Question

When starting the experiment, you and your partner are heating your flask in a 50 ºC water bath. You have waited about 5 minutes and feel like it's at the correct temperature. You remove the flask and add a whole Alka Seltzer tablet. You look in the flask to make sure that it is reacting, using about 30 sec of your time, and then a baloon to the top. You record the time from that point, pinch off the baloon and tie it. Choose the options that best describes way to correct incorrect actions in this scenerio.

1.Begin timing as soon as the baloon is added to the top of the flask.

2.Measure the temperature of the water inside the flask to determine if it has reached the correct temperature.

3.Wait 10-15 minutes for the temparature to reach the desired value.

4.Ten seconds after the baloon as been added, pinch, twist and tie off the baloon for volume measurement.

5.Add baloon immediately to the top of the flask to capure as much as the gas as possible.

6.Measure 20 seconds from adding the baloon, pinch, twist and tie off balloon for measuring volume.

7.Keep flask in the water bath while the Alka Seltzer tablet is added.

8.Break the Alka Seltzer tablet into pieces before adding to the flask.

9.Heat all flasks to 100 ºC to determine the reaction rate.
