Although the molecular mass of H2S is more than that of H2O, H2O is a liquid, whereas H2S is a gas. Justify the statement.

2 H2S + 3 O2 → 2 H2O + 2 SO2. The reaction is exothermic, so quite a lot of heat is generated. NOTE: Hydrogen sulphide is very toxic so please don’t prepare it at home. Its toxicity is comparable to carbon monoxide. (Only 5mins exposure to 800ppm H2S in air is a lethal concentration for 50% of humans.)
