You can earn a free certificate of completion for this online Chemistry course, or use it to earn credit in leading college programs. 

In our Chemistry course, you will learn to:

  • distinguish between the physical and chemical properties of matter;
  • discuss the law of conservation of mass, the law of definite composition, and the law of multiple proportions; and
  • name ionic and covalent compounds using the rules for nomenclature of inorganic compounds.

Course Introduction:

The ancient Egyptians first identified, studied, and applied chemistry principles to extract metal from ores, make alcoholic beverages, glaze pottery, turn fat into soap, and much more. What began as a quest to build better weapons and create potions capable of ensuring everlasting life became the foundation of modern science. Look around you: chemistry is the science that describes everything you touch, see, and feel, from the shampoo you used this morning to the plastic container that holds your lunch! In this course, we study chemistry from the ground up, beginning with the basics of the atom and its behavior, then progressing to the chemical properties of matter and the chemical changes and reactions that take place all the time in our world.
