All of the following are examples of chemical properties except All of the following are examples of chemical properties except the rusting of an iron nail left out in the rain. the ability of a drain opener to unclog a drain using sodium hydroxide. the low pH of stomach acid. heat being given off by the burning of natural gas in a kitchen stove. chlorophyll being responsible for the green color of leaves.

Answer: Option (d) is the correct answer.

Explanation:

A property that does not bring any change in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical properties.

Also, chlorophyll being responsible for the green color of leaves is a physical property because occurrence of green color in plants is due to physical spectra which is a physical property.

Whereas a property that changes chemical composition of a substance is known as chemical property.

For example, precipitation, reactivity, toxicity etc are chemical property.

A chemical change cannot be reverted back. So, rusting of iron nail, ability of a drain opener to unclog a drain using sodium hydroxide, the low pH of stomach acid, heat being given off by the burning of natural gas in a kitchen stove are all chemical changes.

Thus, we can conclude that all of the following given statements are examples of chemical properties except change chlorophyll being responsible for the green color of leaves.
