Mercury has a boiling point of 357 degrees and the molar enthalpy of vaporization of 59.0 KJ per mole. What is the vapor pressure of mercury at room temperature, 25 degrees celsius.
Calculate the number of [CH2CHOH] monomer units in the average strand of PVA (78,000 g/mol).
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Perutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin
The air in an inflated balloon (defined as the system) warms over a toaster and absorbs 121 J of heat. As it expands, it does 70. kJ of work. What is the change in internal energy for the system.
Describe the intermolecular force that must be overcome in converting each of the following from a liquid to a gas
