Answer 1

a) 1.Na
2.2Na+Zn(OH)2=2NaOH+Zn
3.2NaOH+CaCo3=Na2Co3+Ca(OH)2
4.Na2Co3+2HCL=2NaCL+Co2+H2O
5.2NaCL+ZnSO4=Na2SO4+ZnCL2.
б) 1.Ca
2.2Ca+O2=2CaO
3.CaO+2KOH=Ca(OH)2+K2O
4.Ca(OH)2+Na2Co3=CaCo3+2NaOH
5.CaCo3+2KNO3=Ca(No3)2+K2Co3
в)1.Cu
2.2Cu+O2=2CuO
3.CuO+2NaCL=CuCL2+Na2O
4.CuCL2+2KOH=Cu(OH)2+2KCL
5.Cu(OH)2+Li2O=CuO+2LiOH
6.2CuO=2Cu+O2
