Concept explainers
(a)
Interpretation:
Interpret the following statement is true or false.
‘Freons are member of chlorofluorocarbons’.
Concept Introduction:
Refrigerator releases Chlorofluorocarbon which can also be emitted from air conditioner as well. It contains chlorine and fluorine attached on carbon and also known as Freons. Freons are nontoxic in nature and released from cooling machines. Freons are non flammable and odorless which is used as propellant in air sprays.
(b)
Interpretation:
Interpret the following statement is true or false.
‘Freons used as propellent in sprays to be identified’.

(c)
Interpretation:
Interpret the following statement is true or false.
‘Freons causes destruction of ozone to be identified’.
Concept Introduction:
Exothermic reaction is the reaction for the liberation of energy in a reaction while endothermic reaction takes place with the consumption of energy. Usually the combustion of
Endothermic reaction having +ve dH value while exothermic reaction having −ve dH value.
(d)
