Question

Сu(OH)2-CuO-Cu(NO3)2

Answer 1

Cu(OH)2=t=>CuO+H2O
CuO+2HNO3=>Cu(NO3)2+H2O

Answer 2

Cu(OH)2 (copper hydroxide) can be thermally decomposed to form CuO (copper oxide) and water. This reaction can be represented as:

Cu(OH)2 → CuO + H2O

CuO (copper oxide) is a black solid that can react with nitric acid (HNO3) to form copper nitrate (Cu(NO3)2) and water. The balanced chemical equation for this reaction is:

CuO + 2HNO3 → Cu(NO3)2 + H2O

So, the overall reaction from Cu(OH)2 to Cu(NO3)2 is:

Cu(OH)2 → CuO + H2O CuO + 2HNO3 → Cu(NO3)2 + H2O

In summary, Cu(OH)2 can be converted to Cu(NO3)2 through the intermediate formation of CuO.
