CHEM 122A: General Chemistry II

Master metric unit conversions with step-by-step examples, including cm to meters, g to kilograms, cm to millimeters, and mL to liters.

Explore the classification of select molecules based on their polarity. Understand the electron distribution and molecular shapes of Formaldehyde, Methanol, Dichloromethane, and Carbon dioxide. Discover which ones exhibit a net dipole moment and which ones don't.

Explore the polarity of Carbon disulfide, Sulfur dioxide, Methane, and Chloromethane. Learn how molecular shape influences electron distribution. Understand which molecules possess a net dipole moment and which ones don't.

We explore synthesis and decomposition reactions, showcasing examples like the formation of water and its breakdown into simpler substances. We also clarify that while many of these reactions are redox reactions involving electron transfer, some synthesis and decomposition reactions may not necessarily be redox reactions, as seen in specific examples.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

Learn how to create Lewis structures for various molecules and assign charges where needed. Understand the molecular connectivity and electron distribution.
