Answer 1

The correct answer is Statement-I is true, and Statement-II is false.Key Points

Keeping food in air-tight containers helps to slow down oxidation as it reduces the exposure of the food to air, which is necessary for oxidation to occur.
Chips manufacturers usually flush bags of chips with gas such as nitrogen instead of oxygen to prevent the chips from getting oxidized.
This is because nitrogen is an inert gas and does not react with the chips, thus preventing oxidation.
Statement-I is true as keeping food in air-tight containers does slow down oxidation.
Statement-II is false as chips manufacturers usually flush bags of chips with nitrogen to prevent oxidation, not oxygen.

Additional Information

The loss of electrons by a molecule, atom, or ion during a reaction is called oxidation.
A molecule, atom, or ion undergoes oxidation when its oxidation status increased.
Oxidation is a chemical process in which oxygen reacts with other substances, such as food, and causes a change in their chemical composition.
Air-tight containers prevent the entry of oxygen into the container and thus slow down oxidation.
