2, 3-dimethylbutane from propane
Calculate DG0 for the reaction below. The standard molar entropy change for the reaction at 298 K is -287.5 J/mol·K.
HC9H7O4(aq) + H2O(l) image from custom entry toolH3O(aq) + C9H7O4(aq) Two aspirin tablets, each containing .325 g aspirin(along with a nonreactive "binder" to hold the tablet together), are dissolved in 200.0 mL of water. Calculate the pH of the ..
The hydrogen atom now has a single electron in the 3d subshell. Calculate the energy (in kJ/mol) required to ionize this (excited state) hydrogen atom. This is the energy required to remove the electron completely from the atom
A 25.00mL sample of KNO3 solution was diluted to 1.000 x 10^3 mL. The concentration of the final solution is 0.00383 M. Calculate the concentration of the original solution in M.
A thermometer containing 9.5 of mercury has broken. If mercury has a density of 13.6 , what volume spilled
Explain a pressurized tank of helium gas initially at 9bar and 36 C is cooled until the pressure reaches 5bar. Define what is the final temperature of the gas
In the chemical kinetics experiment, describe how you plan to mix the dye and bleach to start the reaction and when you expect to start recording the time? Include the volumes of dye and bleach solution you intend to mix? How are you going to make..
In running column chromatography under the following conditions, you get results that are less than ideal. Consider the situation in each case and suggest a correction.
a balloon is filled to a volume of 5.0 102 ml at a temperature of 29.0degc. the balloon is then cooled at constant
Draw the product of the reaction of cyclopentanone with chromic acid. If no reaction occurs, draw cyclopentanone. Hydride reduction (with LiAlH4 or NaBH4) of (S)-3-phenyl-2-butanone has been reported in the chemical literature and gives a mixture o..
