Identify the type of reaction in the following experiment:

(I) Combination Reaction
(II) Decomposition Reaction
(III) Exothermic Reaction
(IV) Endothermic Reaction

Options

A. Only (I)
B. Only (II)
C. Both (I) and (III)
D. Both (II) and (IV)

Answer

C

Explanation

The reaction between calcium oxide and wateris combination reaction as the two compounds combine to from a single product slaked lime , `Ca(OH)_(2)` and the equation of the reaction taking place is :
`CaO_((s))+H_(2)O_((i))toCa(OH)_(2(aq))+`Heat
It is also an exothermic reactionas large amount of heat is released during this reaction .
