CHEM 111: General Chemistry I

This video provides ground-state electron configurations for various elements, including germanium, iron, zinc, nickel, tungsten, and thallium, based on their atomic numbers.

Discover how to precisely calculate mass, moles, formula units, and atoms in various compounds. Understand the concept with examples like chromium(III) sulfate decahydrate, dichlorine heptoxide, and lithium sulfate. Master chemistry calculations through a step-by-step guide.

This video guides viewers through the process of calculating the volume occupied by Hydrochloric acid gas or HCl at standard temperature and pressure. Using the molar mass of HCl and its properties as an ideal gas the tutorial comprehensively explains each step to determine the volume from a given mass at STP. A must-watch for understanding gas volume conversions in chemistry

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

Discover the simple yet essential method for counting the number of oxygen atoms in different molecular sets, including molecules and ions.

This video discusses how the electronegativity of attached groups affects the strength of acids. Comparing pairs such as Chloroacetic vs Fluoroacetic and Acetic vs Nitroacetic acids, we highlight which is the stronger acid in each pair and why.
