Which of the following is true of gases?
A. Gases are not easily compressed because of expansion and limited space between particles.
B. Gases mix easily because of their high kinetic energy and low intermolecular forces.
C. Gas particles diffuse easily because of their low fluidity and high intermolecular forces.
D. Gas particles spread out to fill a container because of their high density and high kinetic energy.

B. Gases mix easily because of their high kinetic energy and low intermolecular forces

Explanation:

Gases have higher kinetic energy compared to solid and liquid because the large intermolecular spaces makes a large amount of movement between particles possible. The movements of the particles exhibits kinetic energy.

Gases are highly compressible because its particles aren’t tightly packed together. The intermolecular spaces are large and makes it easier for the gas particles to be compressed in a space which makes option A incorrect.

Gases have Low intermolecular molecules which explains why they aren’t tightly packed together which makes C incorrect.

Gases have a low density because the particles aren’t tightly packed together unlike the solids which are tightly packed together and denser than the liquid and gas which makes option D incorrect

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
