Question

Zn+HNO3стрелкаZN(NO3)2+NO+H2O​

Answer 1

Ответ:

3Zn + 8HNO₃ → 3Zn(NO₃)₂ + 2NO + 4H₂O

Answer 2

The chemical equation you provided represents the reaction between zinc (Zn) and nitric acid (HNO₃) to form zinc nitrate (Zn(NO₃)₂), nitric oxide gas (NO), and water (H₂O). This is a redox reaction where zinc is oxidized and nitric acid is reduced.

The balanced chemical equation for this reaction is:

$\text{Zn} + 2\text{HNO}_3 \rightarrow \text{Zn(NO}_3\text{)}_2 + \text{NO} + \text{H}_2\text{O}$

In this balanced equation:

• 1 molecule of zinc (Zn) reacts with 2 molecules of nitric acid (HNO₃) to produce 1 molecule of zinc nitrate $(\text{Zn(NO}_3\text{)}_2)$, 1 molecule of nitric oxide gas (NO), and 1 molecule of water $(\text{H}_2\text{O})$.
