CHEM 4: Biochemistry II

Discover how to craft balanced, complete ionic, and net ionic equations for various chemical reactions. Learn the significance of aqueous ions and solid state indicators in these equations.

Delve into the journey of scientific ideas as we discuss how a hypothesis can evolve into a theory, and whether a theory can ever become a law. Uncover the distinctions and connections between these fundamental elements of scientific understanding in this illuminating video.

Determine the molarity of a NaOH solution through titration with sulfurous acid. Starting with the ideal gas equation we derive the concentration of a 0.200L SO?-derived H?SO? solution. Concluding with a molarity of 1.64 M for NaOH using calculated values.

Join us as we delve into the intriguing world of genetic coding and discover how the concept of wobble accounts for variations in codons encoding a single amino acid.

Learn the method to determine the count of SO? molecules, sulfur, and oxygen atoms from a given amount of sulfur dioxide (SO?). Understand the application of Avogadro's number in translating moles to molecules. Grasp key concepts of atomic structure and counting with hands-on examples.

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.
