2013 Carbon Footprint Until very recently‚ most people had never heard of a “carbon footprint.” Now‚ all of a sudden‚ the phrase is hard to avoid. In an age of slick slogans‚ fast fashions and fickle fads it’s easy to assume that this is just another quirky passing gimmick. But it could well be the most important concept of our time. A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow‚ Joanna. How to Reduce Your Carbon Footprint:

1 Measuring and calculating equilibrium constants Clearly‚ if the concentrations or pressures of all the components of a reaction are known‚ then the value of K can be found by simple substitution. Observing individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure

Topic 9 - The Carbon Cycle Aspects of the carbon cycle are similar to the hydrologic cycle because both are good examples of “Interactions between the systems". Textbook – topic not covered in text. http://www.windows2universe.org/earth/ The Carbon Cycle Neglecting the small amount of carbon (C) added to Earth by meteorite impacts‚ there is a fixed amount of carbon on Earth (~800‚000 billion tonnes). All living things are made of carbon but carbon is also a part of the ocean‚ air‚ and

due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot produced is actually carbon monoxide. Cyclohexane is a saturated hydrocarbon and cyclohexene

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level

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
