Which one of the following statements is correct?A. An electron has a negative electrical charge.
B. An electron has a neutral electrical charge.
C. An electron is much larger than an atom.
D. An electron is located inside the nucleus of an atom.

Answers

Answer: Option (A) is the correct answer.

Explanation:

An atom consists of three sub atomic particles. These particles are protons, electrons and neutrons.

Protons have a positive charge. Whereas neutrons have no charge. On the other hand, electrons have a negative charge.

Thus, we can conclude that out of the given options, an electron has a negative electrical charge is the correct statement.

When magnesium is added to hydrochloric acid, a gas is formed. Explain what happens in the reaction, how the gas is collected and how it could be tested to prove what it is.

Answers

Answer:

Explained below.

Explanation:

Formula when magnesium reacts with hydrochloric acid is given by;

Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)

So, from the equation, we can see that the gas formed is hydrogen.

This hydrogen gas is collected by a method known as water displacement.

This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.

The force of attraction that the earth exerts on all objects is called

Answers

The force of attraction that the earth exerts on all objects is called gravitational force. The gravitational force is the force that has the property of attracting any object having a mass. Without this gravitational force it would not have been possible for anything to remain on earth. Everything would start floating without the gravitational pull of earth. There are actually four kind of forces that are considered in physics. They are the strong force, weak force, gravitational force and the electromagnetic force. It is absolutely true that every object is pulling other objects due to the forces present in nature.
