Mercurous nitrate is Mercury (I) nitrate and has the formula Hg2(NO3)2. This is not a typo, Apparently the compound is stable with two Hg atoms, but not with one. Mercurous sulfate is mercury (I) sulfate, and has the formula Hg2SO4. Lead (II) nitrate has the formula Pb(NO3)2, and lead (II) sulfate has the formula PbSO4. The following is the balanced chemical equation.
PbSO4 + Hg2(NO3)2 ---> Pb(NO3)2 + Hg2SO4
However, this reaction would not occur. In order for this type of reaction (a double replacement) to occur, the reactants must be dissolved in an aqueous solution. Lead sulfate is an insoluble solid in water. So the equation should really look like this:
PbSO4 + Hg2(NO3)2 ---> no reaction
The double replacement reaction involving these compounds would be:
Pb(NO3)2(aq) + Hg2SO4(aq) ---> PbSO4(s) + Hg2(NO3)2(aq)
(NH4)2SO4 + Ba(NO3)2 -> BaSO4 + 2NH4NO3
This is a single replacement reaction. Zinc is more reactive than copper, so it replaces it and bonds with sulfate. The balanced equation is Zn + CuSO4 => Cu + ZnSO4 (zinc always has a charge of +2)
I will assume you mean lead with a 2 oxidation state. MgSO4 + Pb(NO3)2 >> Mg(NO3)2 + PbSO4
Pb2+ + SO42- --> PbSO4
No Any reaction occurs...
2AgNO3 + CaSO4 ------> Ag2SO4 + Ca(NO3)2
(NH4)2SO4 + Ba(NO3)2 -> BaSO4 + 2NH4NO3
2Fe(NO3)3 + 3Na2SO4 -> Fe2(SO4)3 + 6NaNO3
This is a single replacement reaction. Zinc is more reactive than copper, so it replaces it and bonds with sulfate. The balanced equation is Zn + CuSO4 => Cu + ZnSO4 (zinc always has a charge of +2)
Ba(NO3)2aq) + Li2SO4(aq) → BaSO4(s) + 2LiNO3(aq) Apologies as I can't subscript using my mobile.
Pb2+ + SO42- --> PbSO4
I will assume you mean lead with a 2 oxidation state. MgSO4 + Pb(NO3)2 >> Mg(NO3)2 + PbSO4
Sodium Nitrate is NaNO3 Iron sulfate (I am assuming that you are referring to iron (ii)) is FeSO4 2 NaNO3 + 1 FeSO4 --> 1 Na2SO4 + 1 Fe(NO3)2 This is a double replacement reaction, and it occurs because Fe(NO3)2 is a precipitate.

SO42- + Ba2+ --> BaSO4
This is not 'the balanced equation' of MgSO, what is meant is the chemical FORMULA of magnesium sulfate or magnesium sulfite.These are: MgSO4 and MgSO3respectively.
