HNO3+NaOH=? Na2Co3+HNO3=?

For the reactions you've provided, we can determine the products by considering the reactants involved.

1. HNO3 + NaOH:

This is an acid-base neutralization reaction. Nitric acid (HNO3) reacts with sodium hydroxide (NaOH) to produce sodium nitrate (NaNO3) and water (H2O).

Balanced Reaction: \[ \text{HNO}_3 + \text{NaOH} \rightarrow \text{NaNO}_3 + \text{H}_2\text{O} \]

2. Na2CO3 + HNO3:

This reaction involves sodium carbonate (Na2CO3) reacting with nitric acid (HNO3). The products of this reaction will be sodium nitrate (NaNO3), water (H2O), and carbon dioxide (CO2). Carbonate reacts with acids to produce carbon dioxide.

Balanced Reaction: \[ \text{Na}_2\text{CO}_3 + 2\text{HNO}_3 \rightarrow 2\text{NaNO}_3 + \text{H}_2\text{O} + \text{CO}_2 \]

In summary:

• \( \text{HNO}_3 + \text{NaOH} \rightarrow \text{NaNO}_3 + \text{H}_2\text{O} \)
• \( \text{Na}_2\text{CO}_3 + 2\text{HNO}_3 \rightarrow 2\text{NaNO}_3 + \text{H}_2\text{O} + \text{CO}_2 \)
