Which of the following is not a common component of Photo-chemical smog? Correct Answer CFCs

Concept:

Photochemical Smog

  • Photochemical smog is found to be a mixture of pollutants that are formed when nitrogen oxide and volatile organic compounds react with sunlight thereby creating a brown haze.
  • This photochemical smog is the major contributor to air pollution. 
  • It develops when the primary pollutants (chemicals from fossil fuel combustion) interact with sunlight to produce a mixture of hazardous chemicals known as secondary pollutants.

Primary pollutants

  • The two major primary pollutants are nitrogen oxides and volatile organic compounds.
  • These primary pollutants combine react with sunlight and create secondary pollutants. 


Secondary pollutants

  • Secondary pollutants are ozone, peroxyacetyl nitrate (PAN). 

 

Among the given compounds CFCs is not a common component of Photochemical smog. 

CFCs ( chlorofluorocarbon) is a man-made compound, containing chlorine, fluorine and carbon. The most common emitter of CFCs is refrigerants.

Which one of the following is not a component of photochemical smog?
Which chemical below is a key component of photochemical smog?
You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
