CHEM 357: Biochemistry II

Learn the art of precise chemical calculations in this video. Discover how Chromium(III) oxide reacts with hydrogen sulfide to form chromium(III) sulfide and water, all while unraveling the necessary steps to determine the exact quantities involved.

Explore the power of chemical names and symbols in deciphering copper compound formation at each step of the copper cycle, with an illustrative example.

Learn how to create Lewis structures for various molecules and assign charges where needed. Understand the molecular connectivity and electron distribution.

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.

Explore how to calculate the mass and volume of ethylene glycol, a common antifreeze, using its density. Understand the essentials of density-related calculations.

This video explores molar concentration (molarity) and demonstrates the calculation of oxygen's molar concentration in water at 25°C, considering a partial pressure of 0.22 atm by employing Henry's Law and the given Henry's Law constant for oxygen, revealing that under these conditions, there are 2.86 x 10?? moles of oxygen per liter of water, highlighting the significance of understanding these concepts for managing gas dissolution in liquids across varying circumstances.
