Ethyl alcohol is soluble in water because of the OH group. Can you use extraction to separate benzoic acid from ethyl alcohol it is dissolved in?
identify the following compound from its IR and proton NMR spectra. C5H6O: IR: 3300 (sharp), 2102, 1634 cm-1 NMR: ? 3.10 (1H, d, J = 1 Hz); ? 3.79 (3H, s); ? 4.52 (1H, doublet of doublets, J = 10 Hz and 1 Hz); ? 6.38 (1H, d, J = 10 Hz)
At 25 °C, the equilibrium partial pressures for the following reaction were found to be PA = 1.40 atm, PB = 8.90 atm, PC = 5.10 atm, and PD = 2.50 atm.
One mole of H2O(g) at 1.00 atm and 100.°C occupies a volume of 30.6 L. When one mole of H2O(g) is condensed to one mole of H2O(l) at 1.00 atm and 100.°C, 40.66 kJ of heat is released. If the density of H2O(l) at this temperature and pressure is 0.996..
