Question

5 Consider the following chemical reaction. 3 Zn(C?H?O?)?(aq) + 2 Na?PO?(aq) ? 6 NaC?H?O?(aq) + Zn?(PO?)?(s) a If sodium phosphate is in excess in the following balanced chemical equation, what compound is the limiting reactant? b A chemist makes a solution of zinc acetate by dissolving 20.5 g Zn(C?H?O?)? in 105 mL H?O. What is the concentration of this zinc acetate solution? c How many moles of aqueous zinc acetate will react with excess aqueous sodium phosphate to precipitate one mole of solid zinc phosphate? d The chemical formula of zinc phosphate is Zn?(PO?)?. What is the formula weight of zinc phosphate? Provide an answer to two decimal places. e Calculate the mass in grams Zn?(PO?)? that can be precipitated from 0.105 L of a 1.06 M Zn(C?H?O?)? solution by the reaction with excess aqueous sodium phosphate (Na?PO?) according to the following balanced chemical equation: 3 Zn(C?H?O?)?(aq) + 2 Na?PO?(aq) ? 6 NaC?H?O?(aq) + Zn?(PO?)?(s) f In the reaction of 20.5 grams of Zn(C?H?O?)? with excess Na?PO?, would you expect the total mass of Zn?(PO?)? precipitated to be greater than, less than, or equal to the mass of the zinc acetate?
