Ozone is formed when _______.?

How is ozone formed quizlet?

Ozone is formed in the stratosphere by the reaction of ultraviolet radiation striking an oxygen molecule. This results in the oxygen molecule splitting apart and forming atomic oxygen (O2 + hv = O + O). Atomic oxygen can now react with molecular oxygen to form ozone (O+O2 = O3 ).

What is ozone how is it formed and where is it in the atmosphere?

Ozone is a gas that is naturally present in our atmosphere. Throughout the atmosphere, ozone is formed in multistep chemical processes that are initiated by sunlight. In the stratosphere, the process begins with an oxygen molecule (O2 ) being broken apart by ultraviolet radiation from the Sun.

What is ozone how is it formed Class 10?

Ozone layer is naturally found in the upper part of the atmosphere called stratosphere. It is created when ultraviolet radiation (sunlight) strikes the stratosphere, dissociating or splitting oxygen molecules (O2) to atomic oxygen (O). The atomic oxygen quickly combines with further oxygen molecules to form ozone.

Where is ozone formed and stored?

Ozone is produced in the high stratosphere, stored in the lower stratosphere, and destroyed in the troposphere.

Where is good ozone found?

Ozone occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.

Why is ozone layer formed in stratosphere?

Ozone is naturally produced in the stratosphere by a two- step reactive process. In the first step, solar ultraviolet radiation (sunlight) breaks apart an oxygen molecule to form two separate oxygen atoms. In the over- all process, three oxygen molecules plus sunlight react to form two ozone molecules.

How is bad ozone formed?

Bad Ozone. In the Earth’s lower atmosphere, near ground level, ozone is formed when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources react chemically in the presence of sunlight. Ozone at ground level is a harmful air pollutant.

What does ozone smell like?

Here are some of the ways the smell of ozone is described: Like a burning wire. Like chlorine. A “clean” smell. Sweet and pungent.

How bad is ozone for you?

When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.

What is ozone layer class 10th?

“The ozone layer is a region in the earth’s stratosphere that contains high concentrations of ozone and protects the earth from the harmful ultraviolet radiations of the sun.”

Why is ozone important?

The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth’s surface and harming living organisms. UV rays cannot be seen or felt, but they are very powerful and change the chemical structure of molecules.

What is the ozone layer made of?

The ozone layer, also called the stratosphere, is composed of the ozone gas (90% of the total ozone in the atmosphere). The ozone has three oxygen atoms, and it is the result of the action of Ultra Violet (UV) radiation on oxygen molecules, composed of two oxygen atoms.

How is ozone formed by humans?

Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.

How do you detect ozone?

Once inside an instru- ment’s detection chamber, ozone is measured by its absorp- tion of ultraviolet (UV) light or by the electrical current or light produced in a chemical reaction involving ozone.

Is ozone harmful to electronics?

The ozone can damage your electronic equipment. Ozone is highly corrosive, so your system will likely suffer leaks if you expose it to this gas. Purify water and air at the same time: Ozone systems that are designed for water purification in Cincinnati, OH may also work to filter air.
