Chemical Equations 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. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are same on both sides of the arrow. Part A The Figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (spheres). reaction in terms A and B Express your answer as a chemical equation. Balancing equations with polyatomic icons When balancing chemical equations with polyatomic icons. It may be balance the icon as a whole. For example the icon PO_4^2 can be as a and balanced both the reactants and the product, or you can 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 ?H_3PO_5 + ?Mg(OH)_2 rightarrow ?Mg_3(PO_4)_2 + ?H_2O Balance the equation, then enter the coefficients, in order in the answer box. Enter your integers separated commas.
