Chapter 15, Problem 52P

11A.4 Radiation of wavelength 268 nm passed through 1.5 mm of a solution that contained benzene in a transparent solvent at a concentration of 0.080 mol dm^−3. The intensity of the radiation is reduced to 22 per cent of its initial value (so T = 0.22). (a) Calculate the absorbance and the molar absorption coefficient of the benzene. (b) What would be the transmittance through a cell of thickness 3.0 mm?   Before solving the problem please also give a brief explanation of the concept or associated equation(s) and variables

11B.12 Suppose that hydrogen is replaced by deuterium in 1H35Cl. Would you expect the J = 1 ← 0 transition to move to higher or lower wavenumber?   Before solving the problem please also give a brief explanation of the concept or associated equation(s) and variables.

9B.3    Before solving the problem please also give a brief explanation of the concept or associated equation(s) and variables.

12.8 When 1.00 g of urea [CO(NH2)2] is dissolved in 200 g of solvent A, the A freezing point is lowered by 0.250°C. When 1.50 g of the nonelectrolyte Y is dissolved in 125 g of the same solvent A, the A freezing point is lowered by 0.200°C. (a) Find the molecular weight of Y. (b) The freezing point of A is 12°C, and its molecular weight is 200. Find Afus of A.

What you do in the lab step by step of identification of electrochemistry redox reaction (Oxidation Reduction)experiment.Include glassware used, chemicals used, amounts of chemicals used, concentrations of chemicals, etc

Please correct answer and don't used hand raiting

What do you think you will be doing in the electrochemistry redox reaction (Oxidation Reduction) experiment, and then answer- Will a species be reduced or gain electrons when a species is oxidized? Also, you should explain how you plan to use the different chemicals, glassware, tools, and equipment?

For the following products, propose two sets of reactants to obtain them. (The immediate precursors) OH OH
