe(s)

Answer 2

P + 5O = 2P O
