Hii dear,
You didn't post the concerned image, but I'll try my best to answer this.
● Answers -
(1) Gas passed through limewater is CO2.
(2) Limewater turns cloudy in appearance.
(3) Equation : Ca(OH)2 + CO2 -> CaCO3 + H2O
● Explanation -
Lime water is prepared by adding quicklime to water.
CaO + H2O --> Ca(OH)2
When CO2 is passed through lime water, white precipitate of calcium carbonate is formed that makes limewater cloudy in appearance.
Ca(OH)2 + CO2 --> CaCO3 + H2O
Thanks for asking..
