Verified step by step guidance1
Identify the chemical formulas of the reactants and products: Na3PO4, Ca(NO3)2, NaNO3, and Ca3(PO4)2.
Count the number of atoms for each element on both sides of the equation. For example, count the number of Na, Ca, P, and O atoms in the reactants and products.
Start by balancing the element that appears in the least number of compounds. In this case, balance the calcium (Ca) atoms first.
Next, balance the sodium (Na) atoms by adjusting the coefficients of Na3PO4 and NaNO3.
Finally, balance the phosphate (PO4) groups and nitrate (NO3) groups by adjusting the coefficients of the remaining compounds, ensuring that the number of each atom is equal on both sides of the equation.
