How much water vapor was formed?3.

3. 8.45 g of Aqueous potassium phosphate is reacted with 6.23 g of calcium nitrate. a. Write the balanced chemical equation. b. What is the limiting reactant?c. What is the theoretical yield of Ca3(PO4)2?d. If 2.42 g of Calcium phosphate is filtered out of the resulting solution, what is the actual yield?e. What is the percent yield of this reaction?f. How much of the excess was left over?4.

4. 5.67 grams of nickel (III) acetate is added to 85.6 mL of a 0.786 M lithium carbonate and allowed to react. a. Write the balanced chemical equation. b. What is the limiting reactant?c. What is the theoretical yield of the Ni2(CO3)3? d. If 3.58 g of nickel (III) carbonate is filtered out of the resulting solution, what is the actual yield?e.
