how many molecule of carbon dioxide are needed to react with excess iron oxide to produce 11.6 g of iron

0.16 moles of Carbon

Explanation:

The balanced reaction equation:

+ → + ↑

The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)

i.e 3 moles of C produces 4 moles of Fe.

If 1 mole of Fe - 55.8g of Fe

? moles - 11.6g of Fe

= = 0.208 moles

But 3 moles of C - 4 moles of Fe

? moles of C - 0.208 moles of Fe

= = 0.16 moles of carbon.

I hope this explanation was clear and useful.

it is a good conductor
