Zinc Hydrochloric Acid Zinc Chloride Hydrogen Gas Zn + HCl --> ZnCl2 + H2 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 Hydrogen Oxygen H2O --> H2 + O2 Am I balanced? water as fuel for vehicles? Balance me on the board!
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
