#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.
