Calcium CARBONATE plus sulfuric acid.
Calcium is Ca2+; carbonate is CO3(2-)
So calcium carbonate is CaCO3. Their charges imply that they combine in a 1:1 mole ratio...
Sulfuric acid - memorize it... H2SO4
Now, think "double replacement reaction"...
AB + CD ----> AD + CB
CaCO3 + H2SO4 ------> ?
CaCO3 + H2SO4 -------> CaSO4 + H2CO3
Now remember that
H2CO3 actually dissocates into H2O and CO2
so...
CaCO3 + H2SO4 -------> CaSO4 + H2O + CO2
Ta da...

CaC03+H2SO4 -> CO2 + H2O + CaSO4
Calcium Carbonate + Sulphuric Acid -> Carbon Dioxide + Water + Calcium Sulphate

Gives calcium sulphate + carbon dioxide (+water)
but don't work long 'cos the calcium carbonate is covered with the calcium sulphate produced which is insoluble and stops the acid getting to more calcium carbonate
