I need help! Each run 1-4 needs to be graph separately like the sample above Showing Final temp and Initial temp. I had a hard time trying to graph it on execl. Please help with steps!

Experiment 12 137 Fig. 12-1 Temperature vs Time 34 32 30 final temperature = 32.7C 28 Temperature (degrees Celsius) 26 time of mixing = 3.5 min. 24 22 initial temperature = 18.2C 20 18 17 0 2 4 6 8 10 Time (min.) Graph the temperature on the vertical axis and the time on the horizontal axis. Extrapolate the data between 0 and 2.5 minutes using a straight edge to the 3.0 minute mark. Extrapolate the data between 3.5 and 9 minutes (or whenever you stopped) back to the 3.0 minute mark. Determine the temperature change between the two extrapolations at the 3.0 minute mark. Calculate the heat of neutralization and the molar heat of neutralization from the treatment that follows. For more experience with graphing techniques, perform Activity 36. Let: , heat of neutralization , = molar heat of neutralization At = temperature change of solution m, = mass of final solution C = specific heat of final solution a = number of moles of HCI , + m, C, ft = 0 , -m C, At , ,/a Hess's law can be used to calculate the molar heat of neutralization from literature values for heats of formation of HCl, NaOH, NaCl and H,O. These values and the specific heat needed for the calculations are in the table below. 2015 Cengage Leaming. All Rights Reserved.
