Two gases and are found in the atmosphere in only trace amounts because they decompose quickly. when exposed to ultraviolet light the half-life of is , while that of is . suppose an atmospheric scientist studying these decompositions fills a transparent flask with and and exposes the flask to uv light. initially, the partial pressure of is greater than the partial pressure of .

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
