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

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

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

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

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

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

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

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
