Consider the reaction. \(\mathrm{Fe}^{3+}(a q)+\mathrm{SCN}^{-}(a q) \rightleftharpoons \mathrm{FeSCN}^{2+}(a q)\) A solution is made containing initial \([\mathrm{Fe} 3+]=1.0^{*} 10-3 \mathrm{M}\) and initial \([\mathrm{SCN}-]=8.0 * 10-4 \mathrm{M} .\) At equilibrium, \([\mathrm{FeSCN} 2+]=1.7^{

An Introduction to Thermal Physics 1
Problem 66P In analogy with the thermal conductivity, derive an approximate formula for the viscosity of an ideal gas in terms of its density, mean free path, and average thermal speed. Show explicitly that the viscosity Is Independent of pressure and proportional to the square root of the temperatur

The thin outer layer of Earth, called the crust, contains only 0.50 percent of Earth's total mass and yet is the source of almost all the elements (the atmosphere provides elements such as oxygen, nitrogen, and a few other gases). Silicon (Si) is the second most abundant element in Earth's crust (27.

Cereal A companys cereal boxes advertise 9.65 ounces of cereal. In fact, the amount of cereal in a randomly selected box follows a Normal distribution with mean m = 9.70 ounces and standard deviation s = 0.03 ounces. (a) What is the probability that a randomly selected box of the cereal contains less
