What happens to the gravitational force between two objects as the distance between them decreases?
Harlamova29_29 [7]

Answer:

gravitational force increases

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are brought closer to each other, the force of gravitational attraction between them also increases.

The statement that best describes the types of bonds shown in the diagram is a covalent bond; the hydrogen atom’s single electron is being shared with the chlorine atom, therefore the correct answer is the option B

<h3>What is a covalent bond?</h3>

When two similar or dissimilar atoms form bonds with each other by sharing their valence electron the bond is known as the covalent bond.

The ionic bond is the result of the transfer of the electrons

Ionic bonds are formed between the pair of one electronegative atom and an electropositive atom.

As shown in the diagram there is sharing of the electrons between the hydrogen and the chlorine atom, and we know that covalent bonds are formed by the sharing of the electrons

Since the diagram's covalent bonds are best described by the statement that the hydrogen atom's single electron is shared with the chlorine atom, option B is the right response.
