Answer:
Explanation:
Gravity:
It is the force by which the elements of matter pulls together.
Explanation:
The gravity is depend upon the mass of matter. The more mass of object the more will be the gravitational force.
The earth is most heavier than all other matter that's why all matter pulls towards the earth.
For example;
when we walk on the earth, it pull us. Our mass is less as compared to the earth that's why we fall back on the earth instead of moving upward because our pull is negligible because of greater difference in masses. The earth mass is very high.
The gravitational force is inversely proportional to the square distance of interacting objects.
As the two objects are more distance apart from each other the less will be the gravitational force.
Well there's a couple reasons why. First, the land itself can become “tired" and less fertile<span>. This is because the same type of </span>crop<span> planted repeatedly in the same area keeps draining the land of the same nutrients needed for that plant's growth. Pest can also plant their nest near the crop if the farmer continues to plant the same crop in the same place.
Which is the reason why things such as "crop rotation" exist to keep things fresh, and prevent what I described above from happening.</span>
Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.
<h3>What is Supernova?</h3>
This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.
The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.
This is therefore the reason why it was chosen as the most appropriate choice.

POH=14-pH
pH=-lg[H⁺]
pOH = 14 + lg0.025 = 12.4
For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
<h3>What is the oxidizing agent?</h3>
In a redox reaction, the oxidizing agent is the one that gains electrons, causing the other element to oxidize.
Let's consider the following redox reaction.
Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq)
The corresponding half-reactions are:
Reduction: 2 e- + Cl₂(aq) ⇒ 2Cl⁻(aq)
Oxidation: 2 Br⁻(aq) ⇒ Br₂(aq) + 2 e-
Which best describes the oxidizing agent in this reaction?
- Bromine (Br) is the oxidizing agent because it gains an electron. NO. Br is the reducing agent.
- Bromine (Br) is the oxidizing agent because it loses an electron. NO. Br is the reducing agent.
- Chlorine (Cl) is the oxidizing agent because it gains an electron. YES.
- Chlorine (Cl) is the oxidizing agent because it loses an electron. NO. Cl gains electrons.
For the reaction Cl₂(aq) + 2 Br⁻(aq) ⇒ 2Cl⁻(aq) + Br₂(aq), Chlorine (Cl) is the oxidizing agent because it gains an electron.
