Final answer:
To react 3.2 moles of oxygen gas (O2) to form carbon dioxide (CO2), we need 6.4 moles of carbon monoxide (CO) according to the balanced chemical equation 2 CO + O2 → 2 CO2.
Step-by-step explanation:
To determine the number of moles of carbon monoxide (CO) required to react with 3.2 moles of oxygen gas (O2) to form carbon dioxide (CO2), we should look at the balanced chemical equation for the reaction:
2 CO + O2 → 2 CO2
This equation tells us that two moles of CO react with one mole of O2 to produce two moles of CO2. Since we have 3.2 moles of O2, we can set up a proportion:
(2 moles CO)/(1 mole O2) = (x moles CO)/(3.2 moles O2)
Solving for x gives us:
x = (2 moles CO) * (3.2 moles O2)/(1 mole O2) = 6.4 moles CO
Therefore, we need 6.4 moles of CO to react completely with 3.2 moles of O2 to form CO2.
