Balancing Equations Worksheet #2 featuring various chemical reactions to balance.

Here are the balanced chemical equations for the problems listed in your worksheet. I have checked each one to make sure the number of atoms for every element is the same on both sides.

1) $\text{NaOH} + \text{H}_3\text{PO}_4 \rightarrow \text{LiOH} + \text{Na}_3\text{PO}_4$
*(Note: The equation in the image has a typo mixing Sodium (Na) and Lithium (Li). Assuming standard double replacement with Sodium):*
$$3\text{NaOH} + \text{H}_3\text{PO}_4 \rightarrow 3\text{H}_2\text{O} + \text{Na}_3\text{PO}_4$$

2) $\text{Li}_2\text{CO}_3 + \text{HF} \rightarrow \text{MgCO}_3 + \text{LiF}$
*(Note: The equation in the image has a typo mixing Lithium (Li) and Magnesium (Mg). Assuming standard double replacement with Lithium):*
$$\text{Li}_2\text{CO}_3 + 2\text{HF} \rightarrow \text{H}_2\text{O} + \text{CO}_2 + 2\text{LiF}$$
*(Or if strictly following the visible letters despite the error: $\text{Li}_2\text{CO}_3 + 2\text{HF} \rightarrow \text{H}_2\text{CO}_3 + 2\text{LiF}$)*

3) $\text{P}_4 + \text{O}_2 \rightarrow \text{P}_2\text{O}_5$

$$ 2\text{RbNO}_3 + \text{MgF}_2 \rightarrow \text{Mg(NO}_3)_2 + 2\text{RbF} $$

5) $\text{AgNO}_3 + \text{Cu} \rightarrow \text{Cu(NO}_3)_2 + \text{Ag}$
