15? Idk I'm guessing I'm sorry
Answer:
3 Mg, 2 P, 14 O, 12 H
Explanation:
Without mincing words, let us dive straight into the solution for the problem above. This question is all about how how equations showing chemical reactions are being balanced.
From the question, we are giving the reactants: which are Mg(OH)2 and H3PO4 and in order to balance the reaction, the number of atoms in the reactants must be equal to the number of atoms in the products side of the reaction. Since, we have 3 Magnesium atoms, 2 Phosphorus atoms, 14 Oxygen atoms, and 12 Hydrogen atoms in the reactants side of the equation, the same number of atoms is expected in the products side.
