Question

5) Cu(NO3)2 --> Cu → SO2 →Ca(HSO3)2​

Answer 1

Ответ:

Cu(NO₃)₂ + Fe = Cu + Fe(NO₃)₂

Cu + 2H₂SO₄(конц.) = CuSO₄ + SO₂↑ + 2H₂O

2SO₂ + Ca(OH)₂ = Ca(HSO₃)₂

Answer 2

The chemical reaction you've provided is not balanced, and it seems to be missing some important information. To balance the equation and provide a meaningful reaction, I'll need more details, such as reactants, products, and conditions.

Cu(NO3)2 typically decomposes when heated to form copper oxide (CuO) and nitrogen dioxide (NO2) gas. The balanced equation for this reaction is:

2 Cu(NO3)2(s) → 2 CuO(s) + 4 NO2(g) + O2(g)

However, you mentioned "SO2" and "Ca(HSO3)2," which are not part of this reaction. If you have a different reaction in mind or if you could provide more information, I'd be happy to help you further.
