Solution

The correct option is D Statement 1 is False, Statement 2 is True.
The atomic weights of sulphur and oxygen are $32$ and $16$ g/mol respectively. $1$ mole of sulphur dioxide $S O_{2}$ contains $32$ g sulphur and $32$ g oxygen. Thus, the mass ratio of sulfur and oxygen is $1 : 1$ .

Assertion :STATEMENT 1: SO2 obtained either by the oxidation of H2S or decomposition of sulphate salt contains sulphur and oxygen in the mass ratio 1:2. Reason: STATEMENT 2: S(s)+O2(g)→SO2(g).

The correct option is D Statement 1 is False, Statement 2 is True.The atomic weights of sulphur and oxygen are 32 and 16 g/mol respectively. 1mole of sulphur dioxide SO2 contains 32 g sulphur and 32 g oxygen. Thus, the mass ratio of sulfur and oxygen is 1:1.
