उत्तर
Zinc Sulphate – Displacement
\[\ce{Zn + H2SO4 -> ZnSO4 + H2\uparrow}\]
Ferrous sulphide – Synthesis
\[\ce{Fe + S ->[\Delta] FeS}\]
Barium sulphate – Precipitation
\[\ce{BaCl2 + H2SO4 -> BaSO4\downarrow + 2HCl}\]
Ferric sulphate – Oxidation
\[\ce{4FeO + O2 -> 2Fe2O3}\]
Sodium sulphate – Neutralisation
\[\ce{Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2\uparrow}\]
