Final answer:
Ca²+ (aq) + 2Cl¯(aq) +3Na+ (aq) +PO⁴³(aq) →Ca3(PO4)2 (s) +3Na+ (aq) + 3Cl¯(aq)
The student is asking to balance a chemical equation for a double replacement reaction combining sodium phosphate and calcium chloride to produce sodium chloride and calcium phosphate.
Step-by-step explanation:
The student's question involves balancing a chemical equation for a double replacement reaction. Given the reactants sodium phosphate (Na3PO4) and calcium chloride (CaCl2), we must balance the equation to find the correct stoichiometric coefficients.
The products of the reaction are sodium chloride (NaCl) and calcium phosphate (Ca3(PO4)2). According to solubility rules, NaCl is soluble and Ca3(PO4)2 is insoluble.
Using the provided information on ionic dissociation, including the fact that NaCl separates into Na+ and Cl¯ ions, we can determine the balanced equation.
The balanced ionic equation for the products then looks like this:
Ca²+ (aq) + 2Cl¯(aq) +3Na+ (aq) +PO⁴³(aq) →Ca3(PO4)2 (s) +3Na+ (aq) + 3Cl¯(aq)
