# In the reaction 2Li(s) + 2H_2O(l) -> 2LiOH(aq) + H_2(g), what compound is in the liquid state?

Mar 8, 2016

${H}_{2} O$

#### Explanation:

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

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