CHM 101: Armchair Chemistry

This video focuses on unit conversions and the practical use of conversion factors to translate quantities between different units. It provides clear examples of converting 70 kilograms to pounds, translating 14 billion years into seconds, changing the height of a basketball player from feet and inches to meters, and converting cubic meters to liters, illustrating the importance of this skill in various scientific and everyday scenarios.

Explore the fascinating world of intermolecular forces in this brief video, featuring HCl, F?, and C?H?? molecules. Learn about the bonds that hold these substances together!

Unravel the electron configurations of diverse ions and discern their noble gas resemblances. Understand how atoms and ions strive for full outer electron shells for ultimate stability.

The kinetic molecular theory of gases describes the random motion and speed distribution of gas molecules in a container, and when considering various statements about the average speeds of these molecules, it's important to understand how they behave under different conditions.

When an ionic compound dissolves in water, it undergoes dissociation into its constituent ions. The total moles of ions released is determined by adding up the moles of each ion generated during this dissociation process. In the case of (a) disodium hydrogen phosphate (Na?HPO?), it dissociates into two sodium ions and one hydrogen phosphate ion. For (b) copper(II) sulfate pentahydrate (CuSO? · 5H?O), it dissociates into one copper ion and one sulfate ion. In (c), nickel(II) chloride (NiCl?) diss

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.
