CHM 132: General Chemistry II

When water boils, bubbles rise to the surface, but what's in these bubbles? Let's evaluate the options. Option d, water vapor, is correct; the bubbles during boiling are primarily composed of water vapor, the gaseous state of water.

This video elucidates the method to sketch Lewis structures for the radical species ClF? and BrO?. Highlighting the distinguishing feature of an unpaired electron, we illustrate the bond arrangements and lone pairs that define these unique chemical entities.

Unravel the Lewis structures of BrF?, ClF?, and IF? and their relationship with the octet rule. Examine how fluorine bonds with bromine, chlorine, and iodine. Identify molecules that deviate from the standard octet distribution.

Learn how to write nuclear equations for positron emission with Co-55, Na-22, and F-18. Explore the fascinating world of nuclear reactions.

Delve into the intricate interplay between glycogen synthesis activation and glycogen phosphorylase deactivation. Discover the essential mechanisms that ensure the efficient management of glucose storage and utilization in the body.

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.
