In order to prevent the spoilage of potato chips, they are packed inplastic bags containing the gasa) Cl2 b) O2 c) N2d) H2

To prevent the spoilage of potato chips, they are typically packed in plastic bags containing gases that can help preserve their freshness and prevent oxidation.

Explanation of Gas Choices:

1. Chlorine (Cl2): This gas is highly reactive and can be harmful; it is not used for food packaging.
2. Oxygen (O2): While oxygen is essential for life, it also promotes oxidation, which can lead to spoilage and rancidity in food items, including potato chips.
3. Nitrogen (N2): Nitrogen is an inert gas that does not react with the food. It helps to displace oxygen in the packaging, thereby reducing oxidation and prolonging shelf life. This is the most common gas used in packaging potato chips.
4. Hydrogen (H2): Hydrogen is also not used for food packaging due to its flammability and reactivity.

Conclusion:

The best gas among the options provided for packing potato chips to prevent spoilage is c) N2 (Nitrogen). This gas helps maintain freshness by minimizing exposure to oxygen, which can lead to spoilage.
