Among the elementary subatomic particles of physics is the muon, which decays within a few nanoseconds after formation. The muon has a rest mass 206.8 times that of an electron. Calculate the de Broglie wavelength associated with a muon traveling at a velocity of 8.65×105 m/s .
A 26.0-g sample of ice at -11.0°C is mixed with 123.0 g of water at 90.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
The specific internal energy of helium at 300k and 1 atm pressure is 3800j/mol and the specific molar volumeat thesame temp. and pressure is 24.63l/mol.
The density of germanium is 5.325 g/cm^3 . If you made a 4 nm quantum dot of germanium, how many atoms would it contain? Assume the dot is spherical.
When you standardized the Sodium thiosulfate, what molarity of Na2S2O3 did you observe for each of your 3 trials.
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
How many grams of KOH are required to neutralized 300ml of 5.0 N HN03 solution.
Explain why the in phase vibration is located at a higher frequence than the out of phase stretch in the case of acetylene.
A 295mLflask contains pure helium at a pressure of 742torr . A second flask with a volume of 465mL contains pure argon at a pressure of 717torr .
A 2.0 L tank at 298 K contains oxygen gas with a partial pressure of 3.8 atm and helium gas with a partial pressure of 5.2 atm.
A mixture consists of 323 mg of methane, 165 mg of argon, and 223 mg of nitrogen. The partial pressure of nitrogen at 275 k is 19 kPa.
suppose the flame on a gas burner emits light just like a blackbody. The flame appears blue, emitting most of its light at a wavelength of 475 nanometers.
Acetylene gas (C2H2) used in welding, produces an extremely hot ?ame when it burns in pure oxygen according to the reaction 2 C2H2(g)+5 O2(g) -→ 4 CO2(g)+2 H2O(g)
