CHEM 8901: Special Problems

Explore the concept of bond energy with the H-Cl bond as a prime example. Delve into the energy dynamics of bond breaking (endothermic positive ?H) versus bond formation (exothermic negative ?H). Understand how the magnitude remains consistent but signs differ based on energy absorption or release.

Discover the intricacies of the electron configuration for phosphorus, from its atomic number to its orbital notation. Learn about unpaired electrons, energy levels, and the significance of inner-shell electrons. Understand how orbital structures define an element's properties.

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

Explore the intriguing contrast between Pentanol and Hexane's viscosity at 20 degrees Celsius. Uncover how molecular interactions influence a liquid's 'thickness' and discover why similar molecular weights can lead to vastly different substance properties

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

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