CHB 1101: Environmental Chemistry

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.

Learn how to compute the freezing point of water at various solution concentrations using the freezing point depression formula. Uncover the relationship between concentration and the lowered freezing points for four distinct solutions. Equip yourself with essential knowledge on the effects of solute concentration on water's freezing behavior.

Explore the classification of select molecules based on their polarity. Understand the electron distribution and molecular shapes of Formaldehyde, Methanol, Dichloromethane, and Carbon dioxide. Discover which ones exhibit a net dipole moment and which ones don't.

This discussion explores the nature of hydrogen peroxide as a compound composed of hydrogen and oxygen atoms and categorizes it as either a homoatomic or heteroatomic molecule.

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 protonation of amino acids, specifically valine and threonine, when subjected to a pH lower than their isoelectric points, highlighting the structural changes in their carboxyl and amino groups.
