Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: ?H3PO4 + ?Mg(OH)2->?Mg3(PO4)2 + ?H2O

Balance the equation, then enter the coefficients, in order, in the answer box.
Enter four integers separated by commas.

2, 3, 1, 6.

Explanation:

2H3PO4 + 3Mg(OH)2 --> Mg3(PO4)2 + 6H2O

This is a neutralisation reaction because it is the reaction between acid and base to give a salt and water.

The RHS is the first to be balanced, Mg atom is first balanced, followed by the P atom.

This is because the excess O and H atoms can be balanced on the LHS.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
