Calculate E°cell and indicate whether the overall reaction shown is spontaneous or nonspontaneous. O2(g) + 4H+(aq) + 4e- Picture 2H2O(l); E° = 1.229 V Al3+(aq) + 3e- Picture Al(s); E° = -1.662 V Overall reaction: 4Al(s) + 3O2(g) + 12H+(aq) ? 4Al3+(aq) + 6H2O(l) Answers: E°cell = -2.891 V, nonspontaneous E°cell = -2.891 V, spontaneous E°cell = 2.891 V, nonspontaneous E°cell = 2.891 V, spontaneous Spontaneous, but none of these values of E°cell is correct.
calculate the value of Keq at 298 K for each of the following reactions
what products may have been formed during the combustion of the gas?
Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion.
Heat the solution to a gentle boil and maintain the heat for 1 minute to remove dissolved carbon dioxide. Add 4-8 drops of bromophenol blue indicator, which is yellow in acidic solution and blue in basic solution. If the solution is blue, pipet an..
