A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HCl in a coffee cup calorimeter. If both solutions were initially at 35.0°C and the temperature of the resulting solution was recorded as 37.0°C, determine the experimental AHxt (in units of kJ/mol NaOH) for the neutralization reaction between aqueous NaOH and HCI. Assume that no heat is lost to the calorimeter or the surroundings, and that the density of the solution is...

Part 2, find AH°rxn =kJ/mol Two solutions are mixed in a coffee cup calorimeter both are initially at 22.60°C. When a 100.0 mL volume of 1.00 M AgNO3 solution is mixed with a 100.0 mL sample of 0.500 M NaCl solution, the temperature in the calorimeter rises to 28.30°C (assume no heat is lost to the surroundings and the density and heat capacity of the solutions is the same as that of water). Determine the AHºrxn for the reaction as...
