Question

Cu + HNO₂ → Cu(NO3)2 + NO ₂ + H₂O

Answer 1

Объяснение:

Cu + 4HNO3→ Cu(NO3)2 + 2NO ₂ + 2H₂O

Answer 2

The equation you provided is a balanced chemical equation representing the reaction between copper (Cu) and nitrous acid (HNO₂):

Cu + HNO₂ → Cu(NO₃)₂ + NO + H₂O

In this reaction, copper reacts with nitrous acid to form copper(II) nitrate (Cu(NO₃)₂), nitric oxide (NO), and water (H₂O).

It's important to note that this reaction requires the appropriate stoichiometric coefficients to be balanced correctly. These coefficients indicate the relative amounts of each substance involved in the reaction. However, without the coefficients, it is not possible to determine the balanced equation. Could you provide the coefficients for each species involved in the reaction?
