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      3

O      4+1 = 5 

C      1

Fe     1

O      2

C      1
