EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic

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

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

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:

Carbon dioxide is the main pollutant that warms our planet Earth. Living things produce carbon dioxide when they breathe. However‚ carbon dioxide is considered to be a harmful pollutant when linked with any vehicle‚ trains‚ power plants‚ as well as other various human activities that involve burning fossil fuels such as gasoline and natural gas. Studies have shown that In the past 150 years‚ such activities have released enough carbon dioxide into the atmosphere to raise its levels higher than they
