Question

Which gives co2 on heating slaked lime or limestone?

Answer 1

slaked lime will give co2

Answer 2

Answer:

Lime stone on heating gives carbon dioxide gas.

Explanation:

Slake lime that calcium hydroxide on heating gives calcium oxide and water.

$Ca(OH)_2(s)\overset{heat}\rightarrow CaO(s)+H_2O(g)$

According to reaction , 1 mole of calcium hydroxide on heating gives 1 mole of calcium oxide and 1 mole of water vapors.

Lime stone that id calcium carbonate on heating give calcium oxide and carbon dioxide gas.

$CaCO_3(s)\overset{heat}\rightarrow CaO(s)+CO_2(g)$

According to reaction , 1 mole of calcium carbonate on heating gives 1 mole of calcium oxide and 1 mole of carbon dioxide.
