Chemistry is the study of matter, energy, and their interactions. Matter is everything around you and
in the universe, so chemistry helps you understand your immediate world and the universe. In this
course, you’ll learn about the composition of matter from the subatomic level to the molecular level
to the macroscopic level. You’ll see how the same building blocks can be rearranged to form countless
substances. This course will help you predict properties of different substances and the reactions that
they undergo.
