For each of the following equilibria, use Le Chatelier's principle to predict the direction of reaction when the volume is increased. [Part A] C (s) + H2O (g) --><-- CO (g) + H2 (g). [Part B] 2H2 (g) + O2 (g) --><-- 2H2O (g). [Part C] 2Fe (s) + 3H2O (g) --><-- Fe2O3 (s) + 3H2 (g). ((the possible answer choices for each part are: The reaction will go the products, reactants, or will remain at equilibrium))
Consider the cell described below: Al/Al3+ (1.00M)//Pb2+ (1.00M)/Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by .60 mol/L. Assume T=25 C
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Perutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin
