- - - - Exothermic reactions give out energy. So there is a temperature rise.
      - the products have lower energy than the reactants.
    - - Endothermic reactions take in energy from their surroundings.
      - the products must have higher energy than the
        reactants.
  - - - When a reversible reaction is in equilibrium and you make a change,
        the system acts to oppose the change, and restore equilibrium.
      - For exothermic, when the temperature increase equilibrium favours the product.
        For endothermic, when the temperature increase equilibrium favours the reactants.
      - if the concentration of reactants is increased, the system will shift toward the products. If more products are added, the system will shift to form more reactants
- - - - The ions form a lattice with two chloride ions for each magnesium ion.
        So the formula of the compound is MgCl2. It has no overall charge.
  - - - Word equation: carbon + oxygen --> carbon dioxide
        Chemical equation: C + O2 -->CO2
    - - The law of conservation of mass states that no atoms are lost or made in a chemical reaction. That's why the number of each type of atom must the same on both sides
      - The sum of the reactants is equal to the sum of the product
- - - - the amount of a reactant used up per unit of time or
        the amount of a product produced per unit of time.
