CHEM 101: Fundamentals of Chemistry I

Understand the fundamental distinctions between pure substances and mixtures. Unpack the definitions and real-world examples of elements, compounds, homogeneous, and heterogeneous mixtures.

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.

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.

Explore the process of determining ionizable hydrogen atoms in malonic acid using its molecular formula C3H4O4 and a neutralization reaction with Sodium hydroxide. Through methodical calculations involving the given mass of malonic acid and the required volume of Sodium hydroxide for neutralization we uncover that each molecule of malonic acid contains two ionizable H atoms.

Discover the difference between strong and weak electrolytes by understanding their ionization in water. Using nitrous acid and nitric acid as examples, this video provides chemical equations that visually distinguish the ionization behavior of these electrolytes.

This video explores the concept of structural levels (primary, secondary, tertiary, and quaternary) in biomolecules, focusing on double-stranded DNA, tRNA, and mRNA to understand the diverse ways these molecules exhibit these structural layers.
