Question

I need help with question 1 and 2?

Experiment 1: Acid/Base Neutralization Obtain a coffee-cup calorimeter set and a thermometer from the cart. Measure out around 50 mL of 1.5 M ammonia in a graduated cylinder and record the exact value in your lab notebook. Place this into the calorimeter and measure its "initial temperature", recording the number in your lab notebook. Rinse the graduated cylinder and thermometer with distilled water, then measure out around 50 mL of 1.5 M hydrochloric acid in the cylinder. Record its exact volume and "initial temperature". The average of the two initial temperatures will serve as our initial temperature in the analysis calculations. Pour the hydrochloric acid into the calorimeter and begin stirring the mixture with the thermometer. Record a new temperature reading every ten seconds. You will want to record data for at least a minute after the temperature stops obviously rising so that we can calculate the amount of heat lost to the surroundings. Rinse the calorimeter, graduated cylinder and thermometer with distilled water and perform a second trail for this experiment. All waste can go down the drain. Experiment 2: Dissolving Ammonium Chloride Rinse the calorimeter, graduated cylinder, and thermometer with distilled water. Using the graduated cylinder, measure out around 100 mL of distilled water and pour it into the calorimeter. Record the exact amount of water added in your lab notebook. This may take two volume measurements if you have a 50 mL graduated cylinder. Use a plastic weigh boat to obtain around 4 grams of solid ammonium chloride. Record the exact mass in your notebook. Take the temperature of the water in the calorimeter and record this value as your initial temperature. Add the ammonium chloride to the calorimeter. Stir the water with the thermometer and take temperature readings every ten seconds. Record data for at least a minute after the temperature stops rising like you did in the previous experiment. Rinse the equipment and perform a second trial. All waste can go down the drain. After the final trial, rinse and dry the equipment and return it to the cart. If time allows, I strongly suggest using the remainder of the lab period to work on the non-excel portions of the lab. Alternatively, we may have lecture/group work following lab. If so, it will be likely be in 29-322 after everyone finishes the lab. Once you are finished, head across the hall to that room.
