  1. Balancing Chemical Equations • Matter is neither created or destroyed in a chemical change

  2. Laws • In most of life, laws get broken • “Speed Limit is 25mph” • People do go 26 though!

  3. Natural Laws • Scientific Laws do not have exceptions • Law: Conservation of mass / matter • Matter is neither created or destroyed in a chemical change

  4. Zinc Hydrochloric Acid Zinc Chloride Hydrogen Gas Zn + HCl --> ZnCl2 + H2 Am I balanced? Balance me on the board!

  5. Hydrogen Gas Oxygen Gas Steam H2 + O2--> H2O Am I balanced? Balance me on the board!

  6. Water Hydrogen Oxygen H2O --> H2 + O2 Am I balanced? water as fuel for vehicles? Balance me on the board!

  7. Baking Soda Vinegar Carbon Diox, water, white solid NaHCO3 + HC2H3O2 --> CO2 + H2O + NaC2H3O2 Am I balanced? Yes!!!

  8. Work in your groups • I think this is hard. Balance: • Fe + S --> FeS • H2 + Cl2 --> HCl • I think I get this. Balance: • Ca + H20 --> Ca(OH)2 + H2 • C2H6 + O2 --> CO2 + H2O
