Question

How many cubic feet of air at a pressure of 760 torr and 0 °c is required per ton of fe2o3 to convert that fe2o3 into iron in a blast furnace?

Answer 1

In a blast furnace, Fe2O3 is converted into iron by reacting with carbon monoxide. The volume of air required per ton of Fe2O3 can be calculated using the volume of carbon monoxide required. However, the question does not provide the amount of Fe2O3, so the exact volume cannot be calculated.

Step-by-step explanation:

In a blast furnace, Fe2O3 is converted into iron. The reaction is:

Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g)

From the balanced equation, we can see that 3 moles of CO are required to convert 1 mole of Fe2O3 into iron.

Given that air is 19% oxygen by volume, we can assume that the volume of air required per ton of Fe2O3 is 19% of the volume of CO required.

To find the volume of air required per ton of Fe2O3, we need to calculate the volume of CO and then multiply it by 0.19.

Since the question does not provide the amount of Fe2O3, we cannot calculate the exact volume of air required.

This is the step-by-step method to calculate the volume of air required per ton of Fe2O3 in a blast furnace.
