1.	1) A solution of a substance x is used for testing carbon dioxide....
Answer» . i) Substance X is lime water. Ca(OH)2+ CO2→CaCO3+ H2O Ca(OH)2-(Lime water) CO2-(Carbon dioxide) CaCO3-(Calciumcarbonate) H2O -(Water) (ii) Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat. CaO(s) + H2O(l)→Ca(OH)2(ag) CaO(s) -(Quicklime) Ca(OH)2(ag) -(slaked lime) Please like the solution 👍✔️

Answer»

. i) Substance X is lime water.

Ca(OH)2+ CO2→CaCO3+ H2O

Ca(OH)2-(Lime water)

CO2-(Carbon dioxide)

CaCO3-(Calciumcarbonate)

H2O -(Water)

(ii) Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of heat.

CaO(s) + H2O(l)→Ca(OH)2(ag)

CaO(s) -(Quicklime)

Ca(OH)2(ag) -(slaked lime)
