Write out the balanced equation for the following word equation. Use the proper state abbreviations for each of the reactants and products as well:

Lithium metal reacts with liquid water to form hydrogen gas and aqueous lithium hydroxide.

Li (s) + H₂O (l) → 1/2 H₂ (g) + LiOH (aq)

Explanation:

Lithium metal reacts with liquid water to form hydrogen gas and aqueous lithium hydroxide

2Li (s) + 2H₂O (l) → H₂ (g) + 2LiOH (aq)

We can divide stoichiometry coefficients / 2, to have the lowest stoichiometry.
