Differentiate between the spectral features in the MS, CNMR, HNMR and IR of benzoic acid and methyl benzoate
If the symbol X represents a central atom, Y represents outer atoms, and Z represents lone pairs on the central atom, the structure. Classify these structures by the hybridization of the central atom.
Calculate the standard free energy change for the process N2O5(s)-->N2O5(g) at 25 0C if Vapor pressure of N2O5 at 7.5 degrees C is 100mmHg, and the solid sublimes at a pressure of 1.00 atm at 32.4 0C.
The rate of the reaction will increase if the pressure of the gases increases. The rate of the reaction will remain constant with increasing temperature. The rate of the reaction will increase as time increases.
A 1.994 g sample of ethanol is combusted in a bomb calorimeter. The temperature of the calorimeter increases by 10.91 K. If the heat capacity of the bomb is 615.5 J/K and it contains 1.150 kg of water, what is the enthalpy change per mole of ethan..
Calculate the value of the equilibrium constant for the reaction that occurs when solid sodium oxalate is dissolved in water.
Phenol is a weak acid that is sometimes used as a disinfectant. Calculate the pH of a solution of 0.0100 M phenol. Ka for phenol is 1.3 X 10-10.
The blue color of the sky is due to the scattering of sunlight by the molecules in the air. The blue light has a frequency of about 7.5 x 10^14 Hz.
How many grams of oxygen are needed to react completely with 1290 grams of pentanone (C5H10O)?
7.80 g of CuNO3 is dissolved in water to make a 0.720 M solution. What is the volume of the solution? Answer should be in mL.
In a titration experiment, 50.0 mL of 0.375 M HI solution is required to neutralize 35.0 mL of Ca(OH)2 solution. What is the concentration of the Ca(OH)2 solution?
A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent.
If 95.0 mg of fluorine-18 is shipped at 8:00 a.m., how many milligrams of the radioisotope are still active if the sample arrives at the radiology laboratory at 1:30 p.m.
