This cell would aid in hemostasis.

Consider the reaction:  Fe2O3(s) + 3H2(g) —–> 2Fe(s) + 3H2O(g)  Use ΔG°f values in Appendix 4 to calculate ΔG° for this reaction.Is this reaction spontaneous under standard conditions at 298 K?  The value of ΔH° for this reaction is 100. kJ. At what temperatures is this reaction spontaneous at standard conditions? Assume that ΔH° and ΔS° do not depend on temperature.  

The enthalpy of vaporization of ethanol is 38.7 kJ/mol at its boiling point (78 °C). Determine ΔS sys, ΔS surr, and ΔS univ when 1.00 mole of ethanol is vaporized at 78°C and 1.00 atm.

As a system decreases in volume, it releases 50.0 J of energy in the form of heat to the surroundings. The piston has an internal pressure of 0.500 atm. The final volume of the system is 42.0 L. What was the initial volume of the system if the internal energy of the system increased by 115.0 J?

Which is a physiological symptom of test anxiety mentioned?
