Answer: 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
Explanation:
The balanced chemical equation is:
According to stoichiometry :
2 moles of require 3 moles of
Thus both are limiting reagent as both will limit the formation of product.
As 2 moles of reacts with 3 moles of
give = 6 moles of
Thus 6 moles of NaCl are produced when 2 moles of sodium phosphate reacts with 3 moles of calcium chloride
