How do i Balance THIS...?

SO2 (g) + CaCO3(s) → CaSO4 (s) + CO2 (g)

Update:

ya your right thanks, but if i do this is it correct ?

2SO2 (g) + 2CaCO3(s) + O2(g)→ 2CaSO4 (s) + 2CO2 (g)

Update 2:

ya your right thanks, but if i do this is it correct ?

2SO2 (g) + 2CaCO3(s) + O2(g)→ 2CaSO4 (s) + 2CO2 (g)

    Something is wrong. This is an impossible equation to balance.

    S appears on both sides of the equation a single time. Therefore, the molar ratio between SO2 and CaSO4 is 1:1.

    Ca appears on both sides once, too. Therefore, the molar ratio between CaCO3 and CaSO4 also has to be 1:1.

    Lastly, Carbon appears on both sides a single time. This means that the molar ratio between CaCO3 and CO2 has to be 1:1.

    It is physically impossible to satisfy this equation.

    EDIT: Yeah, if you can add oxygen there then that would make everything work.
