Find delta Go for the following equation: 2H2S(g) + 3O2(g) <--> 2H2O(g) + 2SO2(g) using delta Ho and So values at 298 K

3. One mole of liquid water at 100 °C is heated until the liquid is converted entirely to vapor at 100 °C and 1 atm pressure. Calculate q, w, AE and AH for each of the following. (a) The vaporization is carried out in a cylinder where the external pressure on the piston is maintained at 1 atm throughout. (b) The cylinder is first expanded against vacuum (Pext = 0) to the same volume as in part (a), and then sufficient heat is added to vaporize the liquid completely to 1 atm pressure.

Aqueous hydrochloric acid reacts with solid calcium metal to form a solution of calcium chloride and hydrogen gas. The reaction is highly spontaneous and proceeds to completion. A chemist reacts 65.30 g calcium with excess hydrochloric acid at STP. You may assume the gas behaves ideally under all conditions. (a) What volume of hydrogen gas is produced over water? (b) What is the final concentration (in mol/L) of calcium chloride in the solution if the initial acid solution had a volume of 0.85 L? Assume no change in solution volume. (c) All of the hydrogen gas that evolved during the reaction is collected and held in a rigid flask with a volume of 11.40 L. If the pressure in the flask cannot exceed 3.60 atm, what is the maximum temperature at which the gas can be stored in the flask?
