CHEMICAL EQUATIONS ** A chemical equation describes what happens in a chemical **[|reaction]**. The equation identifies the **[|reactants]** (starting materials) and **[|products]** (resulting substance), the **formulas ** of the participants, the **phases ** of the participants (solid, liquid, gas), and the **amount **of each substance, given by the **coefficient **, which is the number in front of the formulas or symbols and it means the amount of moles of substance (number one is understood). Example: Reaction: 4Na(s) + O2(g) → 2Na2O(s) Reactants: 4Na(s) + O2(g) Products: 2Na2O(s) Formulas and symbols: Na, O2, Na2O Phases: (g), (s), (l), (aq) Coefficients: 4 + 1 2
