H2SO4 + CaCO3 ---> CaSO4 + H2O + CO2 Sulphuric acid reacts with calcium carbonate, forming calcium sulphate.
Sulphuric acid reacts with sodium hydrogen carbonate to produce sodium sulfate, carbon dioxide, and water.
NO!
When an acid reacts with a carbonate, a salt, CO2, and water is formed. For example: HCl + NaCO3 ---> NaCl + CO2 + H2O
Copper sulphate CuSO4
no hidro means water

Sodium sulphate + water formed
calcium sulfate and water
Sulphurous acid is formed when sulphur dioxide dissolves in water. Sulphuric acid is formed when sulphur trioxide dissolves in water. Over time, sulphurous acid will oxidize to sulphuric. SO2 + H20 -> H2SO3 (sulphurous acid) SO3 + H20 -> H2SO4 (sulphuric acid)
calcium propionate is formed
