CHEM 120: General Chemistry

Learn how to write nuclear equations for positron emission with Co-55, Na-22, and F-18. Explore the fascinating world of nuclear reactions.

This video elucidates the method to sketch Lewis structures for the radical species ClF? and BrO?. Highlighting the distinguishing feature of an unpaired electron, we illustrate the bond arrangements and lone pairs that define these unique chemical entities.

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.

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

Explore the concept of the degree of unsaturation in hydrocarbons. Understand its importance in revealing double bonds, triple bonds, or rings. Learn through examples like limonene, squalene, and lycopene.

Learn the intricacies of Boyle's Law through an example involving isothermal compression of a perfect gas. Watch as we calculate the original pressure using the change in volume and final conditions. This tutorial simplifies complex gas laws for easy comprehension.
