  1. 1. The mass of a product that a chemical reaction makes in real life. It is usually less than the theoretical yield, for a number of reasons
  2. 3. Dissolved in water to form a solution. Shown as (aq) in chemical equations.
  3. 4. The reacting substance that is completely used up in a chemical reaction and which determines how much product is made.
  4. 6. The maximum possible mass of a product that a chemical reaction can make. It is calculated using molar ratios.
  5. 7. The amount of substance that contains the same number of particles as there are atoms in 12 g of carbon-12 (contains the Avogadro's constant 6.0 ×10²³ number of particles).
  6. 9. A way of writing out what happens in a chemical reaction.
