Answer to Question #71843 in General Chemistry for Kosi

Question

What is the limiting reagent from this chemical reaction
2C0 + O2 .......... 2CO2 if we start with 50 grams of CO and 40 grams of O2

Answer 1

Amount of CO: 50 / 28 = 1.785 mol
Amount of O2: 40 / 32 = 1.25 mol
The ratio of reagents for this reaction is 2 : 1,
therefore, CO is the limiting reagent.
