Question

a candle burns in the absence of oxygen. true or false. who tell answer i will brainlist him​

Answer 1

Answer:

False

Explanation:

A candle burns in a jar of oxygen as it is a supporter of combustion i.e hydrocarbons in the presence of oxygen form carbon dioxide water and heat,  but is extinguished in nitrogen, as it does not support combustion due to its triple bond.

Answer 2

False, a candle can't burn in the absence of oxygen.

Explanation:

• A lit candle needs oxygen to burn. It takes oxygen from the air in order to continue burning. If we limit the amount of oxygen available, the candle's flame eventually stops burning once it uses up all the oxygen available.
• Oxygen is needed for combustion and no other gas can be used in place of oxygen and hence, the candle can't burn in the absence of oxygen.
