Question

solid lithium oxide reacts with liquid water to form aqueous lithium hydroxide. express your answer as a chemical equation including phases. a chemical reaction does not occur for this question.

Explanation:

Step1: Write unbalanced equation

$\text{Li}_2\text{O}(s) + \text{H}_2\text{O}(l)
ightarrow \text{LiOH}(aq)$

Step2: Balance Li atoms

$\text{Li}_2\text{O}(s) + \text{H}_2\text{O}(l)
ightarrow 2\text{LiOH}(aq)$

Step3: Check other atoms (H, O)

H: 2 on left, 2 on right; O:2 on left,2 on right. Balanced.

Answer:

$\text{Li}_2\text{O}(s) + \text{H}_2\text{O}(l) = 2\text{LiOH}(aq)$
