Classify the following properties of ozones as physical or chemical:
1.bluish color
2.pungent odor
3.reactive towards oxygen
4.decomposes to oxygen on exposure to ultraviolet light
5.it is a gas
Those involving a chemical change are chemical; a physical change is physical. For example, it is a gas; that is a physical property.

To classify the properties of ozone as physical or chemical, we need to understand the difference between physical and chemical properties.
Physical properties describe the characteristics of a substance that can be observed or measured without changing its chemical composition. Chemical properties, on the other hand, describe how a substance interacts with other substances and undergoes chemical reactions.
Now let's classify each property:
1. Bluish color: This is a physical property because it is an observable characteristic of the substance without any change in its chemical composition.
2. Pungent odor: This is also a physical property because it is an observable characteristic of the substance without any change in its chemical composition.
3. Reactive towards oxygen: This is a chemical property because it describes how ozone interacts with oxygen, indicating its ability to undergo a chemical reaction.
4. Decomposes to oxygen on exposure to ultraviolet light: This is a chemical property as it describes a chemical change that ozone undergoes when exposed to ultraviolet light.
5. It is a gas: This is a physical property because it describes the state of the substance without undergoing any chemical change.
So, the properties of ozone can be classified as follows:
Physical properties: Bluish color, pungent odor, it is a gas.
Chemical properties: Reactive towards oxygen, decomposes to oxygen on exposure to ultraviolet light.
