At room temperature `H_(2)O` is a liquid while `H_(2)S` is a gas. Explain.

Why is H_(2)O a liquid while H_(2)S is a gas ?

HF is a liquid while HCl is a gas - explain.

H_(2)O is neutral while H_(2)S is acidic - explain.

Why is H_(2)O a liquid and H_(2)S a gas ?

(A) H_(2) O is a liquid while H _(2) S is gas at room temperature (R ) Both H_(2)O and H_(2)S are exothermic compounds

SiO_(2) is solid while CO_(2) is a gas at ordinary temperature. Explain.

Oxygen is more electronegative than sulphur, yet H_(2)S is acidic while H_(2)O is neutral. This is because

(A) SO_(2) gas is easily liquified while H_(2) is difficult to liquify . (R ) SO_(2) has low critical temperature while H_(2) has high critical temperature.

Although both CO_(2) and H_(2)O are triatomic molecules, the shaep of H_(2)O molecule is bent while that of CO_(2) is linear. Explain this on the basis of dipple moment?

H_(2) gas is liberated when H_(2)O_(2) reacts with
