a)Hydrogen Sulphide gas burns in air to give water and sulphur di oxide.
b)Aluminium metal reacts with steam to give aluminium hydroxide and hydrogen gas.
​

Answer 1

Answer:

1) H2S + O2 gives H2O + SO2

2) Al + H2O(steam) gives Al(OH)2 + H2

Answer 2

and (b) Al + H2O(steam) → Al(OH)3 + H2

Balanced: Al + 3H2O(steam) → Al(OH)3 + 3H2
