Question

the following list contains several properties of ozone (a pollutant in the lower atmosphere but part of a protective shield against uv light in the upper atmosphere). which are physical and which are chemical? drag the appropriate items to their respective bins. reset help pungent odor very reactive gas at room temperature bluish color decomposes on exposure to ultraviolet light physical chemical

Explanation:

• Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition.
• "Pungent odor" is a physical property as it can be detected by the sense of smell without altering ozone's chemical structure.
• "Gas at room temperature" describes the state of ozone under normal conditions, which is a physical property.
• "Bluish color" is a visual characteristic, a physical property.
• Chemical properties describe how a substance reacts or changes into other substances.
• "Very reactive" indicates ozone's tendency to undergo chemical reactions.
• "Decomposes on exposure to ultraviolet light" shows a chemical change (decomposition) of ozone, so it is a chemical property.

Answer:

• Physical: pungent odor, gas at room temperature, bluish color
• Chemical: very reactive, decomposes on exposure to ultraviolet light
