Question

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

determine the moles of CO required to make 10g of iron.

Answer 1

Could you redo that using the equation button?

Answer 2

I wanna know which ones are subscripts.

Answer 3

Hey, you still alive?

Answer 4

Also, you know the steps to reach the solution right?

Answer 5

First, convert the mass of the iron to moles. then, find the ratio between the 2. Once you're done that, find the moles of CO.

Answer 6

oh right yeah im still alive just exploded myself :(

Answer 7

lol kay soo umm anyone know how to do this question

Answer 8

the ans is (10/56)*(3/2)

Answer 9

Answer 20

alri thanks

Answer 21

\[10.0 g Fe (\frac{1 mole Fe}{55.85 g Fe})(\frac{3 mole CO}{2 mole Fe})(\frac{28.01 g CO}{1 mole CO})=7.52 g CO\]

Answer 22

\[10.0 g Fe (\frac{1 mole Fe}{55.85 g Fe})(\frac{3 mole CO}{2 mole Fe})=0.269 mole CO\]
I went to grams with the first one then read you needed moles. So i redid it and you need .269 moles of CO to make 10 g Fe.

Answer 23

thanks :)
