CHEM 111: General Chemistry 1

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.

Explore the chemical combination of nitrogen and fluorine to produce nitrogen trifluoride. Learn how to determine the limiting reactant and calculate the theoretical yield using stoichiometry principles.

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.

Explore how to calculate the theoretical yield of TiCl? in moles based on different initial quantities of reactants in the chemical equation Ti + 2 Cl? ? TiCl?.

This video discusses the fundamental concept of DNA structure, focusing on the identification of the 3' and 5' ends of a DNA segment, specifically highlighting the sequence AGTCAT and its importance in understanding DNA strand direction for processes like replication and transcription.

Learn a practical application of chemistry and mathematics in your daily life. Whether you're a tea or coffee enthusiast, this video offers valuable insights into scale removal and maintaining your kitchen appliances.
