CHE 427: Organic Chemistry of Biological Molecules

Learn how to calculate the molarity of different solutions containing methanol, calcium chloride, and naphthalene. Essential for chemistry enthusiasts.

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

Explore the fascinating world of intermolecular forces in this brief video, featuring HCl, F?, and C?H?? molecules. Learn about the bonds that hold these substances together!

In this video, we demonstrate the creation of Lewis structures for methane, carbon dioxide, hydrogen selenide, and ammonia, highlighting the arrangement of atoms and bonds in each molecule. The video emphasizes the importance of Lewis structures in visualizing atomic bonding and the presence of lone electron pairs.

This video shows how to determine the number of molecules in a given sample by utilizing the concept of moles, Avogadro's number (6.022 x 10²³), and the molar mass of the substance. It provides step-by-step calculations for different substances, converting mass to the number of molecules and highlighting the versatile application of this approach.

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.
