Solubility of CO2 in water Aim: To decarbonate a bottle of soft drink and find out the amount of CO2 in the drink. * Principle: The reaction between carbon dioxide and water is an example of an equilibrium reaction: Materials: * * 3 soft drink bottles (300ml) * 6g of salt (NaCl) * Triple beam balance scale * Thermometer * Digital scale * Watch glass * Electric hotplate Method: Standing up method 1. An unopened bottle of carbonated drink

Carbon Dioxide is a colorless‚ odorless gas that occurs in small quantities in the earth’s atmosphere naturally. The earth’s ocean‚ soil‚ plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a ’linear molecule’. Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to

Carbon fibre-reinforced carbon (aka carbon–carbon‚ abbreviated C/C) is a composite material consisting of carbon fibre reinforcement in a matrix of graphite. It was developed for the nose cones of intercontinental ballistic missiles‚ and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter. It has been used in the brake systems of Formula One racing cars since 1976; carbon–carbon brake discs and pads are a standard component of Formula One brake

Carbon Footprint briefly defined is the amount of CO2 left behind after any human activity. They can be classified into primary and secondary footprints. [ (McLean 2008) ] Primarily‚ it is the direct emission of CO2 from burning fossil fuels or any kind of fuels. They are considered the main and biggest source of CO2 emission‚ thus the having biggest Carbon Footprints. [ (McLean 2008) ] The CO2 emissions from all products and their life-cycles are considered as secondary footprints. The life-cycle

Carbon Footprint The term “carbon footprint” refers to the amount of carbon dioxide we emit into the air every year. C02 is produced by many sources and is the gas responsible for Global warming and alarming changes in our climate. As we use our resources‚ the negative impact on our environment increases. The more C02 emitted in the air the more our ozone layer is affected. C02 is a natural gas and is always being emitted and absorbed to and from the air. There is a certain amount of carbon

raising Earth’s overall temperature. Each can be linked through one key adversary‚ carbon dioxide. Rising CO2 levels are almost the sole reason temperatures are rising at such an alarming rate. Aside from water vapor‚ carbon dioxide is a chief ingredient in our Greenhouse Effect stew. It’s everywhere. It emits from our cars‚ it flies from our smokestacks‚ and it empties from our lungs. All of Earth is in consensus that CO2 levels must be lowered or even maintained at their present levels. Even with nearly

ABSTRACT We are in debt to Carbon Dioxide (CO2) and other green house gases for our presence on earth. As they help in stabilizing temperatures to levels sustainable for organic life – by what is known as green house effect. In modern times burning of fossil fuels like coal‚ oil‚ and natural gas combined with fast deforestation has led to unprecedented level of green house gas emission. Here came in to existence the concept of Carbon Emission Trading developed during the Kyoto Protocol in 1997

sINTRODUCTION What are Carbon Credits? A carbon credit (often called a carbon offset) is a financial instrument that represents a tonne of CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) removed or reduced from the atmosphere from an emission reduction project‚ which can be used‚ by governments‚ industry or private individuals to offset damaging carbon emissions that they are generating. How are Carbon Credits used? Carbon credits are associated with either removing existing CO2 or CO2e emissions

Many of them are disembodied technology as process of production‚ methods‚ and labour efficiency has been vastly improved. On the other hand because most production or technology

INTRODUCTION Since carbon dioxide concentration in the atmosphere is accumulating rapidly because of burning fossil fuel‚ coal‚ oil and natural gas for power generation‚ transportation‚ industrial and domestic uses‚ our earth has been facing global warming‚ sea level rising‚ flooding and other adverse changes which damage to our ecosystem. To address this challenge‚ we need to find out other alternative ways that do not produce carbon dioxide or that reduce the release of enormous amount of carbon dioxide gases
