Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

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 Bond

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

Research Topic The introduction of a carbon tax in Australia would have implications for economic and environmental sustainability. Obviously in the longer term the aim of the tax is to promote environmental sustainability but in the short term there will be implications for economic sustainability for a range of businesses and households. Using a range of current sources including reports and newspaper articles discuss the short and longer term implications of a carbon tax for the tourism and hospitality

1. Choose an overpopulated country in the world. Describe its situation (use some statistics) and then find out if that country (or perhaps a United Nations program‚ or NGO program‚ is in place to the help in the resolution of the problems associated with the overcrowding. Rapid population growth during the 20th century helped shaped China’s society in a myriad of ways as China struggled with the breakdown of its dynastic structures‚ world wars‚ civil wars and the founding of a new

ASSIGNMENT: 1 SESSION: 2012/13 TUTOR: Stuart Allan WORD COUNT: 1‚891 Carbon fibre is a strong‚ yet light‚ reinforced polymer. Carbon fibres are used in applications where high strength and light weight are required. Carbon fibres can also be easily moulded into the desired shape. They are also chemically inert‚ resistant to heat‚ and do not expand under changing temperatures. Machining of carbon fibre materials can generate airborne particles. The potential health effects of

Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more popular to the scientists. Initially‚ it was the spectacularly

Carbon Dioxide from Cars U.S. states are beginning to attack another major source of global warming pollution besides power plants: your car. David Biello reports Cars in California offer a new kind of sticker shock this year: carbon. In addition to the familiar smog ratings‚ labels on new Cali cars rank them 1 to 10 based on greenhouse gas emissions. The best‚ a perfect 10‚ will emit less than 200 grams of greenhouse gases per mile. The bad ones more than 520. Vermont will also begin offering

Carbon Sink A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period. The process by which carbon sinks remove carbon dioxide (CO2) from the atmosphere is known as carbon sequestration. Public awareness of the significance of CO2 sinks has grown since passage of the Kyoto Protocol‚ which promotes their use as a form of carbon offset. The main natural sinks are: Absorption of carbon dioxide by the oceans
