Which statement is part of kinetic molecular theory
a gas particles are in constant motion
b gas particles attract each other
c gas particles lose their energy during collisions
d gas particles stick to the walls of their container

A. Gas particles are in constant motion.

Step-by-step explanation:

The first postulate of Kinetic Molecular Theory is that gas particles are in constant motion.

B is wrong. Kinetic Molecular Theory assumes that there are no attractive forces between the molecules.

C is wrong. Kinetic Molecular Theory assumes that collisions between molecules are elastic.

D is wrong. Kinetic Molecular Theory assumes that there are no attractive forces between the molecules of the gas and those of its container.

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

the answer is option a.
