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

Answer:

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

Explanation:

Step1: Count Mg atoms

In $3Mg(OH)_2$, there are $3\times1 = 3$ Mg atoms.

Step2: Count P atoms

In $2H_3PO_4$, there are $2\times1=2$ P atoms.

Step3: Count O atoms

In $3Mg(OH)_2$, there are $3\times2 = 6$ O atoms from the hydroxide part. In $2H_3PO_4$, there are $2\times4 = 8$ O atoms from the phosphate part. So in total, $6 + 8=14$ O atoms.

Step4: Count H atoms

In $3Mg(OH)_2$, there are $3\times2 = 6$ H atoms from the hydroxide part. In $2H_3PO_4$, there are $2\times3 = 6$ H atoms from the phosphate part. So in total, $6+6 = 12$ H atoms.
