Question

The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below.

Ba(NO3)2 + 2LiOH → Ba(OH)2 + 2LiNO3

How many nitrate ions are in the products and the reactants of the chemical equation?

Answers

In the provided chemical equation:

\[ \text{Ba(NO}_3\text{)}_2 + 2\text{LiOH} \rightarrow \text{Ba(OH)}_2 + 2\text{LiNO}_3 \]

we can count the number of nitrate ions (NO3⁻) in both reactants and products.

1. **In the Reactants**:
- \( \text{Ba(NO}_3\text{)}_2 \) has 2 nitrate ions.
- \( 2\text{LiOH} \) does not contain any nitrate ions.
- Therefore, the total number of nitrate ions in the reactants is 2.

2. **In the Products**:
- \( \text{Ba(OH)}_2 \) does not contain any nitrate ions.
- \( 2\text{LiNO}_3 \) has 2 nitrate ions (one from each \( \text{LiNO}_3 \)).
- Therefore, the total number of nitrate ions in the products is also 2.

In summary, there are **2 nitrate ions in the reactants** and **2 nitrate ions in the products** of the chemical equation.
