CHEM 88620: General Chemistry 1035

Learn the steps to make a 2.5 L of 0.100 M KCl solution from a 5.5 M stock solution in this easy-to-follow tutorial.

Explore the conductivity of aqueous solutions: Cesium bromide and hydrogen iodide. Understand their ionic nature and how it leads to the presence of charged ions enabling electricity conduction

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole

Explore the environmental impact of sulfur dioxide production, revealing how 26 million tons of this compound conceal 13 million tons of sulfur. It delves into the chemistry of this transformation, converting atomic and molecular masses, providing valuable insights into emissions from activities like burning coal and auto exhaust."
