Just this problem please
_Ca3(PO4)2 + _H2SO4 ---> _CaSO4 + _Ca(H2PO4)2
Thanks in advance!
_Ca3(PO4)2 + _H2SO4 ---> _CaSO4 + _Ca(H2PO4)2
Thanks in advance!

1 2 2 1 is balanced I believe

Ca3(PO4)2(s) + 2H2SO4(aq) ---> 2CaSO4(s) + Ca(H2PO4)2(aq)
The equation as presented is a bit dodgy because there will be many more species than these actually in solution. Calcium phosphate is insoluble in water, but will react with sulfuric acid. Calcium sulfate is fairly insoluble. In addition to the "monocalcium phosphate", which is somewhat soluble in water, there will be the following ions in solution: Ca2+, H+, H2PO4^-, HPO4^2-, PO4^3-, and H3PO4. The concentrations of these will depend on the pH, which will depend on the amount of any excess sulfuric acid in the reaction mixture.
