CHEM 3304: Fundamentals to Biochemistry

Discover the difference between strong and weak electrolytes by understanding their ionization in water. Using nitrous acid and nitric acid as examples, this video provides chemical equations that visually distinguish the ionization behavior of these electrolytes.

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.

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.

Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures

Discover the process of determining the final temperature of an iron nail after heat absorption. Using the specific heat capacity of iron and the heat transfer formula, we calculate the temperature increase and reveal the nail's new thermal state. This tutorial offers a clear understanding of how materials respond to heat.

Discover how to calculate the number of moles of hydrogen in different chemical samples, including H?O, NH?, N?H?, and C??H??.
