Balance the following chemical equation:  (Remember to enter a "1" where you have blanks after balancing.)  Na2(SO4) +  CaCl2 -->  Ca(SO4) +  NaCl

To balance the chemical equation Na2(SO4) + CaCl2 --> Ca(SO4) + NaCl, follow these steps:

1. Identify the atoms or ions that are unbalanced on the reactant and product side of the equation. In this case, the Sodium (Na), Sulfate (SO4), Calcium (Ca), and Chlorine (Cl) atoms are unbalanced.

2. Balance the atoms that appear in complex ions first. In this case, the sulfate (SO4) ions are already balanced.

3. Balance the Sodium (Na) atoms. There are 2 Na atoms on the reactant side and only 1 on the product side. To balance this, place a 2 in front of NaCl on the product side. The equation now reads: Na2(SO4) + CaCl2 --> Ca(SO4) + 2NaCl.

4. Balance the Calcium (Ca) atoms. There is 1 Ca atom on both sides of the equation, so it is already balanced.

5. Finally, balance the Chlorine (Cl) atoms. There are 2 Cl atoms on the reactant side and 2 on the product side (in 2NaCl), so they are already balanced.

6. Check the equation to make sure all atoms are balanced. If each type of atom has the same number on both sides of the equation, it is balanced.

So, the balanced equation is: Na2(SO4) + CaCl2 --> Ca(SO4) + 2NaCl.
