CHEM 2304: Organic Chemistry II for the Life Sciences

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

Discover the importance of calculating percent error to assess the precision of experiments. Through real-world examples like measuring alcohol's density and the mass of gold, learn how this value offers insights into measurement accuracy and ways to refine methods.

Explore the process of determining ionizable hydrogen atoms in malonic acid using its molecular formula C3H4O4 and a neutralization reaction with Sodium hydroxide. Through methodical calculations involving the given mass of malonic acid and the required volume of Sodium hydroxide for neutralization we uncover that each molecule of malonic acid contains two ionizable H atoms.

This video tackles the classification of boiling water as either a physical or chemical change, examining the provided options. We conclude that boiling is a physical change, as the water's chemical composition remains the same during the transition from liquid to gas.

This discussion revolves around the classification of chemical bonds as ionic, polar covalent, or covalent based on the electronegativity difference between the atoms involved. The general criteria for this classification are explained: a difference greater than 1.7 indicates an ionic bond, between 0.5 and 1.7 signifies a polar covalent bond, and less than 0.5 designates a covalent bond. It then applies these criteria to four specific examples, including the CC bond in ethane (H?CCH?), the KI bo

The video offers an insightful look into the orthorhombic unit cell, a unique crystal lattice structure. By exploring nickel sulfate's unit cell and its specific dimensions, we determine both the number of formula units and the density of this crystalline structure.
