Stoichiometry Review Game!
Find the molar mass of:
NaNO3
Find the molar mass of:
Ca3(PO4)2
How many grams is 31 moles of NaCl?
How many moles is 7 grams of CO2?
Balance:
__ Fe + __H2O  __ Fe3O4 + __ H2
Using this chemical equation:
_3_Fe + _4_H2O  _1_Fe3O4 + _4_H2
What is the mole ratio of H2O to Fe3O4?
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?
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?
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?
Using this chemical equation:
_3_Fe + _4_H2O  _1_Fe3O4 + _4_H2
What is the molar mass of Fe3O4?
Using this chemical equation:
_3_Fe + _4_H2O  _1_Fe3O4 + _4_H2
What is the sum of the coefficients?
Balance:
___ CaCO3 + ___ HCl 
___ CaCl2 + ___ CO2 + ___ H2O
Using this chemical equation
CaCO3 + 2 HCl  CaCl2 + CO2 + H2O
What is the sum of the coefficients?
(Hint: It is already balanced!)
Write the formula for all 7 of the
diatomic elements.
