The antisymmetric -CH2-CO-O- stretching vibration in carboxylic acids is heavily mixed with the in-plane bending mode of the O-H group. In alcohols these two vibrations seldom show evidence of mechanical coupling. Explain.
The hydroxylamine I can be oxidized by MnO2 to the amide oxohaemanthidine (II). In dilute solution the carbonyl absorption band of II occurs at 1702/cm. Explain this observation.
Find either the wood oak or pine if The given density of oak = 0.9 g/cm 3 , the density of pine = 0.4g/cm 3 .
The partial pressure and Henry's law constants for SO2 and H2O2 are 2.7 ppm (KH = 1.2 mol L-1atm-1) and 4.9 ppb (KH = 1.0E5 mol L-1atm-1), respectively. Calculate the reaction rate of this process.
Assume that algae need carbon, nitrogen and phosphorus in the atomic ratio 106:16:1. What is the limiting nutrient in the lake that contains the following concentrations: total carbon = 20 mg/L, total N = 0.80 mg/L and total P = 0.16 mg/L.
