CHEM 106: Introduction to Chemistry Lab

In this video, we delve into the concept of percent composition by mass, exemplified through the compound chloroform (CHCl?), which was once employed as an inhalation anesthetic despite its associated toxicity. By calculating the percent composition for each element within the compound, we gain valuable insights into its composition and its potential effects on health and properties.

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

Discover the precise KOH volumes to neutralize H?SO? samples with various concentrations. Learn about the acid-base reaction dynamics and stoichiometry.

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

Discover the process of determining a compound's molecular formula from its empirical formula and molar mass. Understand the calculations and reasoning behind deriving C?H? from the empirical formula CH? with a molar mass of 56.11 g/mol. Gain insight into fundamental chemistry concepts and computations.

Join us in this video as we debunk common misconceptions about the periodic table. We explore and clarify statements regarding atomic size, electron configurations, reactivity, and electron removal. Dive into the world of chemistry and gain a deeper understanding of the periodic table's fascinating principles.
