Question

On a sunny day, ozone levels are ______ than on a cloudy day, because _____ is stronger. Complete the following chemical reaction cycle. Use chemical formulae, but do not format the subscripts (i.e., carbon dioxide = C02). For radicals, append (dot) without a space (i.e., hydroxyl radical OH. = OH(dot)). Also note that there are proper ways to write the formula for a particular substance: i.e., water vapor would NOT be OH21. Next, list two pairs of molecules that are converted into each other, but are never truly destroyed, in this cycle. Use the same chemical formula format as above: each pair should have the chemicals separated by a forward slash with no spaces (i.e., ozone and molecular oxygen would be O3/O2). The OH. radical can be considered the cleaning agent of the atmosphere because it reacts with ____________ molecule(s) in air, except (list three examples, by chemical formula): _______

Explanation / Answer

1. Ozone levels are higher on a sunnny day, than on a cloudy day, because sunlight(and hence temperature) is stronger.

2. CO + OH *----> H+ CO2

H* + O2 -----> H2O*

H2O* + NO ------> OH* + NO2

NO2 + hv ------>O + NO*

Molecules that are converted to each other are : NO/NO2 & H/OH

3. It reacts with all molecules in the air.
