Unit 6: Quantifying Chemical Reactions—Stoichiometry and Moles

scientist_chm

Unit Overview

Elements combine in definite ratios, and the results of a chemical reaction can be predicted using balanced chemical formulas along with careful measurements of the amount of reactants. In this unit, we will explore atomic mass, the limiting reactant (the first reactant to be used up), and the yield of a reaction. Quantification of chemical reactions is key to all the practical applications of chemistry, from developing new energy resources to chemical manufacturing.
