Ans:-
The reaction of Calcium oxide with water to produce slaked lime releasing a large amount of heat is a combination reaction. Double displacement reactions are the reaction in which there is an exchange of ions between the reactants. Both assertion and reason are true but the reason is not the correct explanation of the assertion. Thus, the correct option is (b).
Explanation:
- When calcium oxide (
) is treated with water, they combine together to form slaked lime (_2%7D%5D)
) and evolve a large amount of heat energy.
- This reaction is called a combination reaction because, in this reaction, two substances react together to form a new compound.
- The reaction is given as:
_2%7D%2BHeat%5D)
