3. Which one is part of the kinetic molecular theory? Yes = part of KMT, No = not part
lidiya [134]

Explanation:

a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.

Yes

b. There are no attractive forces and repulsive forces between gas molecules.

Yes

C. Atoms are neither created nor destroyed by ordinary chemical reactions.

No

d. The volume occupied by all of the gas molecules in a container is negligible compared to  the volume of the container

Yes

The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.

According to the theory;

  • The temperature of gas is proportional to the average kinetic energy.
  • Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
  • volume occupied by gases is negligible compared to the volume of the container.

Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

Calculate the number of atoms in 2 mol of sulfur dioxide (SO2).
Alex17521 [72]
Two moles of SO2 means 1.204x10^24 molecules, since there are 3 atoms in one molecule, multiply 1.204 x10^24 by 3 and you get 3.612x10^24.
