One half of a balanced chemical equation is shown. 3mg(oh)2 + 2h3po4 which lists the numbers of each atom the other half of the equation would contain? 3 mg, 2 p, 14 o, 12 h mg, 2 p, 14 o, 6 h 3 mg, 8 p, 7 o, 6 h 6 mg, 6 p, 2 o, 12 h

Answer is: 3 Mg, 2 P, 14 O, 12 H.

Balanced chemical reaction:  

3Mg(OH)₂ + 2H₃PO₄ → Mg₃(PO₄)₂ + 6H₂O.

There are three magnesium atoms (Mg), two phosphorus atoms (P), fourteen oxygen atoms (O) and twelve hydrogen atoms (H) on both side of balanced chemical reaction.

Mg₃(PO₄)₂ is magnesium phosphate.

3 Mg, 2 P, 14 O, 12 H.
