Fuel cells use nitrogen to dilute a mixture of hydrogen with water and oxygen, which is formed from the decomposition of water, which is used to generate electricity and heat. What is the enthalpy of mixing (ΔHmixed, in kJ) that results from diluting an ideal mixture of 0.5 mol of hydrogen, 0.1 mol of oxygen and 3 mol of water with 8 mol of nitrogen to feed a fuel cell? Also, find ΔS mixed. Temperature is 850K.

Make an estimate of the composition of carbon, hydrogen, oxygen, and nitrogen in the dry mass of a bacterium. Using knowledge of the size and mass of a bacterium, the fraction of that mass that is "dry mass" (that is, ca. 30%) and the chemical constituents of a cell, figure out the approximate small integers (< 10) for the composition CmHnOpNq, that is, find m, n, p, and q.

A) The reaction between hydrogen and oxygen to form water is highly exothermic. Which statement is true of the energies of the bonds that break and form during the reaction? The energy needed to break the required bonds is about the same as the energy released when the new bonds form. The energy needed to break the required bonds is less than the energy released when the new bonds form. The energy needed to break the required bonds is greater...

A direct hydrogen fuel cell uses hydrogen and air (oxygen) to produce electricity, as we showed in class. If you wanted a voltage of 2.2 V for your fuel cell device (which can be made of multiple cells), what mix of conversion and/or number of cells would you want to use? Remember: the voltage of cells in series adds up. There are a variety of possible answers.
