3. complete the following for liquid water at t = 373.15 k: a. plot f l versus p, using the peng robinson equation of state to calculate all values of f l . b. plot f l versus p, using the poynting method to calculate all values of fl . explain and justify your approach for determining fsat for thiscalculation. c. re-do parts a and b for liquid water at t = 473.15 k. discuss any differences in your approach for the two temperatures.

Bohr's model could only explain the spectra of which type of atoms? single atoms with one electron single atoms with more than one electron bonded atoms with one electron bonded atoms with more than one electron

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Which common material is an example of a polymer? (25 pts) a. steel b. plastic c. petroleum d. rubbing alcohol
