Assignments in Science Class X (Term II) 4 Carbon and its Compounds IMPORTANT NOTES 9. Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

FIBER-OPTIC COMMUNICATION Introduction Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic waves that is modulated to carry information. First developed in the 1970s‚ fiber-optic communication system have revolutionized the telecommunication industry and have played a major role in the advent of the information over age. Because of its advantages over electrical

one form. Carbon is one of the elements that contain many allotropes. Each allotrope of carbon has its own different properties. The allotropes of carbon are diamond‚ graphite‚ fullerenes‚ carbon nanotubes‚ carbon nanobuds‚ amorphous carbon‚ glassy carbon‚ lonsdaleite‚ and carbon nanofoam. Diamond is the best know allotrope of carbon. It is the hardest known natural mineral which makes it very rough. In the structure of the diamond‚ each carbon atom is covalently bonded to four other carbon atoms and

There are four types of fats. Although there are bad fats and better fats‚ they are necessary to support cell growth and give your body energy. The bad fats are saturated fats and trans fats which are more solid at room temperature like a stick of butter and trans fats are liquid such as vegetable oil. Theses fats raise bad cholesterol levels and clog arteries putting you at risk for heart disease. Monounsaturated fats and polyunsaturated fats are the better fats that can lower bad cholesterol

Fiber Optic Connector Assembly The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

Carbon is the fourth most abundant element found on Earth‚ and is essential to all life as we know it. It is found in all living substances‚ and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms‚ it can help form solid minerals (such “ limestone)‚ ‘squishy’ organisms (such as plants and animals)‚ and it can be dissolved in water. Carbon is also present in rocks‚ dissolved in rivers‚ lakes and oceans‚ and is in the atmosphere
