Photochromic sunglasses, which darken when exposed to light, contain a small amount of colorless AgCl embedded in the glass. When irradiated with light, metallic silver atoms are produced and the glass darkens: AgCl→Ag+Cl. Escape of the chlorine atoms is prevented by the rigid structure of the glass, and the reaction therefore reverses as soon as the light is removed.If 310 kJ/mol of energy is required to make the reaction proceed, what wavelength of light is necessary?
Mark all the true statements A.) The value of [R]/[P] is the equilibrium constant B.) The amount of P present will not change. C.) The concentration of [R] is constant. D.) The reaction P--> R no longer takes place
Place palmitic acid at the middle position. Cis/trans isometry is graded -it may help to draw hydrogen atoms associated with the carbon atoms of the double bond.
In the following chemical equation, what is the reactant. CuSO4·5H2O(s) ® CuO(s) + SO3(g) + 5H2O(l)
the reaction produces 0.90 mol of CO2 and 0.45 mol of H2O. Determine the number of mols of carbon in the compound. Determine the number of mols of hydrogen in the compound.
An aqueous solution contains the amino acid glycine. Assuming that the acid does not ionize in water, calculate the molality of the solution if it freezes at -1.1 degree centigrade.
What is the pH of a buffer system that contains 0.240 M hydrocyanic acid HCN and 0.190 M sodium cyanide NaCN? The pKa of hydrocyanic acid is 9.31.
Draw (2R,3S)-2-bromo-3-phenylpentane in the conformation from which it is most likely to undergo E2 elimination to give 3-phenyl-2-pentene.
AgBr is the light-sensitive compound in most photographic films. Assume, when film is exposed, that the light energy absorbed dissociates the molecule into atoms.
Tungsten trioxide (WO3) has a rich yellow color and is often used as a pigment in ceramics and paints. In order to test a ceramic vase for its WO3 content, a 10.00 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO3 to W3 . ..
The normal range for the carbonyl group of a carboxylic acid in the IR spectrum is 1725 - 1700 cm-1. Why is the carbonyl group of benzoic acid appear at 1696 cm-1
cyclohexane-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the first 1 mL fraction look different from that of the last 1 mL fraction?
Exactly 100 mL of 0.10 M nitrous acid (HNO2) are titrated with a 0.10 M NaOH solution. Calculate the pH for the following. (a) the point at which 80 mL of the base has been added
