Answer 1

When atoms are rearranged into new molecules, a **chemical change** has occurred. An example of this type of change is the reaction between hydrogen and oxygen to form water. In this reaction, hydrogen gas (H₂) and oxygen gas (O₂) are combined and chemically transformed to create water (H₂O), demonstrating a rearrangement of atoms in the process.
