Problem

Which of the following is an example of a decomposition reaction?

a. HCI(aq) + NaOH(aq) → NaCI(aq) + H 2O(I)

b. 2Pb(NO3)2(s) + heat → 2PbO(S) + 2NO(g) + O 2(g)

c. AgNO3(aq) + Li2SO4(aq) → 2LiNO3(aq) + Ag2O4(S)

d. 2Li(s) + 2H2O(I) → 2LiOH(aq) + H2(g)

e. Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
