Answer:
I think the answer is All of these answers are correct.
The Kinetic Molecular Theory exposes, qualitatively and quantitatively, all the laws that the gas field occupies, which explains that molecules in a gas move rapidly.
The Kinetic Molecular Theory describes the behavior of a gas mass, starting from the behavior of the individual molecules.
- It proposes that the molecules of a gas are in a rapid continuous random movement, which is only altered by the collisions that take place with each other or with the walls of the container.
- All the collisions produced are elastic, that is, the kinetic energy is not modified or altered by said collision.
Therefore, we can conclude that the Kinetic Molecular Theory describes the behavior of gases, and proposes that gas molecules are in constant chaotic motion, colliding elastically with each other rapidly.

In between the two values
Explanation:
Since Calcium is in the same periodic group as both Magnesium and Strontium, the density of calcium will be in between the two values. Calcium, Magnesium and Strontium are all alkali earth metals with two outer electrons.
Calcium is the third element in the group that consists of: Be, Mg, Ca, Sr, Ba and Ra.
- Density is the amount of matter contained in a unit volume of substance.
- Density is directly related to the amount of matter which is the mass of a substance.
- Down a periodic group, the atomic mass increases progressively. The mass of an atom is dictated by the number of protons and neutrons in its nucleus.
- This implies that the density of atoms will increases down a periodic group
- Therefore, it is appropriate to fix the density of calcium between the given values for the two atoms.
