Why do the particles of objects have both kinetic and potential energy?

Answers

The particles of objects have both kinetic and potential energy because these forces are drive by the force of motion or stillness of an object. Potential energy is the a type of energy which an object possess however without motion. Kinetic energy in the other hand, is the energy in motion or if the object moves along from one space to another with respect to time. They both have these two energies by the presence of atoms in these entities.

What compound is O2H?

Answers

The answer is:

O2H is a reactive oxygen species (ROS).

The explanation is:

It is known by different chemical names like:

- Dioxidanide, Oxylatooxygen, HOO anion, hydroperoxyl, Hydrogen dioxide (1-), Hydrogen peroxide (1-), etc.

- ROS show antimicrobial activity, so they can be used as antibiotics.

- O2H is also manufactured as a bacteriostatic antibiotic.

-It is generally available in tablet form.

- It is used in the treatment of many gram-positive and gram-negative bacterial infections, like infections of the skin, eye, lungs (bronchitis), urinary tract, bladder, pelvis, etc. (Note: A bacteriostatic antibiotic is one which damages bacterial DNA. Bacterial replication is hindered, so bacterial infection is combatted).

Answer:

O₂H is Reactive Oxygen Species (ROS)

Explanation:

O₂H has many names including:

1- hydroperoxyl

2- Oxylatooxygen

3- Dioxidanide

4- Hydrogen dioxide or Hydrogen peroxide

This compound exists in stable form only in the aqueous state and is formed by the equation shown in the attached picture.

This compound is used mainly in the manufacture of bacteriostatic antibiotics. This is because it can damage the DNA of the bacteria which leads to the termination of its replication and thus, it can be combated.

Hope this helps :)
