When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. 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. When balancing chemical equations with polyatomic ions, it may help to balance the ion as a whole. For example, the ion PO_4^3 can be treated as a unit and balanced in both the reactants and the product, or you can break it down and balance each atom separately. Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: Balance the equation, then enter the coefficients, in order, in the answer…
