In this video lesson, we explored the fundamental principles governing chemical combination, laying the groundwork for understanding chemical reactions.

Learning Objectives:

By the end of this video lesson, the students should be able to:
1. explain what a law is,
2. mention and explain the four laws of chemical combination
3. solve problems associated with chemical combination,
4. differentiate between symbols and formula
5. define and differentiate between the three formulas we have,
6. Solve problems associated with Empirical and molecular formula,
7. define what stoichiometry is and balance chemical equations of chemical reactions
8. define and calculate relative atomic masses based on Carbon-12, and
9. explain the mole concept and the Avogadro number.
