CHEM 112: Chemistry in Society

This video breaks down the process of calculating the time and number of photons required to boil water in a microwave. Using given power, wavelength, and water specifics, we determine both energy needs and photon count.

Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.

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.

Uncover the distinct behaviors of hydrochloric acid and acetic acid in water. Learn about the complete ionization of strong acids and the partial ionization of weak ones, emphasizing the differentiation in proton donation.

In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts

Discover the process to determine the quantity of ammonia (NH?) required to produce a specific amount of ammonium sulfate ((NH?)?SO?). Through a step-by-step explanation, learn the application of the balanced chemical equation and molar mass conversions. Transform theoretical chemistry into practical knowledge with this insightful guide.
