c) carbon dioxide
d) helium

Answer 1

Answer:

carbon-dioxide is the most challenging and problematic factor in the manufacturing of material that controls penetrating.

Answer 2

Controlling penetration of carbon dioxide is the most challenging and problematic factor in the manufacturing of packaging material.

Option (c).

Explanation:

• Because air diminishes the fats present in meats and cheese and turns them pale.

• Now, there could be corrosion from wet carbon dioxide but if provided a carbonate film, it receives some protection and acts fine at higher temperatures too.

• It is used in hydrogen reformer plant systems and oxygen also plays an important role sometimes in amine degradation.

• Carbondioxide is a 'chemical compound' which contain the single carbon atom and two oxygen atom.

• It is referred by the formula $CO_2.$
