To complete the tables, you would follow the experimental procedures and record your measurements. Since no experimental data is provided, I will explain how to fill each table and calculate the required values. Step 1: Complete Table 1 (Titration) 2nd burette reading/ cm³: Record the final volume reading on the burette after the titration reaches the endpoint. 1st burette reading/ cm³: Record the initial volume reading on the burette before starting the titration. Titre: Calculate the volume of solution R used by subtracting the initial reading from the final reading. Titre = 2^nd burette reading - 1^st burette reading Perform this calculation for the Approximate, Accurate 1, and Accurate 2 trials. Mean titre t_1 =: Calculate the average of the accurate* titre values (usually Accurate 1 and Accurate 2, if they are concordant, meaning they are very close to each other, e.g., within ± 0.1 cm^3). Mean titre t_1 = Accurate 1 titre + Accurate 2 titre2 The final mean titre should be recorded to two decimal places. Step 2: Complete Table 2 (Thermochemistry) Volume of A in cm³: Record the volume of solution R used for each experiment number. Volume of B in cm³: Record the volume of solution S used for each experiment number. Temperature of A in °C: Record the initial temperature of solution R for each experiment. Temperature of B in °C: Record the initial temperature of solution S for each experiment. Highest temperature in °C: Record the maximum temperature reached after mixing solutions R and S for each experiment. Temperature change T/°C: Calculate the change in temperature for each experiment. This is the difference between the highest temperature reached and the average of the initial temperatures of solutions A and B. T = Highest temperature - ( Temperature of A + Temperature of B2 ) Record T to one decimal place. Without the actual experimental readings, the tables cannot be filled with numerical values.
