When mixed, solutions of copper(II) nitrate, Cu(NO3) 2, and sodium phosphate, Na3PO4, will form a precipitate of copper phosphate, Cu3(PO4) 2.The balanced equation is 3Cu(NO3) 2(aq) + 2Na3PO4(aq) Cu3(PO4) 2(s) + 6NaNO3(aq) Which of the following statements regarding this reaction is incorrect?
A) 8 moles of Na3PO4 will react with 12 moles of Cu(NO3) 2.
B) 1 mole of NaNO3 should form when 0.5 mole of Cu(NO3) 2 reacts with sufficient Na3PO4.
C) 12 moles of Cu3(PO4) 2 should form when 36 moles of Cu(NO3) 2 reacts with sufficient Na3PO4.
D) If 10 moles of Na3PO4 react with sufficient Cu(NO3) 2, 4 moles of Cu3(PO4) 2 should form.
E) If 5 moles of Cu3(PO4) 2 are needed, it would require the combination of 15 moles of Cu(NO3) 2 and 10 moles of Na3PO4.
