Thermochemistry - Determining a Hent of Reaction Determination #1 Determination 2 Mass of Empty 10-mL Graduated Cylinder (6) Volume of Reaction Solution in 10 mL Graduated Cylinder (ml) Mass of 10-mL Graduated Cylinder plus Solution (8) 26,739 26,819 8,54 mL 7.80mL 135.479 34.729 CALCULATIONS AND CONCLUSIONS 1. Prepare a temperature vs. time plot for both determinations (one plot per determination). Lise the sheets of graph paper on the next page, and be sure to properly scale and Tabel both axis. Lise a straight edge to create the mixing and extrapolation lines. Your plot should look similar to Figure 2 when it is complete. 2. Using your plots and extrapolation lines, determine the initial and final reaction temperatures for both determinations, and write these values in the table below: Determination 11 Determination #2 (C) 19.6°C 2016 TomCo28.8°C 29./ 3. Using the initial and final reaction temperatures, calculate the temperature chance (AT) for each determination. Show your murk, and write these wees in the table below: AT = Tfinal - Tinital 1)288-19.6=9.266 229.1-20.129 oc Determination 11 AT(") 9.2 Determination 32 goo 4. Using the mass and volume data collected in Stepoto-ID of the experiment, calculate the density (ing/mL) of the reaction solution. Show your work, and write the densities in the table below: Determination 1 Determination 2 Density mL) 8
