What happens when we pass co2 through lime water for a long period of time.
why

➷ The limewater will turn cloudy/milky. This is because this reaction causes the insoluble calcium carbonate to form. As it is insoluble, it turns the solution cloudy. (this would happen if it was a short time.) Over a longer period of time, the solution would turn clear again. This is because a salt called calcium hydrogen carbonate is formed from the calcium carbonate. This salt is soluble and would dissolve, causing it to turn clear again.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
