Question

A small amount of quick lime is added to water in a beaker. A)name and define the type of reaction that has taken place. B)write balanced chemical equation for the above reaction.write the chemical name of prodect obtained. C)state two observations that you will make in this reaction

Answer 1

Answer: a. The combination/addition reaction and exothermic reaction will take place.

Combination Reaction : The reaction in which two or more compounds add to form a single compound is known as Combination Reaction .

Exothermic Reaction : The reaction in which heat is released is known as Exothermic Reaction .

b. CaO + H₂O ⇒ Ca(OH)₂ + Heat ↑

c. Calcium oxide (quick lime) will react vigorously with water and form (slaked lime) Calciumhydroide.

As we know, It is exothermic reaction. It'll be produce heat during reaction.
