Answer:
The determination of the nature of the combination of the two separate materials in the original material that looks pure is based on the characteristic of the change process they undergo to become two separate materials.
Therefore, they can know if they initially had a mixture or a compound by the following steps;
1) If the two separated materials can be easily remixed to form the original material, then they likely have a mixture of the two separate materials
2) If the process that results in the formation of the two separate materials, involves the absorption or evolves heat or other forms of energy, then the original substance was a compound
3) If the two newly formed materials is seen to be a permanent change, then the original material was a compound
Explanation:
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.

Answer: Positive charge
Explanation:
An atom consists of electron (negatively charged), Proton (Positively charged) and neutron (no charge).
The proton (+) and the neutron (no charge) are in the nucleus of the atom. this makes the resulting charge of the nucleus positive while electron (-) is outside the nucleus.
