Question

if sulphur powder is burnt in air then initially gas X is dissolved in water a compound y is formed identify X and compound y also write a chemical reaction involved​

Answer 1

Explanation:

Sulfur is only mildly flammable under normal atmospheric conditions, but in pure oxygen, it burns with a very nice blue flame. The products of the combustion are sulfur dioxide and sulfur trioxide:

S(s) + O2(g) ——> SO2(g)

2S(s) + 3O2(g) ——> 2SO3(g)

These substances react with water in the air to produce sulfurous and sulfuric acid, respectively:

SO2(g) + H2O(g) ——> H2SO3(g) [sulfurous acid]

SO3(g) + H2O(g) ——> H2SO4(g) [sulfuric acid]
