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.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is minerals.
