Here are the balanced chemical equations for each problem on the worksheet.

1. $2\text{H}_2 + \text{O}_2 \rightarrow 2\text{H}_2\text{O}$

2. $\text{H}_3\text{PO}_4 + 3\text{KOH} \rightarrow \text{K}_3\text{PO}_4 + 3\text{H}_2\text{O}$

3. $6\text{K} + \text{B}_2\text{O}_3 \rightarrow 3\text{K}_2\text{O} + 2\text{B}$

4. $\text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H}_2\text{O}$
*(This one is already balanced)*
