Chemical Reactions
  1. 2. Activation energy
    1. Definition: The amount of energy needed to get a reaction started is called the activation energy.
      1. Example: A match wouldn't light up without striking it and by striking it you are causing a activation reaction. A candle wouldn't burn unless you strike a match to it.
    2. 3. Changing Bonds
      1. 4. Exothermic Reactions and Endothermic Reactions
        1. 1. Intro- definition and example
          1. A teacher heats a small piece of sodium. When the sodium cathches fire, she places it in a flask of chlorine. The sodium continues to burn and eventually withe fumes are produced.
            1. It is when substances are broken apart and making new ones from the pieces.
