ANSWER:
The composition of matter always changes when a chemical change takes place.
Step-by-step explanation:
- The matter during a chemical change undergoes a process or reaction that converts the matter into a new element or compound.
- When matter undergoes a chemical change, the state of matter changes and this change is permanent and cannot be reversed.
- This is as opposed to a physical change where the change is reversible one and matter can take back its original form.
