Question

Which of the following is a valid mole ratio from the balanced equation 2Fe2O3 + 3C —> 4Fe + 3CO2? (4 points)

a. 4 mol C
b. 3 mol Fe
c. 2 mol Fe2O3
d. 4 mol CO2

Answer 1

The valid mole ratio from the balanced equation 2Fe2O3 + 3C —> 4Fe + 3CO2 is 2 mol Fe2O3.

Step-by-step explanation:

The valid mole ratio from the balanced equation 2Fe2O3 + 3C —> 4Fe + 3CO2 is c. 2 mol Fe2O3.

In the equation, the coefficient of Fe2O3 is 2, indicating that for every 2 moles of Fe2O3, 4 moles of Fe are produced. Therefore, the mole ratio is 2:4, which can be simplified to 1:2.

So, the correct answer is c. 2 mol Fe2O3.
