When quicklime is immersed in water, the reaction is:A. ExothermicB. EndothermicC. ExplosiveD. None of these
1 AnswersWhen quicklime (calcium oxide, CaO) is immersed in water, it reacts to form slaked lime (calcium hydroxide, Ca(OH)₂). The reaction is:
\[
\text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{Heat}
\]
This reaction is exothermic because it releases heat. As a result, the temperature of the water increases significantly, and in some cases, steam is produced due to the heat generated.
Thus, the correct answer is:
**A. Exothermic**.
