CHEM 199: Undergraduate Open Seminar

Discover the process of naming acids based on their anions and oxidation states. This video breaks down the correct naming of HNO2(aq) by distinguishing its anion and determining its place in the world of mineral acids.

Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.

Converting Denver's average pressure of 24.9 in. Hg into various units. This video provides clear steps to determine equivalents in millimeters of mercury atmospheres pounds per square inch and pascals. Understand the relationships and conversions between these common pressure units.

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.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.

Understand the relationship between atomic number, mass number, and neutrons within atoms. This video breaks down the simple calculation to determine the number of neutrons for specific elements like Nickel, Uranium, Scandium, and Argon.
