The chemical equation you have provided is unbalanced. To balance it, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
The balanced equation for the reaction between magnesium (Mg) and phosphoric acid (H₃PO₄) is:
3Mg + 2H₃PO₄ → 3MgPO₄ + 3H₂O
In this balanced equation, 3 moles of magnesium react with 2 moles of phosphoric acid to produce 3 moles of magnesium phosphate and 3 moles of water.
