Introduction to Chemistry: Reactions and Ratios

This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical compositions, periodic trends, reactions, and quantitative problem solving will be emphasized with the goal of preparing students for further study in chemistry.

About The Course

This is the first part of a two part introductory course for students with limited or no background in chemistry; in this part of the course, chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized. The goal of the course sequence is to prepare students for further study in chemistry as needed for many science, health, and policy professions. Topics include introductions to atoms, molecules, ions, the periodic table, stoichiometry, and chemical reactions.  The pattern of the use of ratios in chemical problem solving will be emphasized.

Each week the course will contain a series of short video lectures with interactive questions embedded in the lectures. Students will have opportunities to practice each week via exercises at two levels of depth: one set of foundational problems directly related to lecture videos and another set of problems requiring more synthesis of ideas and application of pre-existing algebra skills. Students who complete the course while earning an average of 70% or more on the foundational problem sets and exam will receive a signed statement of accomplishment. Students who complete the course, participate fully in the peer-reviewed writing assignment, and achieve an average of 85% or more on the foundational problem sets, advanced problem sets, and exam will receive a signed statement of accomplishment with distinction.
