Question

1) Zn-ZnO-ZnSo4-Zn(OH)2-ZnCl2-Zn(OH)2-ZnO-Zn

2)Cu -> CuO -> CuCl2 -> Cu(OH)2 -> CuO -> Cu(NO3)2-> CuO -> Cu

Answer 1

2 Zn+ O2 = 2 ZnO

ZnO+ C = Zn+ CO 

ZnO + H2SO4= ZnSO4 + H2O 

 

2Cu+O2=2CuO

CuO+2HCl = CuCl2 + H2O

 CuCl2+2NaOH = Cu(OH)2 + 2NaCl

Cu(OH)2 + 2HNO3 = Cu (NO3)2 +2 H2O

3CuO+2NH3= 3Cu + N2 + 3H2O
