Na subscript 2SO subscript 4 + CaCl subscript 2 produces CaSO subscript 4 + NaCl
Please help me balance this equation and show your work

Na_{2}SO_{4} + CaCl_{2} > CaSO_{4} + NaCl
We need 2NaCl on the right to balance the Cl from CaCl_{2} on the left:
Na_{2}SO_{4} + CaCl_{2} > CaSO_{4} + 2NaCl
Now things balance. This one was easy, since both Ca and SO_{4} are 2.
