Unit 4: Chemical Formulas and Equations
Chemists need to write out formulas and equations to solve chemistry problems. In this unit, we begin to name and write compounds and learn how 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, what volume of steam created if we turn one kilogram of ice into pure steam, at 200o Celsius and sea-level air pressure? We can calculate the precise answer when we write the reaction out in the form of an equation!
Completing this unit should take you approximately 6 hours.
