Question

Answer 1

Answer:

Hope this helps you!!

Explanation:

Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.

Answer 2

Below are the methods to identify oxygen and carbon dioxide -

• Oxygen can be identified through burning splinter test. If splint reignites in presence of gas, then it is oxygen.
• Carbon dioxide can be identified through lime water test. If bubbled into lime water solution, carbon dioxide reacts and turns it milky, confirming it's presence.
• They can also be identified through burning candle. Take the gas filled jar and keep burning candle into it. Presence of oxygen will be confirmed if it keeps burning. If it goes out, presence of carbon dioxide is confirmed.
