What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Can you name two chemical changes?
Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
What are two ways that chemical weathering changes rocks?

Are chemical changes when substances combine or are they when substances breaking apart?
