CHEM 123: Surgery General Organic Chemistry

Explore the power of chemical names and symbols in deciphering copper compound formation at each step of the copper cycle, with an illustrative example.

Converting Denver's average pressure of 24.9 in. Hg into various units. This video provides clear steps to determine equivalents in millimeters of mercury atmospheres pounds per square inch and pascals. Understand the relationships and conversions between these common pressure units.

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

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.

This video discusses the process of writing chemical formulas for different compounds, providing details on the types and charges of ions involved in each compound's composition. The video concludes with the chemical formulas for barium hydroxide, magnesium sulfite, calcium carbonate, ammonium sulfate, and lithium hydrogen carbonate.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.
