SEMESTER EXAM REVIEW MRS STAFFORD HS PHYSICAL SCIENCE

WHAT IS THE DIFFERENCE BETWEEN A MIXTURE AND PURE SUBSTANCES MATTER CAN BE BROKEN DOWN INTO TWO CATEGORIES: PURE SUBSTANCES AND MIXTURES. PURE SUBSTANCES ARE FURTHER BROKEN DOWN INTO ELEMENTS AND COMPOUNDS. MIXTURES ARE PHYSICALLY COMBINED STRUCTURES THAT CAN BE SEPARATED INTO THEIR ORIGINAL COMPONENTS. A CHEMICAL SUBSTANCE IS COMPOSED OF ONE TYPE OF ATOM OR MOLECULE.
