Unit 4: Chemical Formulas and Equations
We will now introduce the major tool you will need when solving chemistry problems: the ability to write out formulas and equations. In this unit, you will build upon your understanding of molecules and bonding and begin to name and write compounds. We will then learn to write out and balance chemical equations. Equations enable us to describe chemistry topics in mathematical terms and predict the outcomes of reactions. For example, if we turn 1 kilogram of ice into pure steam at 200 Celsius and sea-level air pressure, what is the volume of steam created? Writing the reaction out in the form of an equation will allow us to precisely calculate the answer!
Completing this unit should take you approximately 9 hours.
