reunification‚ however‚ it faced severe economic problems and was due to be closed down. The meeting between the scientists and DKK Scharfenstein resulted in the birth of ’Greenfreeze’ technology for domestic refrigeration. Greenfreeze refrigerators use hydrocarbons for both the blowing of the insulation foam and the refrigerant and they are entirely free of ozone destroying and global warming chemicals. When DKK Scharfenstein announced their intention to mass produce "Greenfreeze"‚ Greenpeace successfully

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

mixtures of hydrocarbons‚ compounds which contain hydrogen and carbon atoms. In a “perfect” engine‚ oxygen in the air would convert all the hydrogen in the fuel to water and all the carbon in the fuel to carbon dioxide. Nitrogen in the air would remain unaffected. In reality‚ the combustion process cannot be “perfect‚” and automotive engines emit several types of pollutants.

hydrogen and carbon molecules called Hydrocarbons. Petroleum consists of hydrocarbon chains each has its own physical and chemical properties‚ and length determined by how many carbon molecule present in a hydrocarbon chain. For example‚ one to four carbons form gases like methane‚ ethane‚ propane‚ and butane. Five to seven carbons produce solvents like cleaning fluids and paint solvents; and seven to eleven carbons form gasoline and other similar fuels. Finally‚ hydrocarbon chains that consist of more than
