The first question is "how many moles of carbon monoxide (co) are required to react completely with 1.75 moles of iron (iii) oxide (fe2o3)? "if this is not the question you see, click new questions until it appears) what unit is given in the question? what quantity is asked for?

5.25 moles of carbon monoxide are required.

Explanation:

Moles of of iron (iii) oxide = 1.75 moles

According to reaction , 1 mole of iron (iii) oxide reacts with 3 moles of carbon monoxide.

Then 1.75 mol of iron (iii) oxide will react with :

of iron (iii) oxide

5.25 moles of carbon monoxide are required.
