Calculate the standard emf of a cell that uses Mg/Mg2+ and Cu/Cu2+ half-cell reactions at 25°C.
A gas cylinder that contains argon has an internal volume of 6.88 L. A pressure gauge attached to the cylinder reads 1870 psi (1 atm = 14.7psi) at 20.0C.
You have a system with a movable piston that is isolated. The reaction inside the system is under adiabatic conditions. When the reaction (the burning of butane in oxygen) is started, the distance the piston traverses is 30.00 cm at 1.000 atm of p..
