General Chemistry 1 & 2

CHM2045/6 - General Chemistry I & II

by: Dr. Stephen Lukacs (August 2020)

General Chemistry is the first course on chemistry for those going into the advanced technical fields, like medicine, engineering, and science. A detailed understanding of the matter and energy of the universe is important to these professions.

Chapter 1

Essential Ideas

(August 2020) The essentials of matter, measurement, units, and computations. This series of lectures present the most critical concepts and practices required for your mastery of general chemistry. It is also critical to lay this as a solid foundation for more advanced, but practical, classes like chemical instrumentation. The topics in this series of Podcasts cover scientific number and notation, significant figures, and conventional conversions, aka, dimensional analysis.

Chapter 2

Atoms, Molecules, and Ions

(August 2020) All chemical elements are composed of the three subatomic particles: neutrons, protons, and electrons. These three particles are in very specific locations and have very specific interactions with each other to makeup the atom or ion. Molecules are a specified collection of atoms or ions bound together to makeup even more complex chemical arrangements.

Chapter 3

Electronic Structure and Periodic Properties of Elements

(September 2020) The historical discoveries leading to quantum mechanics from the nature of waves and the observed periodic properties leading to the shape and form of the Periodic Table come together to yield a cohesive understanding of matter in our entire universe.

Chapter 4

Chemical Bonding and Molecular Geometry

(September 2020) Ever increasing the complexity of the universe, molecules are more than one atom or ion bonding together to create a vast array of compounds with both ionic and covalently bonded configurations.

Chapter 5

Advanced Theories of Bonding

(October 2020) Presents the details of bonding.

Chapter 6

Composition of Substances and Solutions

(October 2020) Everything you've learned prior is about compounds, or substances on the atomic and molecular scale, very small. Now, we scale up to the human scale so that we can mix this substances on a molar level and observe the substances with human eyes and mix them with human hands.

Chapter 7

Stoichiometry of Chemical Reactions

(October 2020) Everything you've learned prior is about compounds and their stability. Now, we get into the meat of chemistry through chemical reactions and the proper amounts and proportions required for good reactions.

Chapter 8


(October 2020) Gases present a unique study of matter for gases have nearly zero intermolecular forces. That allows us to study a list or physical properties of matter.

Chapter 9


(November 2020) Even though chemistry, technically, focuses on matter, its also the interactions of energy with matter. Thermochemistry is that study of interactions of energy with matter, in particular, heat or enthalpy with the transfer of heat into and out of matter and with chemical reactions.

Chapter 10

Liquids and Solids

(November 2020) After covering gases, its important to study the matter that is not condensable, namely, liquids and solids.

Chapter 11

Solutions and Colloids

(November 2020) Let's brew some beer.

Chapter 12


(January 2021) Energy is the driving force of all reactions and chemical processes.

Chapter 13

Fundamental Equilibrium Concepts

(February 2021) What happens when a reaction reverses in on itself?

Chapter 14

Acid-Base Equilibria

(February 2021) Strong and weak acids and bases. Strong doesn't not require equilibria math, but weak definitely do.

Chapter 15

Equilibria of Other Reaction Classes

(February 2021) The more subtle forms of equilibria.

Chapter 16


(February 2021) Much of our modern world works because of electrochemistry.
