Which of the following gases will rekindle a brightly glowing splint?
Answer Details
The gas that will rekindle a brightly glowing splint is oxygen, which is present in N2O (nitrous oxide). When a glowing splint is introduced into a gas that contains oxygen, the oxygen reacts with the glowing ember and reignites the splint. This test is commonly used to identify the presence of oxygen in a gas mixture. Therefore, the correct answer is N2O.
