Is it a physical change or a chemical change when a reaction occurs, and the product is different from the starting material?
- A Physical change
- B Chemical change
That's Correct!
It's Wrong!
When a reaction occurs and results in products that are different from the original substances, it is a chemical change. In this case, new substances with different chemical properties are formed, which indicates a change in the molecular structure, characteristic of chemical changes. Physical changes, by contrast, do not alter the chemical makeup of the materials involved.
