CHS 3501: Survey of Forensic Science

Explore the complex challenges scientists face when attempting to extract respiratory complexes from the inner mitochondrial membrane for an in-depth study of their properties and functions."

Understanding pH Values: In this video we break down the pH levels of various solutions. Discover the importance of acid strengths via Ka and pKa contrast weak vs. strong acids and learn the counterintuitive relationship between pOH and pH.

Learn the art of precise chemical calculations in this video. Discover how Chromium(III) oxide reacts with hydrogen sulfide to form chromium(III) sulfide and water, all while unraveling the necessary steps to determine the exact quantities involved.

In this analysis, we determine the composition of a solution prepared by dissolving 12.15g of nickel(II) nitrate in 175mL of water (density 1.00 g/mL). The mass percent of nickel(II) nitrate is found to be approximately 6.50%, and the mole fraction of nickel(II) ions in the solution is calculated as 0.00672.

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.

Discover Lewis structures for various molecular formulas, including N2, HCN, CO2, C3H6, and more. Explore their chemical bonding and structural arrangements.
