CHM 171: CHM 171 Workshop

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.

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

Discover the contrasting processes of vaporization and condensation and their thermal nature. Understand why boiling is endothermic, absorbing heat, while condensation is exothermic, releasing heat, and how these processes impact ?H values.

This video focuses on unit conversions and the practical use of conversion factors to translate quantities between different units. It provides clear examples of converting 70 kilograms to pounds, translating 14 billion years into seconds, changing the height of a basketball player from feet and inches to meters, and converting cubic meters to liters, illustrating the importance of this skill in various scientific and everyday scenarios.

Unravel the science behind endothermic and exothermic processes by studying vaporization and condensation. Grasp the molecular changes involved and understand the role of heat in these transformations. A comprehensive look into why vaporization requires heat, while condensation releases it.
