Answer 1

Answer:

Explanation:

Quick lime reacts vigorously with water to produce slaked lime releasing a large amount of heat. So the reaction is highly exothermic.

                                                                                                                                                     

Slaked lime is only slightly soluble in water, so it forms a suspension of slaked lime in water.

The clear solution obtained after the suspension settles is called lime water.

Exhaled air contains CO2 which turns lime water milky.

Calcium oxide and water react to form only a single product, calcium hydroxide. So the reaction is a combination reaction.
