CO2, N2, H2S, and SO2 were probably present in Earth's early atmosphere. d. volcanic eruptions may have released CO2, N2, H2S, and SO2 into Earth's early atmosphere. e. ice has been found in meteorites and on ... Both H2S and SO2 are gaseous compounds at room temperature. The key difference between H2S and SO2 is that H2S has the smell of a rotten egg, whereas SO2 has the smell of a burnt match. Therefore, both these gases have a pungent odour. Besides, we can produce H2S via the separation of sour gas while … See more H2S is hydrogen sulfide. It is a gas at room temperature, having the smell of a rotten egg. Therefore, it has a pungent and irritating odour. … See more SO2 is sulfur dioxide.
