Answer:
4.0 moles
Explanation:
Based on the given reaction between carbon and hydrogen, the equation of the reaction between Oâ‚‚ and CO is as follows:
2CO(g) + Oâ‚‚(g) → 2COâ‚‚(g)  Â
The number of moles of Oâ‚‚ needed to completely react with 8.0 moles of CO can be calculated knowing that 2 moles of CO react with 1 mol of Oâ‚‚:
[tex] n_{O_{2}} = \frac{1 mol O_{2}}{2 moles CO}*8.0 moles CO = 4.0 moles O_{2} [/tex]
 Â
Therefore, the number of moles of Oâ‚‚ needed is 4.0.
