H_2O

Explanation:

The letters between brackets by the compounds represent their state of matter:

(s) means it's something solid
(l) means it's something liquid
(aq) means it's something aqueous, that is, something that's either dissolved or can only exist in solution like an ion.
(g) means it's a gas.

Since the equation given already has those to see which one is liquid you just need to check the letters.
