If instead of a vapor we start with an equimolar liquid mixture of the same components at 120ºC and high pressure and the pressure is lowered, what is the bubble point (pressure at which the first bubble forms)?. What are the compositions of the liquid and vapor phases at the bubble point?. At what pressure the last drop of liquid evaporates if at constant temperature we keep reducing the pressure?

In 1995 a research group led by eric cornell and carl wiemann at the university of colorado successfully cooled rubidium atoms to the 20-200 nk temperature range. assuming (incorrectly) that the rubidium atoms behave liké particles of a classical ideal gas, calculate the rms speed of a rubidium atom at a temperature of 112.0 nk. in the experiments one particular isotope of rubidium was used, rubidium-87. the molar mass of this isotope is 86.91 q/mol. tries 0/20 submit answer

How have the competing explanations' experiments on atoms affected the development of the atomic model?

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve
