Just as the depletion of stratospheric ozone today threatens life on earth today, its accumulation was one of the crucial processes that allowed life to develop in prehistoric times. you must have the correct sig figs.

3 o2 (g) > 2 o3 (g)
(a) express the rate of reaction in terms of the rate of disappearance of o2 and the rate of appearance of o3.
rate = (delta)[o2]/(delta)t and rate =)[o3]/(delta)t
(b) at a given instant, the rate of disappearance of o2 is 1.61 10-5 mol/ls. what is the rate of appearance of o3?
mol/ls

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.

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion
