# Problem: Directions: You must solve each of the following problems using dimensional analysis. EVERY number in you work should be followed by a unit and a formula. 3.  For this reaction: ___ Fe3O4 + ____CO → _____ Fe + ______CO2a. How many moles of carbon dioxide are produced from 2.87 moles of Fe3O4? b. How many moles of carbon monoxide are needed to react with 8.25 moles of Fe3O4?

We're given the following reaction:

___ Fe3O4 + ____CO → _____ Fe + ______CO2

Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.

Reaction 1:

 ___ Fe3O4 + ___CO → ___ Fe + ___CO2 Fe      3O      4+1 = 5 C      1 Fe     1O      2C      1
