What spectral features in the MS, CNMR, HNMR and IR of benzoic acid and methyl benzoate allow you to differentiate between them
How do old dispersive infrared (IR) instruments use a grating to separate the infrared source by wavelength before passing through the sample?
Next, 1.50 g of this sodium salt was dissolved in water and diluted to 50.0 mL. Identify the dissolved substance: Is it an acid, a base, or is it amphiprotic. Calculate the pH of the solution.
The reaction of nitrogen dioxide with carbon monoxide NO2 + CO NO + CO2 is second order in NO2 and zero order in CO. Complete the rate law for this reaction in the box below
A 16 ounce specialty coffee drink contains 216 mg caffeine. If all the caffeine is extracted and dissolved in an equal amount of water, what is the pH of the solution. What is the percent ionization.
A mixture of a, b, and c gives three peaks in the GC with relative areas of 1:5.5:7.8, What is the percent composition of the mixture. (a walktrhough would be helpful)
The total pressure of a mixture of N2O4 and NO2 is 1.5 atm. If Kp=7.1 (at 25 degrees C) calculate the partial pressure of each gas in the mixture.
E1 mechanisms a little clearer? maybe make a chart with simmilarities and differences and how to know which one is which?
What is the pH of a solution that is 0.30 M in aniline, C6H5NH2, and 0.15 M in anilinium chloride, C6H5NH3+Cl-? (Kb = 4.2 × 10-10 for aniline) Aniline ionizes as: C6H5NH2 + H2O C6H5NH3+ + OH-
