  1. Stoichiometry Review Game!

  2. Rules Students are in pairs of two and are given a short amount of time to write down their answer on a dry erase board. When time is up, each pair of students holds up their answer. Afterwards, I explain how to find the right answer for the benefit of the entire class, especially those students who need a little refresher.

  3. Find the molar mass of: NaNO3

  4. Find the molar mass of: Ca3(PO4)2

  5. How many grams is 31 moles of NaCl?

  6. How many moles is 7 grams of CO2?

  7. Balance: __ Fe + __H2O  __ Fe3O4 + __ H2

  8. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 What is the mole ratio of H2O to Fe3O4?

  9. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 How many moles of Fe3O4 will you get if you start with 2.7 grams of Fe?

  10. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 How many grams of H2 will you get if you start with 4 moles of H2O?

  11. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 How many moles of Fe3O4 would be produced if you used 7 moles of Fe?

  12. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 What is the molar mass of Fe3O4?

  13. Using this chemical equation: _3_Fe + _4_H2O  _1_Fe3O4 + _4_H2 What is the sum of the coefficients?

  14. Balance: ___ CaCO3 + ___ HCl  ___ CaCl2 + ___ CO2 + ___ H2O

  15. Using this chemical equation CaCO3 + 2 HCl  CaCl2 + CO2 + H2O What is the sum of the coefficients? (Hint: It is already balanced!)

  16. Write the formula for all 7 of the diatomic elements.

  17. Extra Credit Opportunity! E-mail Ms. Barrow with a link to a website about stoichiometry and two sentences explaining how it helped you study. Must be sent to me before your test next week. Worth 5 extra points on your homework packet! :)
