Which of the following reactions are redox reactions?
A) 4Li(s)+O2(g)→2Li2O(s)
B)Mg(s)+Fe2+(aq)→Mg2+(aq)+Fe(s)
C)Pb(NO3)2(aq)+Na2SO4(aq)→PbSO4(s)+2NaNO3(aq)
D)HBr(aq)+KOH(aq)→H2O(l)+KBr(aq)
The first two reactions are oxidation- reduction reactions while the third reaction is double displacement and the fourth one is neutralization reaction invovling an acid and base. Hence the first two are redox reactions.
