question 17

Multiple Choice

When mixed, solutions of silver nitrate, AgNO₃, and sodium phosphate, Na₃PO₄, will form a precipitate of silver phosphate, Ag₃PO₄.The balanced equation is 3AgNO₃(aq) + Na₃PO₄(aq) $\rightarrow$ Ag₃PO₄(s) + 3NaNO₃(aq) Which of the following statements regarding this reaction is incorrect?

• A)6 moles of AgNO₃ will react with 2 moles of Na₃PO₄.
• B)9 moles of AgNO₃ should react to form 2 moles of Ag₃PO₄, given sufficient Na₃PO₄.
• C)1.5 moles of NaNO₃ should form when 0.5 mole of Na₃PO₄ reacts with sufficient AgNO₃.
• D)3 moles of Ag₃PO₄ should form when 3 moles of Na₃PO₄ react with sufficient AgNO₃.
• E)2 moles of Na₃PO₄ will react with 6 moles of AgNO₃.
