In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of:(a) Cl2 (b) H2 (c) N2 (d) O2
Correct Answer: (c) N2
Explanation: In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of nitrogen as nitrogen is an inert gas and does not react with f fatty acids and oils present in the chips.
