Chemistry Exam-1st Semester (Chapters
1-3)
chemistry - correct answer-study of composition, structure, and properties of matter, the
processes of matter, the process that matter undergoes, and the energy that
accompanies these processes
mass - correct answer-measure of amount of matter
matter - correct answer-anything that has mass and takes up space
atom - correct answer-smallest unit of an element that maintains the chemical identity of
that element
element - correct answer-pure substance that cannot be broken down into simpler,
stable substances and is made of one type of atom
extensive properties
ex) volume, amount of energy, mass - correct answer-depend on amount of matter
present
intensive properties
ex) melting point, boiling point, density, conductivity - correct answer-do not depend on
amount of matter present
chemical reaction - correct answer-change that alters chemical properties
physical reaction - correct answer-change that does not change properties
mixture - correct answer-blend or two or more kinds of substance that can be separated
pure substance - correct answer-fixed composition
homogeneous - correct answer-uniform in composition
heterogeneous - correct answer-not uniform throughout
vertical columns - correct answer-families or groups
horizontal rows - correct answer-periods
