Answer:
1 Al(NO3)3 + 1 (NH4)3PO4 → 1 AlPO4 + 3 NH4NO3
Explanation:
To balance Al(NO3)3 + (NH4)3PO4 → AlPO4 + NH4NO3 you'll need to be sure to count all of the atoms on each side of the chemical equation. Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation.
