Question

The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this reaction in terms of A and B. Express your answer as a chemical equation. Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: ? H3PO4 + ? Mg(OH)2 rightarrow ? Mg3(PO4)2 + ? H2O Balance the equation, then enter the coefficients, in order, in the answer box. Enter four integers separated by commas.

Explanation / Answer

A) 2A + 3B2 -> 2AB3

B) H3PO4 = 2

Mg(OH)2 = 3

Mg(PO4)2 = 1

H2O = 6
