The following equilibrium reaction has a Keq value of 8.9x10^-7 2SO3 ? 2SO2(g) + O2(g) Calculate the equilibrium concentrations of all gases if 1.50 mol of SO3(g) is initially placed in a 3.00L reaction container?
Explain while X rays of wavelength 0.093 nm are diffracted by a metallic crystal, the angle of first-order diffraction (n = 1) is measured to be 15.2°. Explain what is the distance between the layers of atoms responsible for the diffraction
A sample of 0.0020 mole of HCL is dissolved in water to make a2000-mL solution. Compute the molarity of the HCL solution, the [H3O+], and the PH. For a strong acid such as HCL, the [H3O+] is the same as the molarity of the HCL solutions.
Diethyl ether is a volatile organic compound. The vapor pressure of diethyl ether is 401 mm Hg at 18°C and the Hvap = 26.0 kJ/mol. Calculate the vapor pressure of diethyl ether at 40°C.
Explain the intensity of a line for atomic Cs is much lower in a neutral gas flame, which operates at 1800°C than in a hydrogen-oxygen flame, whose temperature is 2700°C.
Treatment of the following stereoisomer of 1-bromo-1,2-diphenylpropane with sodium ethoxide in ethanol gives a single stereoisomer of 1,2-diphenylpropene. Draw the E2 elimination product of the reaction.
