time(s) 30 60 120 180 240 300 420 480
t(*c) 13.8 13.8 13.9 13.1 14.2 14.3 14.5 14.7 14.8

b. if t1= 24.5*c, T2= 1.5*C, tr= 23.6*c, and with the tf obtained from the plot, determine Ccal, in J/*C, if the procedure descrived in the laboratory is followed.

3.when 0.600g of metal are added to 100.0mL of 3M HCL, the temperature rose from an initial temperature of 24.1*C to a final temperature of 32.6*C. Calculate the heat of reaction, in kJ/mol of metal, using the information given in the laboratory and assuming the heat capacity of the calorimeter is 32j/*C
