Calculate the maximum non-expansion work per mole that may be obtained from a fuel cell in which the chemical reaction is the combustion of propane at 298K
The Haber-Bosch process is a very important industrial process. In the Haber-Bosch process, hydrogen gas reacts with nitrogen gas to produce ammonia according to the equation 3H2+N2=2NH3
When N2O5 (g) is heated it dissociates into N2O3 (g) and O2(g) according to the following reaction: N2O5(g) N2O3(g) + O2(g) Kc= 7.75 at a given temperature. The N2O3(g) dissociates to give N2O(g) and O2(g) according the following reaction:
We have a fusion of metals A and B, their molar ratio is 1:1. If we pour 1.02 grams of this fusion into excess HCl solution, we will get 1120 mL of hydrogen gas. We would get the same amount of hydrogen gas if we poured 1.7 grams of our fusion int..
