The following videos are brought to you by ALTC peer educators Arielle Morris, Ellie Young, and Ashlyn Driskell.

Episode 1: Introduction to Gen Chem I

Episode 2: Basics of Chemistry

In this video, in this order, I give a general understanding of significant figures, I discuss sig figs with the addition and subtraction rule, then with the multiplication and division rule. After that, I go into SI units, followed by matter and its classifications. Then, I talk about unit conversions and important equations. From 7:45 to the end, I go over 2 practice problems that involve measurements and conversions, incorporating unit conversions, equations, and significant figure rules.

Episode 3: Limiting Reactants

Limiting Reactants In this video, I describe an overview of how I like to approach limiting reactants (from 0:10 to 1:42), and the rest of the video is a step by step limiting reactant practice problem!

Episode 4: Percent Yield (and Limiting Reactants)

In this video, I describe an overview of percent yield (from 0:20 to 1:25), and the rest of the video is a step by step percent yield practice problem, which also applies the concept of limiting reactants!

Episode 5: Periodic Table Trends

I discuss periodic trends in the following order: atomic radius/size/polarizability; ionization energy and electron affinity; nonmetallic character and metallic character.

Episode 6: Resonance Structures, Formal Charges and Lewis Structures

In this video, I go over resonance, formal charge, an example with resonance and formal charges, and then an example with Lewis structures that ties all of the concepts together.

Episode 7: VSEPR Notation

In this video, I discuss Hybridization, give an overview of generic formulas, and then go over all of the important information for 1 Domain, 2 Domains, 3 Domains, 4 Domains, 5 Domains, & 6 Domains. This information includes: bond angles, electron geometry, molecularly geometry or geometries, generic formula types, examples, and visuals of the formulas and examples. I also give many tips and tricks on how to go about these types of questions throughout the video!
