What substances does dilute sulfuric acid interact with: Ag, FeS, Zn (NO3) 2, Fe, CO2, Al (OH) 3, MgO, BaCl2?

Let’s compose the equations of practically feasible reactions:
H2SO4 + MgO = MgSO4 + H2O;
H2SO4 + BaCl2 = BaSO4 + 2H2O;
Fe + H2SO4 = FeSO4 + H2;
H2SO4 + Zn (NO3) 2 = ZnSO4 + 2HNO3;
H2SO4 + FeS = FeSO4 + H2S;
H2SO4 + Ag – the reaction does not proceed, since the sulfuric acid solution does not react with the metals that stand after hydrogen in the series of voltages.
H2SO4 + Al (OH) 3 – the reaction is not proceeding;
H2SO4 + CO2 – the reaction is not progressing.
The acid solution is used in metal processing plants to remove metal oxides from the surface, as well as in the processing of ores.
