A student dissolves 12.8 g of ammonium nitrate (NH4NO₂) in 200. g of water in a well-insulated open cup. She then observes the temperature of the water fall from 22,0 °C to 16.5 °C over the course of 5.6 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NH NO3(s)→ NH(aq) + NO3(aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 2 significant digits. Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. 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 AH per mole of NH NO rxn exothermic…

I did a lab in which I dissolved sodium bicarbonate and sodium acetate in water, using a simple styrofoam cup as a calorimeter. For sodium bicarbonate, the temperature decreased from 20.8 degrees Celsius to 16.6 degrees Celsius. For sodium acetate, the temperature decreased from 18.4 degrees Celsius to 17.5 degrees Celsius. I used 150 mL of water to dissolve sodium bicarbonate, and 32.5 mL of water to dissolve sodium acetate. I used 15 grams of sodium bicarbonate and 3.25 grams of sodium acetate. I calculated that -2.64 kJ was released in the reaction for sodium bicarbonate, and -0.122 kJ was released in the reaction for sodium acetate. I also calculated that 0.18 moles of sodium bicarbonate were used and 0.0396 moles of sodium acetate was used. I then got -14.67 kJ/mol as the molar heat of solution for sodium bicarbonate, and -3.08 kJ/mol for the molar heat of solution for sodium acetate. However, when I calculate the percent errors, I am getting numbers of over 100. Did I do…
