Question

What happens if
1) copper nitrate undergoes heating
2)Iron sulphate reacts with zinc metal

Answer 1

Hye mate..

1] Copper nitrate is a bright blue crystalline solid containing three molecules of water. When it is heated first it loses the water molecule, on further heating it decomposes to give reddish brown gas, nitrogen dioxide and oxygen. Chemically,

▪2Cu(NO3)2 -----Δ---> 2CuO + 4NO2 + O2

2] Zinc is a more reactive metal than iron. As a result, When Zinc is reacted with Iron Sulphate , Zinc will replace Iron Sulphate from its solution and will form Zinc Sulphate. Chemically ,

▪Zn + FeSO4 ----> ZnSO4 + Fe

Hope it helps !!

Answer 2

When copper nitrate undergoes heating
Cu(NO3)2.3H2O---heat--- Cu(NO3)2 +3H2O
2Cu(NO3)2---heat---- 2CuO+4NO2+O2
