One example of a useful chemical change is the combustion of gasoline in a car engine.
When gasoline is burned in the presence of oxygen, it undergoes a chemical reaction that produces energy, water, and carbon dioxide. This reaction is a chemical change because the original molecules of gasoline and oxygen are broken apart and rearranged to form new molecules of water and carbon dioxide.
The energy released during this reaction is used to power the engine and move the car. Without this chemical reaction, the car would not be able to function. Therefore, this chemical change is extremely useful in our daily lives as it allows us to travel long distances quickly and efficiently.
