The chemical reaction for a zinc-oxygen cell is:
Zn (c) + 1/2O2(g) + H2O (l) = Zn(OH)2 (c)
and the thermodynamic properties at 25 oC yield:
DHo = -357.42 kJ/mol; DGo = -317.94 kJ/mol
a) Calculate the reversible emf of the cell and its temperature coefficient;
b) Determine the amount of heat to be supplied or removed from the cell to maintain a constant temperature of 25 oC under reversible conditions;
c) Calculate the cooling rate necessary to maintain a constant temperature of 25 oC when the cell delivers a current of 1 ampere under 1 volt.
Cobalt was used as an internal standard to analyze a sample of titanium with atomic absorption spectroscopy. A mixture was prepared by combining a 4.00 mL Ti solution of unknown concentration with 3.00 mL of a 11.7 micrograms/mL solution of Co
What is the isentropic work required for the ideal gas case? C) If the comppressor has an efficiency of 0.78 and is NON-ideal, what is the final temp and required work?

You are given the following data. S(s) + 3/2 O2(g) → SO3(g) ΔH = -395.2 kJ 2 SO2(g) + O2(g) → 2 SO3(g) ΔH = -198.2 kJ Calculate ΔH
What is the molar concentration of free (uncomplexed) Ag+ in solution when 4.25g AgNO3 is dissolved in 100.0 mL 1.00 M NH3 aqueous
The ice was poured out into another container leaving a wet, empty beaker that weighed 46.146g. How much ice was poured into the other container?
An electron moves from n = 1 to the n = 6 energy state on absorbing energy. Match the energy absorbed (in Joules) with the one electron ion to which this electron belongs.

A helium-filled weather balloon has a volume of 714 L at 23 oC and 759 mmHg. It is released and rises to an altitude of 4.80 km, where the pressure is 495 mm Hg and the temperature is -9oC. what is the volume of the balloon at this altitude.
You created a buffer system by first neutralizing the supernatant solution containing Pb2+, Fe3+, Al3+, Ca2+, Cu2+, and K+ ions with 6M NH3 solution , and then adding an equal additional volume of 6M NH3 solution. Explain what forms of NH3 were pr..
Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating.
The following oxidation/reduction reaction of copper and tin has an equilibrium constant equal to 1.48 at 300 Kelvin. At this temperature the equilibrium concentrations are measured to be [Sn^2+]=0.124 M, [Cu+]=0.148 M and [Sn^4+]=0.176.
