Question

Which is the properly balanced equation for the process in which iron oxide (Fe2O3) and carbon monoxide (CO) react to produce iron (Fe) and carbon dioxide (CO2) gas?

A.
Fe2O3 + CO → Fe + CO2

B.
Fe2O3 + 3CO → 2Fe + 3CO2

C.
2Fe2O3 + 3CO → 2Fe + 3CO2

D.
3Fe2O3 + CO → 3Fe + 2CO2

Answer 3

what you need to do is count the number of atoms of each element on the left of the equation and see if the number on the right is the same

Answer 4

take A:=
Fe2O3 - there are 2 Fe here
look at right side - there is only 1 Fe

so A does not balance and is not the answer


get the idea?
