Account for the following: `CO_2` is linear but `SO_2` is angular.

Account for the following:- NO_2 dimerises to N_2O_4 .

Account for the following: H_2O_2 is a bleaching agent.

Account for the following:- H_2O is a liquid while H_2S Is a gas.

Give reasons for the following: CO_2 is a gas whereas SiO_2 is a solid.
