(i) Reactants: Zn, HNO3; Products: Zn(NO3)2, H2
Balacned equation: Zn(s) + 2HNO3(aq) ----> Zn(NO3)2(aq) + H2(g)
Total ionic equation: Zn(s) + 2H+(aq) + 2NO3-(aq) ----> Zn2+(aq) + 2NO3-(aq) + H2(g)
Net ionic equation: Zn(s) + 2H+(aq) ----> Zn2+(aq) + H2(g)
The element that is oxidized = Zn, the element that is reduced = H
(ii) Reactants: Cu, HNO3; Products: Cu(NO3)2, NO2, H2O
Balacned equation: Cu(s) + 4HNO3(aq) ----> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
Total ionic equation: Cu(s) + 4H+(aq) + 4NO3-(aq) ----> Cu2+(aq) + 2NO3-(aq) + 2NO2(g) + 2H2O(l)
Net ionic equation: Cu(s) + 4H+(aq) + 2NO3-(aq) ----> Cu2+(aq) + 2NO2(g) + 2H2O(l)
The element that is oxidized = Cu, the element that is reduced = N
(iii) Reactants: Pb, HNO3; Products: Pb(NO3)2, H2
Balacned equation: Pb(s) + 2HNO3(aq) ----> Pb(NO3)2(aq) + H2(g)
Total ionic equation: Pb(s) + 2H+(aq) + 2NO3-(aq) ----> Pb2+(aq) + 2NO3-(aq) + H2(g)
Net ionic equation: Pb(s) + 2H+(aq) ----> Pb2+(aq) + H2(g)
The element that is oxidized = Pb, the element that is reduced = H
