Direct ethanol fuel cells (DEFCs) have shown some promise as a viable option for providing "green" energy to small electrical devices. Calculate E° for the reaction that takes place in DEFCs: C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)
Use the following values.

∆G°H2O(l) = -237 kJ/mol
∆G°O2(g) = 0 kJ/mol
∆G°CO2(g) = -394 kJ/mol
∆G°C2H5OH(l) = -175 kJ/mol.
Eo = ? V

How many grams of ammonia would be produced by the decomposition of 16.93 mlof hydrazine? (the density of hydrazine is 1.021g/ml)

The term gas is limited to those substances that exist in the gaseous state at
