Question

Place a test tube in the test tube rack, and label it 3. Then follow these steps using your prepared solution:

1. Use the pipette to remove copper(II) sulfate solution from the volumetric flask, and measure out 10 milliliters in the
graduated cylinder. Transfer the 10 milliliters of solution from the graduated cylinder to test tube 3.
2. Record the temperature of the solution in the table provided.
3. Measure 0.25 gram of zinc powder into a weighing boat.
4. Pour the zinc powder into test tube 3.
5. Measure the final temperature of the solution in test tube 3. Watch the thermometer for a couple of minutes, and
record the highest temperature it reaches.
6. Calculate and record the difference of the initial and final temperatures in the table.

Answer

Answer 1

To complete the procedure, follow these steps: transfer copper(II) sulfate solution to test tube 3, record the temperature, add zinc powder, monitor and record the highest temperature reached, and calculate the temperature difference.

Step-by-step explanation:

To complete the procedure, you need to follow these steps:

1. Use a pipette to remove 10 milliliters of copper(II) sulfate solution from a volumetric flask and transfer it to test tube 3.
2. Record the temperature of the solution in test tube 3.
3. Measure 0.25 grams of zinc powder and pour it into test tube 3.
4. Monitor the temperature of the solution in test tube 3 and record the highest temperature it reaches.
5. Calculate and record the difference between the initial and final temperatures.
