Answer: pressure.

Justification:

1) Pressure is the force exerted by area unit: P = F / S

2) Then, any force applied on a surface exerts pressure.

3) When particles (molecules) collide with the walls of their container, they exert force on the walls, ergo pressure is exerted.

4) The kinetic molecular theory explains the increase of the pressure of the gases resultant of the compression by the fact that the particles are confined to a smaller volumen and so more particles will collide with the walls of the container.

When both –NH2 and –COOH replace hydrogen atoms on the same carbon atom, a(n) ____ is formed. a. amine c. carboxylic acid b. ami

Mice21 [21]

$-NH_{2}$ represents amine functional group and $COOH$ represents carboxylic acid functional group. When these both functional groups are substituted onto a single carbon atom, then amino acid is formed.

The organic compound consists of $-NH_{2}$ functional group and $COOH$ functional group with a side chain is said to be an amino acid.

A: amine group is $-NH_{2}$ .

C: carboxylic acid group is $COOH$

B: amino acid represents $-NH_{2}$ functional group and $COOH$ functional group which are substituted onto a single carbon atom.

D: carbohydrate: the general formula of carbohydrate is $(CH_{2} O)_{x}$ .

Hence, amino acid is the correct answer.

How are radioisotopes used to study chemical reactions?

Natalka [10]

Radioisotopes are used to study chemical reactions because of the fact that they attach radioactive isotopes to certain atoms.<span> Tracer radioisotopes used to study chemical reactions in molecular structures by adding radioistopes to reactants and using the uptake compared to the original isotope. </span>
