CHE 320: Database Management Systems

Explore the differences between physical and chemical properties in substances. Learn some fundamentals of chemistry and understand how substances interact and change.

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.

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

Unravel the chemistry behind precipitation reactions and the creation of insoluble salts. Learn how aqueous ions interact to form solid precipitates, illustrated with examples like silver nitrate and sodium chloride. Understand their significance in fields from water treatment to qualitative analysis.

Compare the acidity of chromium trioxide (CrO?) and chromium (II) oxide (CrO) in water. Chromium trioxide forms strong chromic acid increasing hydronium ions, while chromium (II) oxide has weaker oxidizing properties, resulting in a less acidic solution.

Unravel electron configurations for transition metals including zinc copper zirconium and iron. Understand how atomic number influences electron arrangement based on the Pauli exclusion principle Hund's rule and the Aufbau principle. Decode the configurations of each metal with clarity.
