CHEM 116: Principles of Chemistry: Energetics and Dynamics

Explore the method to determine the equilibrium constant for a reaction between iron III ions and thiocyanate ions. Learn to deduce equilibrium concentrations from initial values and reaction stoichiometry. Grasp the importance of the equilibrium constant value of 325.1 in assessing the reaction's favorability.

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.

This video explores the processes of rusting in iron and burning a match, addressing whether the observed changes in mass violate the law of conservation of mass, and explains how these processes align with the law.

This video breaks down the process of calculating the time and number of photons required to boil water in a microwave. Using given power, wavelength, and water specifics, we determine both energy needs and photon count.
