When lightning converts oxygen gas O2 into ozone it is a physical change?

When an electrical spark passes through air, it turns some of the oxygen into ozone. Lightning is a big electrical spark. So it is the lightning in the thunderstorm that creates the ozone. Some Swimming Pools in the United States use ozone instead of chlorine to kill the bacteria. Likewise some municipal water systems in Europe use ozone instead of chlorine to kill bacteria. They use sparks to turn the oxygen in air into ozone.

Wiki User
∙ 15y agoLighting breaks apart oxygen molecules (a chemical change), some of which recombine as ozone molecules (O3, an allotrope of oxygen), which is chemically different than oxygen.
Wiki User
∙ 14y agoThe change from oxygen to ozone is best described as a chemical change.
Wiki User
∙ 9y agoNope, that's a chemical change, because the molecule itself is changed. It's not physically reversible.
Wiki User
∙ 9y agoYes. It is a physical change. Oxygen gets converted to ozone.

The chemical change of the sun's energy into glucose and oxygen?
Yea Photosynthesis is the chemical change in plants that uses the sun's energy and converts it into glucose and oxygen.
Is oxygen a chemical change or a physical?
Oxygen is a substance, an element out of the periodic system.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What is the process in which electricity converts oxygen into ozone?
The ozone created by electricity is still ozone.
Is burning alcohol in oxygen a physical or chemical change?
It is a chemical change.
