The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.

Atmospheric Pollution
In the atmosphere, the existence of large quantities of undesirable substances that could cause several health issues to living organisms and humans is atmospheric pollution. Air pollution is otherwise known to be atmospheric pollution. The presence of undesirable materials would also destruct the natural environment such as a change in climate, degradation of habitat, or depletion of ozone. Air pollution is generated by the natural processes and activities of humans.
Smokestack Scrubbers
Once we believe in the environment and remember the pollution-producing facets of it, we will consider the smoke-stacks scrubber to be a number of the worst offenders. Although this is often legally correct, smoke-stack scrubbers often have a big function in terms of keeping ground-level air pollutants- safe to breathe and assisting within the management of emissions.
