A student measured the molar heat of neutralization of a monoprotic acid with NaOH and the following data was obtained. Calculate the AHrx per mole of acid. Ti = 24.3°C V(acid) = 50.0 mL V(base) = 50.0 mL T(final) = 32.2°C [acid] = 1.02 M [NaOH] = 1.05 M C(cal) = 8.5 J/°C
2.948 g of NH4Cl (53.19 g/mol) are added to 50.0 mL of water (18.02 g/mol, density = 1.00 g/mL) and the temperature changes from 22.30oC to 18.90oC. Use this information to calculate the enthalpy change (kJ/mol) for the reaction illustrated in equation 6 of the laboratory procedure. Use 4.18 J/(goC) as the specific heat of the solution.
A solution of 75.0 mL of 3.20 M HNO3 was mixed with 50.0 mL of 2.00 M Ca(OH)2 in a large Styrofoam coffee cup; the cup is fitted with a lid through which a calibrated thermometer passes. The temperature of both solutions before mixing was 20.1 °C. After the Ca(OH)2 solution is added to the coffee cup and the mixed solutions are stirred with the thermometer, the maximum temperature measured was 39.2 °C. Assume that the volumes are additive but that the density of the mixed solution is 1.10 g/mL, the specific heat of the mixed solution is 4.18 J/g•°C, and no heat is lost to the surroundings. In much the same way as you did for the previous question, calculate the enthalpy change per mole of HNO3 in the reaction. Consider that only reactants that actually react will account for the heat produced.

2.887 g of NH4Cl (53.19 g/mol) are added to 50.0 mL of water (18.02 g/mol, density = 1.00 g/mL) and the temperature changes from 22.30oC to 18.90oC.

(6) NH4Cl(s) → NH4Cl(aq) ∆H6 (measured) Your answer should have 3 sig figs
A student dissolves 10.3g of ammonium nitrate NH4NO3 in 300.g of water in a well-insulated open cup. He then observes the temperature of the water fall from 22.0°C to 19.3°C over the course of 3.1 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH4NO3s -> NH+4aq + NO−3aq You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to the correct number of significant digits. Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case. Calculate the reaction enthalpy ΔHrxn per mole of NH4NO3.
