Why `H_2O` molecules remain associated in the liquid form ?

If molecular interaction between two different liquid molecules are stronger than the molecular interactions between the pure liquid molecules, the mixture is expected to show:

Comment on the nature of two S-O bonds formed in SO_2 molecule. Are the two bonds in this molecule equal?

Why are liquids and gases categorised as fluids?

Why is H_2O liquid and H_2S a gas ?

In gaseous reactions important for-the understanding of the upper atmosphere H_2O and O react bimolecularly to form two OH radicals. DeltaH for this reaction is 72 kJ at 500 K and E_a is 77 kJ mol^-1 , then E_b for the bimolecular recombination of two OH radicals to form H_2O and O is::
