A chemical reaction is shown: 2NO(g)+ O₂(g)? 2NO₂(g). How many liters of pure oxygen gas, measured at STP, are required for the complete reaction with 8.82 L of NO(g), also measured at STP?

Question

Quizplus · Accepted Answer

According to the balanced chemical equation, 2 moles of NO react with 1 mole of O2. Therefore, 8.82 L of NO will require half that volume of O2, which is 4.41 L, since gases at STP have a direct volume-to-mole relationship.
