Why must Molina and Rowland’s data in the laboratory be supported by measurements taken in the stratosphere?

Thinking CriticallyWhy must Molina and Rowland's data in the laboratory be supported by measurements taken in the stratosphere. They must support it with data and make sure that what they have is precise and correct, so they can get the quantitate and qualitative data for the lab.

The changes you see with your eyes begin with changes at the submicroscopic level. Models enable chemists to understand difficult concepts that they cannot normally see.

there are different branches of chemistry because so many different types of matter exist, so there are many areas of study. ... it is important because chemistry seeks to explain the submicroscopic events that lead to macroscopic observations.
