Calcium phosphate is used as an antacid, supplement, and/or a source of calcium and phosphate in toothpaste.In a laboratory setup calcium hydroxide can be reacted with phosphoric acid to produce calcium phosphate with water as by-product.In an experimental process, there are three procedures to deal with in the production of calcium phosphate.Procedure 1: 846.0 grams of calcium oxide and 264.0 grams of water are combined in order to produce a single product, calciumhydroxide.Procedure 2: 979.0 grams of diphosphorus pentoxide and 323.0 grams of water are combined in order to produce a single product,phosphoric acid.Procedure 3: Actual mass of isolated calcium hydroxide from Procedure 1 and actual mass of isolated phosphoric acid fromProcedure 2 are combined in order to produce calcium phosphate with water as by-product.It is also noted that each procedure had the following percent yields:Procedure 1: 53.58% yield on calcium hydroxide.Procedure 2: 59.26% yield on phosphoric acid.Procedure 3: 31.41% yield on calcium phosphate. Which of the following balanced chemical equations pertains to the chemical reaction involved in Procedure 3?
