Society has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of 1973, Rowland and Molina discovered that CFCs can destroy...

The Ozone Layer After two decades of probing the atmosphere with a welter of instruments carried on spacecraft, weather balloons and highflying U-2 aircraft, researchers thought the case was closed: man-made chemicals known as chlorofluorocarbons (CFCs) drift into the stratosphere, break down and...

Ozone Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation...

About 90% of the ozone is in stratosphere, a layer between approximately 10 and 50 kilometres above the earths surface. The remaining 10% of the ozone is in troposphere, which extends from the Earth's surface up to about 10 kilometres. Ultraviolet radiation is a part of the sun of wavelengths. UV...

Chlorofluorocarbons (CFC) is a molecule made of chlorine, fluorine and carbon atoms. It¡s a stable but dangerous molecule. It used to be used in refrigerators, freezers and aerosol cans. It had been used as coolant in refrigerator propellants in aerosol sprays. It has been used as early as the 19...

The use of chlorofluorocarbons has always been a controversial issue. Like many elements and compounds, chlorofluorocarbons (CFCs) have benefits and drawbacks, and for this reason is why their use has been a topic of discussion. CFCs have various positive and negative impacts on the economy, the en...

Many in the world of science do not succeed as prominent individual considering it is a tough field not only to achieve in but to maintain an identity. Mario J. Molina was someone that prospered as a minority and Nobel Laureate in this particular field. Mario was a Mexican American chemist, born...
