What is relativity exactly

The most reactive element among the options is iodine. The Option A.

Why is iodine the most reactive?

Iodine is the most reactive element in this list because it belongs to the halogen group of elements in the periodic table, which is known for its high reactivity.

Halogens readily form compounds by gaining electrons to achieve a full outer electron shell. Iodine, with its seven valence electrons has a strong tendency to gain one more electron to achieve stability.

This makes it highly reactive especially when it comes into contact with elements that readily lose electrons such as metals.

Answer:

iodine

Explanation:

A is obiviously the answer here.

Answer:

its b watch

Explanation:

They already know the distance if they know the time then they can find their speed. For example Mph is miles per HOUR therefore all they need is distance and time

Answer: The correct answer is Option A.

Explanation:

In a chemical equation, the chemical species are termed as reactants or products.

Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.

For the given chemical equation:

The chemical species written on the left side of the arrow are . They are considered as reactants.

The chemical species written on the right side of the arrow are . They are considered as products

Hence, the correct answer is Option A.

A particle diagram showing the composition of air would represent various gases like nitrogen, oxygen, water vapor, and carbon dioxide as spheres of different colors. The proportions between these gases would be shown by having a majority of nitrogen and oxygen spheres as they make up most of our atmosphere. The diagram may also include symbols for dust particles and particulate matter.

A particle diagram to illustrate the composition of air would visually represent the mixture of gases that comprise our atmosphere. Primarily, the atmospheric mix includes nitrogen (N₂; 78.6 percent), oxygen (O₂; 20.9 percent), water vapor (H₂O; 0.5 percent), and carbon dioxide (CO₂; 0.04 percent).

Each of these gases exist as molecules, with nitrogen and oxygen being diatomic. In other words, their molecules consist of two atoms.

In such a diagram, each type of atom would be represented as a sphere of a different color, for instance, nitrogen atoms might be blue, oxygen red, hydrogen white, and carbon grey.

The proportions would be represented by having a larger number of nitrogen and oxygen spheres compared to water vapor and carbon dioxide.

Furthermore, there might be additional entities in the diagram to represent dust particles or other environmental particulate matter suspended in the air. This allows us to get a qualitative understanding of the composition of Earth's atmosphere and mechanisms that drive gas exchange.
