Solution

CA(NO₃)₂, Fe₂S₂, NaSO₄ and Na(CO)₃are the incorrect formulae, while K₂CO₃, Zn(CO₃), Cu₁O₁, HgO, PbCO₃, K₂S₁ and MgSO₄ are correct formulae. Corrected formulae for the incorrect ones are as follows:

FeS is the correct formula for iron sulphide.
Na₂SO₄ is the correct formula for sodium sulphate.
Na₂(CO₃) is the correct formula for sodium carbonate.
Ca(NO₃)₂ is the corrected formula for calcium nitrate.
