The cell reaction is spontaneous with a standard cell potential of 5.85 V. B. The cell reaction is spontaneous with a standard cell potential of 0.11 V. C. The cell reaction is nonspontaneous with a standard cell potential of -0.11 V. D
A sample of nitrogen occupies a volume of 500 mL at 60 C and 500 mm Hg of pressure.What will its volume be at STP
The half-life of plutonium-239 is 24,100 years. How long will it take for a 100 g sample of plutonium to be reduced to 25 g?
a mixture is 10.0 mole ethyl alcohol 75.0 mole ethyl acetate c4h8o2 and 15.0mole acetic acid. calculate the mass
Determine the limiting reactant in each of the following reactions. Circle (Just label) the formula for the limiting reactant in each problem.
Which process would have a entropy greater than 0. a. n2(g)+3H2(g) = 2nh3(g) b. ch4(g) + h2o(g) = co(g) + 3h2(g) I believe it's b. because the molar masses of the products are similar so I would say that b. has more complex species so it's entropy..
A 65g sample of xenon at 298.15 K is allowed to expand adiabatically from an initial pressure of 3.0 bar to a final pressure of 0.5 bar. (Cp = 20.786 J/(K mol)), Cv can be found by assuming that xenon is ideal. If this expansion is reversible, wha..
