Final answer:
In the given balanced chemical reaction, 2 moles of CO react with 1 mole of O2 to produce 2 moles of CO2. Thus, 12.0 mol of O2 would produce 24.0 moles of CO, making the correct answer b) 24.0 moles.
Step-by-step explanation:
The student asked: If you had 12.0 mol of O2, how many moles of CO would be produced? The options provided are a) 12.0 moles b) 24.0 moles c) 6.0 moles d) 36.0 moles.
Based on the stoichiometry of the given reaction, the balance equation is 2 CO + O2 → 2 CO2. According to the balanced equation, for every mole of O2, two moles of CO are produced. Therefore, if there are 12.0 mol of O2, this would produce 2 x 12.0 mol of CO, which is 24.0 moles of CO. Hence, the correct answer is b) 24.0 moles.
