A chemical equation, like 2 H₂ + O₂ → 2 H₂O , is a symbolic representation of a chemical reaction. Balancing this equation ensures that it obeys the Law of Conservation of Mass, meaning there are equal numbers of each type of atom on both sides of the arrow. is the field of chemistry that uses these balanced equations to calculate the quantities of reactants and products in a chemical reaction. It relies on the mole , a unit representing 6.022 × 10²³ particles, allowing chemists to "count" atoms and molecules by weighing them. Stoichiometry helps answer questions like, "How much product will this reaction make?" or "How much reactant do I need to start with?".
