Question

When atoms are rearranged into new molecules a chemical/physical change has occured an example of this type of change is (choose a commonly known one)

Answer 1

An example of a chemical change is the combustion of gasoline in an engine. When gasoline (a hydrocarbon) burns, it reacts with oxygen to produce carbon dioxide and water. This process involves the rearrangement of atoms and the breaking and forming of chemical bonds, resulting in new substances that are different from the original reactants.
