Consider 1.00 L of air in a patient's lungs at 37.0 C and 1.00 atm pressure. What volume would this air occupy if it were at 25.0°C under a pressure of 5.00 102 atm (a typical pressure in a compressed air cylinder)?
What is the hydroxide-ion concentration of a 0.190 M oxalic acid, H2C2O4, solution? For oxalic acid, Ka1 = 5.6x10-2 and Ka2 = 5.1x10-5.
Determine the molecular weight of a compound given the gas phase data: mass of 11.8 g, temperature of 39.1 C, pressure of 630 torr, volume of 1.31 L.
For a gas sample of N molecules that consists of N1 molecules of mass m1 and N2 molecules of mass m2, follow through a derivation which led to the result PV=1/3mv2 and PV = nRT.
Consider a light-sensative reaction. What energy in joules per photon, is needed to drive the reaction if delta H of the reaction is equal to 793 kJ/mol. (Remember that there are Avogadro's number of photons per mole of photons.)
Nitrogen dioxide is obtained in a cylinder, but exists in equilibrium with dinitrogen tetrooxide. A 5.00g sample of this mixture is transferred to a 0.5L flask at 298K.
An excess of aluminum foil is allowed to react with 225 mL of an aqueous solution of HCl (d = 1.088 g/mL) that contains 18.0% HCl by mass.
A jogger runs at an average speed of 5.9 mi/h. a. How fast is she running in m/s? b. How many kilometers does she run in 98 min?
sample of ideal gas be compressed at constant temperature for delta s system to be -3.4j/k
A beaker with 170 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.70 mL of a 0.370 M HCl solution to the beaker. How much will the p..
