Consider the data table below to calculate the enthalpy of reaction for the neutralization of nitric acid by barium hydroxide.   Volume   of 1.021MHNO3,  mL 50.00 60.00 70.00 80.00 90.00 100.0 Volume of 0.572MSr(OH)2, mL 100.0 90.00 80.00 70.00 60.00 50.00 Change of temperature, oC 4.54 5.45 6.36 7.27 6.54 5.46 Analyze the Data Table to find the highest temperature and answer the following questions. Consider the density of the solutions to be the same as water, 1.00 g/mL, both before and after mixing, and the heat capacity is the same as for water, 4.18J/oCg.  Since your calculators may give you slightly different numbers, pick the closest answer. The highest temperature change in oC  Number of moles of acid  at the highest temperature (at stoichiometric ratio) Number of moles of the base  at the highest temperature (at stoichiometric ratio) Mole fraction of acid and mole fraction of base at the highest temperature (at stoichiometric ratio) Stoichiometric mole ratio for the reaction: moles acid/moles base, calculated Stoichiometric mole ratio for the reaction: moles acid/moles base, rounded to the whole number Heat absorbed by the solution in the calorimeter, J Heat in kJ produced by the reaction between solutions of acid and base in the calorimeter Heat of reaction in kJ per number of moles of base Thermochemical equation and Enthalpy of the neutralization reaction (Hint: Enthalpy is per number of moles of water) To receive full credit (10 pts for answers and 10 pts for showing work), submit a picture of your work to the Final Exam Required Work & Partial Credit  assignment AFTER SUBMITTING COMPLETED FINAL
