Carbon monoxide, CO, reacts with chlorine, Cl₂, to form the very poisonous gas phosgene, COC1₂. Calculate AHin using values from the table of thermodynamic properties. AHixn= Calculate AC, of the reaction from the given gaseous heat capacity data. J mol. K Cp (CO) = 29.9. J mol. K Cp (Cl₂)= 33.9. Cp (COC1,) = = 59.7 J mol. K J/mol

In a reaction, 1.00 mole of H2 is produced at a constant pressure of 1.00 atm and at 298 K (1 L atm = 101.3 J): 2 H2O(g) → 2 H2(g) + O2(g)     ΔH° = +483.6 kJ mol–1 How much heat is exchanged in this reaction?   +483.6 kJ   +967.2 kJ   +241.8 kJ

33.6 g of a salt solution was mixed with 27.5 g of water in a calorimeter with a calorimeter constant of 66.5 J K-1 with all substances initially at 30.9 °C. The resulting solution was observed to be at a temperature of 12.2 °C and have a heat capacity of 3.97 J g K-1. Determine q for the mixing process.

The thermite reaction, used for welding iron, is the reaction of FegO4 with Al. 8 Al (s) + 3 Fe3O4 (s) > 4 Al203 (s) + 9 Fe (s) AH° = -3350 kJ Because this large amount of heat cannot be rapidly dissipated to the surroundings, the reacting mass may reach temperatures near 3000°C. How much heat (in kJ) is released by the reaction of 16.5 g of Al with 76.7 g of Fe304? Enter your numerical answer in units of kJ.
