CHEM 3653: Introduction to Biochemistry

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.

Explore oxidation and reduction processes across four chemical reactions differentiating between acid-base and redox activities. Highlighting key substances and their roles in each reaction.

Learn how to calculate the molarity of different solutions containing methanol, calcium chloride, and naphthalene. Essential for chemistry enthusiasts.

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

Explore the distinct chemical formulas of various acids like phosphoric, hydrobromic, and sulfurous acids. Understand their practical applications, from flavoring agents to sanitization in brewing. Highlighting their unique molecular makeup, learn the critical roles they play.
