t physiological pH, the carboxylic acid group of an amino acid will be ________, while the amino group will be ________, yieldin
astraxan [27]

Answer:

At physiological pH,the carboxylic acid group of an amino acid will be deprotonated while the amino group will be protonated,yielding the zwitter ion form.

Explanation:

Deprotonated means removal of protons in an acid base reaction and protonated means addition of protons in an acid base reaction.

Both protonated and de protonated reaction takes place in catalytic acid bade reaction by changing either it's mass or it's charge.

During formation of zwitter ion, the carboxylic acid will be deprotonated by donating the H+ ion while the amino acid is protonated by taking the H+ ion.

When you squeeze an air-filled balloon, what happens inside?
Harman [31]

Option D

When you squeeze an air-filled balloon, what happens inside: There are more collisions of air molecules against the wall of the balloon.

<u>Explanation:</u>

If you compress off the balloon, one seemingly sense the air forcing up on the wall of the balloon with indeed more imposing power. This rise in force is due to a drop in quantity. By squeezing the balloon, you lessen the area the gas bits can hold.

As the particles are driven a little closer collectively, they oppose more, so the force from the moving gas bits rises.  Boyle’s Law pronounces that the quantity of a determined quantity of gas limits as its load rises. If the quantity rises, its load reduces.
