Question

John lit a candle and kept it in a beaker. He covered the beaker with aluminium foil to cut off the air supply. When the candle extinguished he put a little lime water in the beaker and swirled it.
a. What will he observe?
b. Support you answer with a reason.

Answer 1

Answer:

lime water will turn milky because candle uses all the oxygen and converted it to CO2. and he cut off air supply so that new oxygen is not able to get in. so there will be only CO2
