For the following double replacement reaction:
ZnBr2 + Na3PO4 ⟶ NaBr + Zn3(PO4)2
Suppose 20.20 g ZnBr2 react with 20.20 g Na3PO4. Which reactant is the limiting reactant? How many grams of Zn3(PO4)2 will be produced?

Answer 1

Trisodium Phosphate + Zinc Bromide = Sodium Bromide + Zinc Phosphate
Two moles of aqueous Trisodium Phosphate [Na3PO4] and three moles of aqueous Zinc Bromide [ZnBr2] react to form six moles of aqueous Sodium Bromide [NaBr] and one mole of solid Zinc Phosphate [Zn3(PO4)2]
