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.

Explain how scientific advancements have lessened the effects of hazardous events on society.

Answers

Answer:

Scientific advancements can detect some harmful events before they occur and it allows the society to plan for them, thereby reducing the risk of damage that occurs.

Explanation:

Scientific advancements reduce the natural disasters level in a region by evaluating the physical and chemical characteristics of the land.

Also, it develops new medical terminology and concepts that reduce the spread of hazardous diseases in society.

Satellites are used to predict the weather report and by using this report proper precautions can be taken at the time of floods and storms.

Construction of dams and canals highly reduced the risk of water overflowing in the lands.

Answer: Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.

What kinds of scientific investigations involve making observations?

Answers

1. Coherence Theory (Theory of Coherence)

Based on this theory, a knowledge considered to be true if the knowledge kehoren with the knowledge that exists and has been proven to be true. In the study of mathematics this is usually called the deductive nature.

2. Correspondence Theory (Theory of corespondence)

Based on this theory, a knowledge considered to be true if the knowledge of having a relationship with a reality that is true. This theory is based on the empirical fact that knowledge is true if there are facts that support that is true knowledge. Thus the truth here is based on inductive inference.

3. Pragmatic Theory (Theory of Pragmatism)

According to this theory, knowledge is said to be true if the knowledge is seen practically completely or have properties that true practicality. Followers of this theory argue that knowledge is true if it has keguanaan practical.

What was Newtons first law

Answers

Newton's first law is inertia. It is a law that you see in regular life. It states that a object that is still will stay still except for if a force acts on it. The law also states that a object in motion will continue at the same velocity except for if a force acts on it. The thing is that objects in motion are being slowed down by friction and air resistance and gravity

It states that each object will stay very still or in uniform movement in a straight line unless constrained to change its state by the activity of an outer power.

HURRY PLEASE!!! The hydrogenation of unsaturated hydrocarbons isan important industrial process. Precious metals,
such as platinum and palladium, can greatly
increase the rate of this reaction. During this
process, the gaseous reactants are pumped
across a layer of metal powder. An example of this
process is shown below.
Describe how the metal probably increases the
reaction rate, identify whether this is an example of
homogeneous or heterogeneous catalysis, and
explain how you know.

Answers

A reducible molecule undergoes hydrogenation when hydrogen is added to it. Alkenes, alkynes, and aromatic molecules that are unsaturated are converted into saturated products through the hydrogenation of hydrocarbons.

What is hydrogenation ?

A chemical reaction known as hydrogenation occurs when molecular hydrogen interacts with another substance or element, typically in the presence of a catalyst made of nickel, palladium, or platinum. The method is frequently used to saturate or decrease organic molecules.

With the aid of nickel or palladium catalysts, unsaturated hydrocarbons are added to hydrogen in this process to create saturated hydrocarbons. Example: Applying an addition reaction to ethane in the presence of catalysts like nickel or palladium allows for the conversion of ethane.

When making plastics, unsaturated hydrocarbons are incredibly helpful organic substances. Egg cartons, disposable cups, and other practical things are made of polystyrene. Alkenes are utilized in the production of industrial compounds like alcohol.

Thus, A reducible molecule undergoes hydrogenation when hydrogen is added to it.

Answer: The metal probably increases reaction rate by either holding reactant molecules in the correct orientation to react or by weakening or breaking bonds in reactant molecules to make them more reactive. This is an example of heterogeneous catalysis.

Explanation: It is heterogeneous catalysis because the catalyst is a solid and the reactants are gases. In heterogeneous catalysis, the catalyst is in a different phase than the reactants.
