Aniline (C6H5NH2, Kb = 4.3 x 10^-10) is a weak base used in the manufacture of dyes. Calculate the value of Kn for neautralization of aniline by vitamin C (ascorbic acid, C6H8O6, Ka = 8.0 x 10^-5). Does much aniline remain at equilibrium?
Benzene (C6H6) burns in air to produce carbon dioxide and liquid water. Calculate the heat released (in kilojoules) per gram of the compound reacted with oxygen. The standard enthalpy of formation of benzene is 49.04 kJ/mol.
Two moles of neon gas initially at 33.2C and a pressure of 0.6 atm are compressed adiabatically to one-third of their initial volume. Determine the pressure following compression. AND Determine the new temperature.
How much specific heat must be added or removed(isobarically) to maintain the cabin at 25 degrees Celsius? Consider the air as dry air.
A sample conaining both HCl and HNO3 had a density of 1.083g/ml. A 30.00 ml amount of this sample required 25.78 ml of 0.3248 M NaOH for titration. Another 30.00 ml amount of this sample required 24.47 ml of 0.1327 M AgNO3 for titration.
An ideal gas at temperature T0 is slowly com- pressed at constant pressure of 2 atm from a volume of 10 liters to a volume of 2 liters. Then the volume of the gas is held constant while heat is added, raising the gas tempera- ture back to T0. Calc
