Answer:

4.0 moles

Explanation:

Based on the given reaction between carbon and hydrogen, the equation of the reaction between O₂ and CO is as follows:

2CO(g) + O₂(g) → 2CO₂(g)    

The number of moles of O₂ needed to completely react with 8.0 moles of CO can be calculated knowing that 2 moles of CO react with 1 mol of O₂:

[tex] n_{O_{2}} = \frac{1 mol O_{2}}{2 moles CO}*8.0 moles CO = 4.0 moles O_{2} [/tex]

   

Therefore, the number of moles of O₂ needed is 4.0.

I hope it helps you!
