2. Consider the reaction below: sodium phosphate can be used in a reaction to precipitate calcium ions out of hard water. This reaction is often used in commercial water softeners. CaCl2(aq) + Na3PO4(aq) ⟶ Ca3(PO4)2(s) + NaCl(aq)
• Balance the equation above.

• Calculate the theoretical yield of calcium phosphate given the following information: 1.33 kilograms of calcium chloride is reacted with excess sodium phosphate, and 405 grams of calcium phosphate are produced. Work must be shown to earn credit.

• Use the information above to calculate the percent yield. Work must be shown to earn credit.
