Identify The Atoms That Are Oxidized And Reduced The Change In Oxidation State F

Identify the atoms that are oxidized and reduced, the change in oxidation state for each, and the oxidizing andreducing agents in each of the following equations:

(a) Mg(s) + NiCl2(aq) ⟶ MgCl2(aq) + Ni(s)

(b) PCl3(l) + Cl2(g) ⟶ PCl5(s)

(c) C2 H4(g) + 3O2(g) ⟶ 2CO2(g) + 2H2 O(g)

(d) Zn(s) + H2SO4(aq) ⟶ ZnSO4(aq) + H2(g)

(e) 2K2S2 O3(s) + I2(s) ⟶ K2S4 O6(s) + 2KI(s)

(f) 3Cu(s) + 8HNO3(aq) ⟶ 3Cu(NO3)2(aq) + 2NO(g) + 4H2 O(l)
