A particular sensitizer can absorb photons of one wavelength and release photons of a longer wavelength. Why must the radiation be at a longer wavelength
What is the pH of the solution at the cathode if E^o cell = -0.362V for the following electrochemical cell at 25 degrees C? Pt | Hw(g,1.0 atm) | H+(aq, 1.00M) || H+(aq) | H2(g,1.0atm) | Pt
Glycerol, C3H8O3, is a water-soluble liquid of density 1.2656 g/ml at 15oC. Calculate the molarity of a solution of glycerol made by dissolving 40.000 ml glycerol at 15oC in enough water to make 250.000 ml of solution.
Isobutane is the fuel used in disposable lighters. The lighters' operation is dependent upon the butane's ability to vaporize and be ignited, and this depends somewhat upon the large pressure difference between the inside of the lighter and the at..
What mass of sodium chloride would need to be added to the blood to bring the sodium ion concentration up to 0.140 M , assuming no change in blood volume
What volume of a 0.1 M ClO- solution reacts stoichiometrically with a 10 mL solution of 0.2 M CrO2-? Use the reaction 2 CrO2- + 3 ClO- --> 2 CrO4-2 + 3 Cl- to assist in the calculation. You do not have to balance the oxygens and hydrogens in the r..
