Expert Solution
Step 1
By using stoichiometric coefficient,we can balance the chemical Reactions -
(a) When aqueous sodium phosphate reacts with calcium chloride then due to double substitution (double displacement)reaction sodium chloride and calcium phosphate are formed as -
2Na3PO4(aq) + 3CaCl2(aq) ----> 6NaCl(aq) + Ca3(PO4)2(s)
(Na=6, P=2,O=8,Ca=3,Cl=6 ---> Na=6, Cl=6,Ca=3,P=2,O=8)
