Question

how many moles of carbon monoxide are needed to react completely with 1.75 moles of iron oxide

Answer 1

Can you write a balanced chemical reaction equation of iron oxide and carbon monoxide?

Answer 2

is that Iron (III) oxide?

Answer 3

Most likely. It's the most common form

Answer 4

Iron (III) oxide\[{Fe_2O_3}_{(s)}+3CO_{(g)} \rightarrow 2Fe_{(s)} +{3CO_2}_{(g)}\]
Iron (II) oxide \[FeO_{(s)} +CO_{(g)} \rightarrow Fe_{(s)}+{CO_2}_{(g)}\]
Iron (II,III) oxide \[{Fe_3O_4}_{(s)} +4CO_{(g)} \rightarrow 3Fe_{(s)} +4{CO_2}_{(g)}\]

Answer 5

so your answer would be \[3 \times 1.75\]\[1 \times 1.75\]or\[4 \times 1.75 \]respectively
