a. 3MnO2 + 4Al - > 3Mn + 2Al2O3

3 moles of MnO2 required 4 moles of Al to produce 3 moles of Mn and 2moles of 2Al2O3

b. B203 + 3CaF2 - > 2BF3 + 3CaO

1mole of B203 requires 3 moles of CaF2 to produce 2moles of BF3 and 3 moles of CaO

c. 3NO2 + H2O - > 2HNO3 + NO

3 moles of NO2 requires 1mole of H2O to produce 2moles of HNO3 and 1mole of NO

d. C6H6 + 3H2 - > C6H12

1mole of C6H6 requires 3 moles of H2 to produce 1mole of C6H12
