CHEM 111: General Chemistry 1

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 fascinating process of calculating the mass of silicon in Earth's crust. Learn how to convert Earth's total mass to grams, determine the crust's mass percentage, and find the silicon's mass within the crust. Discover the scale of silicon's presence in our planet's outer layer.

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