Answer

1

Explanation

It is a colourless gas.It is an extremely poisonous substance (a slittle as`1` part per `1000` parts of air is fatal),but fortunately its smell becomes introerable long before the total concentration is reached.
Unlike water `H_(2)S` is a gas,since the electronegativity of the`S` atom is insufficient to allow it to participate in intermolecular hydrogen bonding. However,its molecules like `H_(2)O` is angular with two lone pairs and two bonding pairs.
