CHEM 104: General Chemistry I - CHEM 121

Explore the intricacies of muscle contraction and the pivotal role played by elements like Calcium, Sodium, Potassium, and Chloride. Learn how Calcium directly triggers contraction by interacting with troponin and actin filaments. A thorough breakdown of each element's unique contribution to our body's movement.

We explore how to determine the nature of a mysterious, gelatinous substance found on a forest rock. By conducting a series of tests, including microscopy, DNA staining, respiration observation, and growth experiments, we aim to unravel whether this enigmatic material is alive, inanimate, or a product of a living organism.

Explore the fundamental characteristics of anions and decipher the statements that define them. Understand how electron transfer leads to ion formation, creating atoms with net electrical charges. Learn about the key property that sets anions apart from other atomic entities, providing insights into atomic structure and charge.

Gain a clear understanding of chemical equilibrium, where reactant and product concentrations stay constant due to equal forward and reverse reaction rates. Dispel common misconceptions about equilibrium, such as concentration equality and reaction reversibility.
