Elements equations Elements equations Presentation Transcript

  • What are elements and equations?
  • What are elements?
    Elements are the building blocks of matter.
    Matter is everything around you.
  • So what is a chemical equation?
    It is an equation that shows what takes place in the chemical reaction.
    So let’s look at water for an example.
    As we mentioned water is made up of Hydrogen and Oxygen. When those two elements bond a reaction takes place.
    The chemical equation looks like this
    2H2 + O2  2H2O
    So what the equation is telling us is that it takes 2 H molecules and 1 Oxygen molecule to make 2 water molecules
