For each reaction, calculate the moles of product (in parentheses) when 2.00 moles of each reactant is used
A: 2SO2 + O2 = 2SO3 (SO3)
B: 3Fe + 4H2O = Fe3O4 + 4H2 (Fe3O4)
C: C7H16 + 11O2 = 7CO2 + 8H2O (CO2)
Didn't Bob Pursley do one like this for you. You should have learned how to do it from that. Explain what your trouble is.
This is a limiting reagent problem. Here is a site that explain exactly how do do those.
