CHEM 104: Chemistry

Discover the simple yet essential method for counting the number of oxygen atoms in different molecular sets, including molecules and ions.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

In biochemistry, polymers are essential macromolecules, including carbohydrates, lipids, proteins, and nucleic acids, each adopting specific shapes and performing vital functions within cells, with proteins serving diverse roles, nucleic acids carrying genetic information, catalysis expediting reactions, and the genetic code enabling protein synthesis.

Discover the step-by-step process of Barium Sulfate formation from the reaction of Barium Chloride with Sodium Sulfate. Learn about molar mass calculations stoichiometry and yield predictions.

Unravel the Lewis structures of BrF?, ClF?, and IF? and their relationship with the octet rule. Examine how fluorine bonds with bromine, chlorine, and iodine. Identify molecules that deviate from the standard octet distribution.

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.
