Answer:
a) 2NaOH(aq) + CuSO4(aq) ----> Cu(OH)2(s) + Na2SO4(aq)
b) Ca(OH)2(aq) + CO2(g) --> CaCO3 + H2O (the chemical equation is already balanced as is)
c) Pb(NO3)2 + H2SO4 --> PbSO4 + 2HNO3
d) 2KNO3 --> 2KNO2 + O2
e) H2SO4 + 2(NaOH) --> Na2SO4 + 2(H2O)
f) Ca(NO3)2(aq) + (NH4)2CO3(aq) --> CaCO3(s) + 2NH4NO3(aq)
