Please help me with number 4. I attached my lab results which are highlighted as well. Will give feedback :) 1) Part 1: In the following table organize the experimental data from the part 1 of the video. Include two decimals for all the volumes used (not shown in the video) + Table 1: Heat of neutralization of Strong Acid (HCI) and Strong Base (NaOH): Trial 1 Trial 2 Trial 3 22.00 C 22.30 C Initial Temperature 23.30 C of the solutions (C) acid 200 mL 300 mL 300 mL Volume of used (mL) Concentration acid (M) of 2.00 M 2.00 M 1.00 M Volume of base 200 ml used (mL) 250 ml 100 ml of 1.50 M 2.00 M 1.00 M Concentration base (M) 33.96 C 25.59 C Final temperature 33.16 C of mixture (C) 9.86 C 11.96 C 3.29 C Temperature Change AT("C) (Calculate) 2) Part 2: In the following table organize the experimental data from the part 2 of the video.
