CHEM 2444: Organic Chemistry

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.

Explore the calculations for mole fractions, partial pressures, and total pressure in a 22.4 dm³ vessel with H? and N? at 273.15 K.

In this chemistry tutorial learn how to calculate the molar mass of various compounds using atomic masses from the periodic table. Discover the molar mass for compounds such as Strontium Hydroxide Dinitrogen Trioxide Sodium Chlorate and Chromium(III) Oxide. A concise guide to understanding molar masses and their real-world applications.

Discover how to craft balanced, complete ionic, and net ionic equations for various chemical reactions. Learn the significance of aqueous ions and solid state indicators in these equations.

This video breaks down the configurations for In In+ In2+ and In3+ distinguishing between diamagnetic and paramagnetic properties. Uncover the oxidation state of Indium in InCl2 and understand its diamagnetic nature.

This instructional video guides you through the process of determining the number of molecules in a given sample. It illustrates the conversion from grams to moles using the molar mass of the substance and then to molecules using Avogadro's number, providing a practical example with ethane (C?H?) to calculate approximately 6.67 x 10²¹ molecules in a 0.334 g sample.
