CHEM 161: General Chemistry

Understand the fundamental distinctions between pure substances and mixtures. Unpack the definitions and real-world examples of elements, compounds, homogeneous, and heterogeneous mixtures.

This discussion highlights the significance of studying chiral molecules in biochemistry, emphasizing their impact on biological activity, molecular recognition, pharmacokinetics, and biomedical research, without revealing specific examples or findings.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

Exploring the titration of 25.00 mL of 0.08230 M KI with 0.05110 M AgNO3. This video breaks down the calculation process for the potential of silver ion at various volumes of added AgNO3: 39.00 mL equivalence point and 44.30 mL. With clear steps and using the solubility product constant understand how the potential of silver ion is determined for each scenario.

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.

Explore the chemical structures of four distinct ethers: ethyl propyl ether dibutyl ether methyl hexyl ether and dipentyl ether. Understand the role of ether groups which involve an oxygen atom connected to two alkyl or aryl groups.
