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".

Explain why hydrogen exhibits properties similar to those of both lithium and fluorine?
PtichkaEL [24]

Hydrogen exhibit similar properties with lithium because both are in the same group 1 as they both have a valence electron of 1

  • Hydrogen also exhibit some similar properties with fluorine simply because they are both non metals

<h3>What is an element?</h3>

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, hydrogen exhibit similar properties with lithium because both are in the same group 1 as they both have a valence electron of 1

  • Hydrogen also exhibit some similar properties with fluorine simply because they are both non metals
