Presentation Transcript

  1. BALANCING CHEMICAL EQUATIONS

  2. SnO2 + H2 -> Sn + H2O • Mathematical relationship between the reactants and the products:

  3. SnO2 + H2 -> Sn + H2O • Mathematical relationship between the reactants and the products: • 1) Identify which atoms are not balanced

  4. SnO2 + H2 -> Sn + 2H2O • Mathematical relationship between the reactants and the products: • 1) Identify which atoms are not balanced • 2) Place coefficients to correct and balance

  5. SnO2 + H2 -> Sn + 2H2O • Mathematical relationship between the reactants and the products: • 1) Identify which atoms are not balanced • 2) Place coefficients to correct and balance • 3) Determine and correct, any newly unbalanced reactants &/or products

  6. SnO2 + 2H2 -> Sn + 2H2O • Mathematical relationship between the reactants and the products: • 1) Identify which atoms are not balanced • 2) Place coefficients to correct and balance • 3) Determine and correct, any newly unbalanced reactants &/or products • 4) Correct with coefficient
