Kiran lit a candle. she placed a 100cm glass jar over the candle. the candle flame went out after 2 seconds. why did the flame go out

The candle took up all the oxygen under the glass

Explanation:

Carbon dioxide molecules are heavier than air. Because of this, they push the oxygen and other molecules in the air out of the way as they sink down over the flame and candle. When oxygen is pushed away from the wick, it can't react with the wax anymore.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
