During an investigation, similar glow sticks were placed in two beakers containing water at different temperatures. A record of the investigation is shown below: Investigation Record
Glow Stick Beaker Water
Temperature Duration of Glow Stick in
the Beaker
A 50 °F 2 minutes
B 140 °F 2 minutes

When the glow sticks were bent, chemicals inside reacted to produce a glow. Which statement is most likely correct?
Stick A glows brighter as the rate of reaction inside it is higher.
Stick A glows brighter as the rate of reaction inside it is lower.
Stick B glows brighter as the molecules inside it move faster.
Stick B glows brighter as the molecules inside it move slower.

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
