Answer:
The correct answer is b) no net energy is involved.
Explanation:
A chemical change, often known as a chemical reaction, is the transformation of one or more compounds into new and distinct substances.
The following is a characteristic of a chemical change:
- It is irreversible.
- The formation of a new material.
- Involves energy absorption or liberation.
- Color Change.
- Production of an odor.
- Change of temperature.
- Evolution of a gas (formation of bubbles).
As a result, The absence of a net energy change is not a characteristic of a chemical transformation.
