CHEM 1145: Principles of Chemistry I

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.

Understanding pH Values: In this video we break down the pH levels of various solutions. Discover the importance of acid strengths via Ka and pKa contrast weak vs. strong acids and learn the counterintuitive relationship between pOH and pH.

Learn how the ideal gas equation is derived from Boyle's law, Charles’ law, and Avogadro's principle, unraveling the fundamentals of gas behavior.

Discover the contrasting processes of vaporization and condensation and their thermal nature. Understand why boiling is endothermic, absorbing heat, while condensation is exothermic, releasing heat, and how these processes impact ?H values.

Understand gas stoichiometry by exploring the Ideal Gas Law, which integrates key laws like Gay-Lussac's, Charles's, Avogadro's, and Boyle's. Discover how this equation helps determine relationships between gas volumes and moles in reactions.
