1 point

Carbondioxide

Nitrogen

Oxygen

Hydrogen

​

Answer 1

Answer:

nitrogen

Chips packets are filled with nitrogen because it is an inert gas, which prevents the oxidation of oils present in chips. So, chips remain fresh.

Explanation:

Potato chip bags are not full of air, but of nitrogen gas.

                          This is done to prevent the chips from oxidizing, which is part of what makes them go stale. Oxygen is very reactive and likes to combine with other molecules whenever it can, causing chemical changes to take place.

                 Nitrogen, however, is very stable and unreactive. A so-called “nitrogen atmosphere” is good for storing foods that oxidize quickly, like potato chips
