An equimolar mixture of H2 and D2 effuses through an orifice (small hole) at a certain temperature,
Calculate the composition (in mole fractions) of the
gases that pass through the orifice. The molar mass
of D, is 2.014 g/mol. Answers are .586 and .414 but I need help getting there.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
