A student obtained the time-temperature data shown in the table below after mixing the solutions in Question (1) above. What temperature should be reported for T_2? Assuming the same volumes of solutions in part (B) of the experiment, if T_1 was 23.1 degree C and T_2 was 35.8 degree C, how much heat was evolved (in kilo Joules)? Give the numeric answer (with correct sig figs) in the first blank, and the proper abbreviation for the unit in the second blank. Assuming the same volumes of solutions in part (B) of the experiment, if the molarities of HCI and NaOH solutions are 2.00 M, how many moles of water are produced by the acid-base reaction? Indicate the correct numerical answer in the first blank (with correct sig figs, of course, and including any leading zeroes before the decimal) and the proper abbreviated unit in the second blank.
