Answer 1

Chemical change

Step-by-step explanation:

If two types of matter reacts or are combined and energy is given off, the type of change that might have occurred is a chemical change. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible. When an exothermic reaction or change occurs, heat is released and it is a typical characteristic of chemical change.
