It won't. Argon is an element found in the Group 8A also called as the noble gases. They are called as such because they do not react with other elements because their electronic configuration is very stable. This is because they already obey the Octet rule, which has to do with eight electrons occupying around the element. So, it is very rare to have reaction involving any of the noble gases.

Your stomach is a sac-like organ with strong muscular walls. In addition to holding food, it serves as the mixer and grinder of food. Your stomach makes acid and powerful enzymes that break the food down and change it to a liquid or paste. From there, food moves to your small intestine
