  1. Intro to Stoichometry

  2. Mole Ratio

  3. Predict the products and balance the following equation: Li + O2

  4. Predict the products and balance the following equation: 4 Li + O2 2 Li2O 4 moles of Li react with 1 mol of O2 to produce 2 moles of Li2O

  5. 4 Li + O2 2 Li2O If 1.83 mol of Li reacted, how many moles of O2 reacted? • What is the mole ratio of Li to O2? From the balanced reaction:

  6. 4 Li + 1 O2 2 Li2O If 1.83 mol of Li react, how many moles of O2 react? This is called the “Mole Ratio”

  7. 4 Li + O2 2 Li2O If 1.83 mol of Li reacted, how many moles of Li2O will be produced? “Mole Ratio” between Li2O and Li

  8. Predict the products and balance the following equation: FeS

  9. Predict the products and balance the following equation: 8 FeS 8 Fe + S8 • If 4.18 mol FeS decomposes, how many moles of Fe are produced? 4.18 molFe • How many moles of sulphur are produced? 0.523 mol S

  10. Predict the products and balance the following equation: Lead reacts with copper(I) sulphate. Pb + Cu2SO4 

  11. Predict the products and balance the following equation: Pb + Cu2SO4  PbSO4 + 2Cu • If 9.78 mol of Cu is produced, how many moles of Pb reacted? 4.89 molPb • If 3.45 mol Cu2SO4 reacts, how many moles of PbSO4 are produced? 3.45 mol PbSO4
