1.	H_(2)S and NH_(3) gas evolved at same time form factory of cylinder than which gas can expand fast ?
Answer» Solution :`NH_(3)` gas can expand FAST because its MOLECULAR mass is 17 gm/mol and molecular mass of `H_(2)S` gas is 34 gm/mol so density of `NH_(3)` is less than `H_(2)S`. So `NH_(3)` gas expand fast than `H_(2)S`.
