An acid (x) reacts with a base (y) to produce mg3(po4)2. what are x and y? x = h3po3; y = mg(oh)2 x = h3po4; y = mg(oh)2 x = h3po4; y = ca(oh)2 x = h3po3; y = ca(oh)2

The correct answer is  

Explanation:

Reaction between a base and an acid is defined as a type of neutralization reactions.

These are the type of reaction in which an acid reacts with a base to produce a salt and water molecule. The general equation for this reaction follows:

It is given that the salt produced is . So, the acid must be phosphoric acid and the base must be magnesium hydroxide.

The reaction between the two follows the chemical equation:

Hence, the correct answer is
