CHEM 111: Principles of Chemistry I

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.

This video discusses the process of writing chemical formulas for different compounds, providing details on the types and charges of ions involved in each compound's composition. The video concludes with the chemical formulas for barium hydroxide, magnesium sulfite, calcium carbonate, ammonium sulfate, and lithium hydrogen carbonate.

Examine the nature of bonds in methylamine, ethane, fluoromethane, and methanol. Identify ethane's nonpolar covalent bond and understand why fluoromethane's bond leans toward the ionic spectrum. Grasp essential concepts in molecular bonding with this deep analysis.

This video guides you through calculating the theoretical yield of a product in moles for a given chemical reaction by identifying the limiting reactant. It explains how to determine the limiting reactant for different quantities of reactants and then calculates the corresponding moles of the product, ensuring an accurate theoretical yield estimation.

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.
