How to fill out heats of reaction lab

How to fill out a heats of reaction lab:

1. Start by gathering all necessary materials and equipment for the lab, including a calorimeter, thermometer, chemicals, and a stir plate.
2. Begin by preparing the reactants according to the instructions provided. Measure out the required amounts of each chemical and ensure they are properly labeled.
3. Set up the calorimeter by filling it with a known quantity of water. This will serve as the solvent for the reaction.
4. Carefully measure and record the initial temperature of the water in the calorimeter using a thermometer.
5. Add the reactants to the calorimeter and quickly stir the mixture to ensure uniformity. Note the time of reaction initiation.
6. Monitor the temperature change of the reaction mixture over a specified time period. Record the temperature at regular intervals, such as every minute, for accurate data collection.
7. Once the reaction has reached its endpoint or has stabilized, record the final temperature of the reaction mixture.
8. Calculate the heat change of the reaction by using the equation Q = mcΔT, where Q represents the heat change, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the temperature change.
9. Repeat the procedure for any additional reactions or trials to obtain reliable data.
