A sample of methane gas has a volume of 29mL at a pressure of 2atm. What is the volume of the gas (in mL) at 6.2 atm? Assume that there is no change in the temperature and the amount of the gas.
A certain rifle bullet has a mass of 9.81 g. Calculate the de Broglie wavelength of the bullet traveling at 1433 miles per hour.
What are the equilibrium partial pressures of \rm PCl_3 , \rm Cl_2, and \rm PCl_5, respectively. For the exothermic reaction PCl3(g)+Cl2(g)\rightleftharpoons PCl_5(g) K_{\rm p} = 0.100 at a certain temperature.
The subsequent charges on individual oil droplets were obtained during an experiment similar to Millikan's determine a charge for the electron in Coulombs
An emission line from K atoms is found to have two closely spaced components, one at 766.70 nm and the other at 770.11 nm. Account for this observation, and deduce what information you can.
Explain what is the value of the activity coefficient of Pb2 at 55.00°C while the ionic strength is 0.074 M. Crack using the temperature-dependent form of the extended Debye-Huckel equation.
The molar absorptivity for the complex formed between bismuth (III) and thiourea is 9.32 x 103 L mol-1 cm-1 at 470 nm. Calculate the range pf permissible concentrations for this complex if the percent transmittance is to be greater than 15.0 % and..
There is no net force acting on the puck. Assuming it doesn't smash into anything, how FAST will the puck be going 2 h later?
Is the gas produced in this experiment really an "ideal" gas? Explain. The production of gas in this experiment is fairly slow, but its production in a car airbag is quite rapid.
The equation for the velocity of a fluid stream measured with a Pitot tube is: v=sqrt[2delta(p)]/(d) where:v=velocity,
The pH at 25 °C of an aqueous solution of the sodium salt of p-cresol (NaC7H7O) is 11.60. Calculate the concentration of C7H7O- in this solution, in moles per liter. Ka for HC7H7O is equal to 6.7E-11.
A gas sample has an original volume of 680 ml when collected at 720 mm and 28°C. What will be the volume of the gas sample if the pressure increases to 820 mm and the temperature increases to 55°C
Compute the total change in Enthalpy (delta H) if you heat 25 grams of mercury liquid from 25 degrees Celsius to 75 degrees Celsius as well as also increase the pressure from 1 bar to 75 kbar
