Question

Na subscript 2SO subscript 4 + CaCl subscript 2 produces CaSO subscript 4 + NaCl

Please help me balance this equation and show your work

Na<sub>2</sub>SO<sub>4</sub> + CaCl<sub>2</sub> --> CaSO<sub>4</sub> + NaCl

We need 2NaCl on the right to balance the Cl from CaCl<sub>2</sub> on the left:

Na<sub>2</sub>SO<sub>4</sub> + CaCl<sub>2</sub> --> CaSO<sub>4</sub> + 2NaCl

Now things balance. This one was easy, since both Ca and SO<sub>4</sub> are -2.
