Answer 2

The chemical reaction you've written is a redox reaction between copper (Cu) and nitric acid (HNO3). In this reaction, copper reacts with nitric acid to produce copper nitrate (Cu(NO3)2), nitric oxide (NO), and water (H2O).

Here's the balanced chemical equation for the reaction:

3Cu + 8HNO3 → 3Cu(NO3)2 + 2NO + 4H2O

In this equation:

• 3 moles of copper (Cu) react with
• 8 moles of nitric acid (HNO3) to produce
• 3 moles of copper nitrate (Cu(NO3)2),
• 2 moles of nitric oxide (NO), and
• 4 moles of water (H2O).

Please note that this reaction typically occurs under specific conditions, and the products and their quantities may vary depending on factors like the concentration and temperature of the reactants. Additionally, nitric acid is a strong oxidizing agent, and the reaction can be quite exothermic and potentially hazardous, so it should be conducted with care in a controlled laboratory environment.
