< 2 of 30 Review | Constants | Periodic Tab Balancing equations with polyatomic ions When balancing chemical equations with polyatomic ions, it may help to balance the ion as a whole. For example, the ion Podca 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 Part B Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction:...

I Review I Constants I Periodic Table When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of Part A 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...
