Final answer:
The molecular equation for the reaction between calcium nitrate and sodium phosphate is 3 Ca(NO3)2 (aq) + 2 Na3PO4 (aq) → Ca3(PO4)2 (s) + 6 NaNO3 (aq), indicating the formation of solid calcium phosphate and aqueous sodium nitrate.
Step-by-step explanation:
To write the molecular equation for the reaction of aqueous calcium nitrate with aqueous sodium phosphate, we first need to know the formulas of the reactants and the products they form when they react. Calcium nitrate has the formula Ca(NO3)2 and sodium phosphate is represented as Na3PO4. When these two react, they form calcium phosphate, which is insoluble in water and precipitates out as a solid, with the formula Ca3(PO4)2, and sodium nitrate, NaNO3, which remains in solution.
The balanced molecular equation is:
3 Ca(NO3)2 (aq) + 2 Na3PO4 (aq) → Ca3(PO4)2 (s) + 6 NaNO3 (aq)
This equation indicates that three calcium nitrate formula units react with two sodium phosphate formula units to form one formula unit of calcium phosphate and six formula units of sodium nitrate.
