1. This experiment requires you to do 7 trials with varying amounts of Na©üCO©ý.
2. Take a clean 50 mL beaker from the Glassware shelf and place it on the workbench. This is beaker # 1.
3. Take a balance from the Tools shelf and drop it on the beaker. Record the mass of the empty beaker.
4. Add 20 mL of 3M H©üSO©þ to the beaker. Measure and record the mass of the beakers again.
5. Add Na©üCO©ý to each beaker in the following amounts:
(a) To the first beaker, add 1g Na©üCO©ý.
(b) To the second beaker, add 2g Na©üCO©ý.
(c) To the third beaker, add 4g Na©üCO©ý.
(d) To the fourth beaker, add 6g Na©üCO©ý.
(e) To the fifth beaker, add 8g Na©üCO©ý.
(f) To the sixth beaker, add 10g Na©üCO©ý.
(g) To the seventh beaker, add 12g Na©üCO©ý.
6. Bubbling of the CO©ü gas indicates that a reaction has taken place. Weigh and record the mass of the beaker and its contents now.
7. Click on the beaker and drag it to the recycle bin on the right side of the workbench. Click ?Yes? to recycle the beaker and its contents.
8. Repeat Steps 3-6 with a second, third, fourth, fifth, sixth and seventh beaker. Drag the balance onto the new beaker to measure its mass. Make sure that you use the right amount of Na©üCO©ý for each beaker as indicated in Step 5!

To complete Assignment 1 of Procedure 1, you need to record the amount of CO2 produced versus the amount of Na2CO3 used in each trial. Follow these steps:
1. Look at the amounts of Na2CO3 used in each beaker in Step 5 (a-g).
2. Record the mass of CO2 produced in each trial after the reaction has taken place in Step 6. This can be done by subtracting the mass of the beaker and its contents before the reaction from the mass after the reaction.
3. Create a table or chart with two columns - one for the amount of Na2CO3 used and the other for the mass of CO2 produced.
4. Fill in the table or chart with the recorded values from each trial.
5. Analyze the data and look for any patterns or relationships between the amount of Na2CO3 used and the mass of CO2 produced. This will help you determine the relationship between the two variables.
To complete Assignment 2 of Procedure 1, you need to discuss your results in terms of moles and determine if there is a linear relationship between the amount of Na2CO3 used and the amount of CO2 produced. Follow these steps:
1. Convert the mass of Na2CO3 used in each trial to moles. To do this, divide the mass of Na2CO3 by its molar mass (in grams per mole).
2. Convert the mass of CO2 produced in each trial to moles. To do this, divide the mass of CO2 by its molar mass (in grams per mole).
3. Create a new table or chart with two columns - one for the moles of Na2CO3 used and the other for the moles of CO2 produced.
4. Fill in the table or chart with the calculated values from each trial.
5. Analyze the data and look for any patterns or relationships between the moles of Na2CO3 used and the moles of CO2 produced.
6. Determine if there is a linear relationship between the two variables by graphing the data and seeing if it forms a straight line. Alternatively, you can calculate the correlation coefficient to determine the strength and direction of the relationship.
Remember to include your findings and conclusions in your report for both Assignment 1 and Assignment 2.
