if the partial pressures are oxygen 420 torr and helium 85 torr what is the partial pressure (torr) of the nitrogen in the mixture
13.2 grams of NaC2H3O2 are added to 1.00 L of a .100 M solution of acetic acid to form an acid buffer. Ka for acetic acid is 1.8e-5. What is the pH of the solution?
A perfect gas has a value of R= 58.8 ft-lb/lb-R and k= 1.26. IF 20 Btu are added to 5 lb of this gas at constant volume when the initial temperature is 90°F, what is the change in entropy?
A heat engine absorb 750J of heat from a hot performs 265J of work calculate the efficiency of the heat engine.
A chunk of plastic is weighed on a scale and has a mass of 68.29 g. Next, the chunk is submerged in a graduated cylinder with an initial volume of water of 100.0 mL. After the plastic is added, the new volume in the cylinder is 129.5 mL. Find the density of the plastic in g/cm3.
The fresh feed to ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole
% inerts. The mole ratio of H2:N2 is 3:1. The product stream consists of pure
ammonia. The conversion in the reactor is 15 %, a recycle stream is used and in order
to avoid build-up of inerts, a purge is withdrawn. The rate of purge stream is adjusted
to keep inert concentration in the recycle stream at 8 mole per cent. Calculate the
moles of ammonia produced.
