How much energy is required to raise the temperature of 11.1 grams of solid iodine from 24.8 °C to 35.4 °C ? Answer: Joules.

During lab you are given two solutions to use for a coffee-cup calorimetry experiment. The instructor directs you to obtain one hundred milliliters of each solution to use in your experiment. The two solutions are 0.300 M AgNO3 and 0.300 M HCl. Combine the two solutions in a coffee-cup calorimeter and measure the temperature change. You determine the initial temperature is 21.80 �C and the final temperature is 23.20 �C. Assuming the density and specific heat of the resulting solution is 1.00 g/mL and 4.18 J/g ? �C, respectfully, what is the ?H�rxn?   Question 20 options:   +39.0 kJ/mol   +1.17 kJ/mol   -39.0 kJ/mol   -1.17 kJ/mol
