How do I balance Ca(HCO3)2 + H2SO4 ---> CaSO4 + H2O + CO2

..4H..........
I worked that out myself by showing products. How do I balance this? Or how do I begin?

Ca(HCO3)2 + H2SO4 ---> CaSO4 + H2O + CO2

1Ca.......1Ca
4H.........2H
2C.........1C
10O.......7O
1S.........1S


1)Balance H by putting coefficient of 2 on H2O of product side. This will also add 1 O on product side.
Ca(HCO3)2 + H2SO4 ---> CaSO4 + 2H2O + CO2
1Ca.......1Ca
4H.........4H
2C.........1C
10O.......8O
1S.........1S

2)Balance C by putting coefficient of 2 on CO2 of product side. This will also add 2 more Oxygens on product side and will balance the oxygens.
Ca(HCO3)2 + H2SO4 ---> CaSO4 + 2H2O + 2CO2
1Ca.......1Ca
4H.........4H
2C.........2C
10O.......10O
1S.........1S
