Can someone help me balance this equation? ?

Question

Fe2O3 + CO -> Fe + CO2

and if anyone is willing to chat with me and help me with my homework overall. its hard to have to do all this just for one little question. I wish I had someone who was just there to answer my little questions. :(

Answer 1

Fe2O3 + 3CO --> 2Fe + 3CO2

Email if you need more help.

Answer 2

Fe2O3 + 3 CO -> 2Fe + 3 CO2

Answer 3

Fe2O3 + CO --> Fe + CO2

first balance the Fe

Fe2O3 + CO --> 2 Fe + CO2

each CO can add 1 O to become CO2; you need 3CO

Fe2O3 + 3 CO --> 2 Fe + 3CO2

It's now balanced
