functions each tree offers‚ besides its aesthetic addition‚ is the sequestering of CO2‚ carbon dioxide. To elaborate this importance‚ it is fair to paint the big picture. Heat is trapped in the earth’s atmosphere due to high levels of carbon dioxide (CO2) and other heat trapping gases which ultimately prohibit the heat from being released into space. This is what has caused the virulent phenomenon call “Greenhouse Effect.” Trees naturally remove CO2 from the atmosphere during the state of photosynthesis

Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

Investigating pH Aim: To demonstrate dissolved carbon dioxide changing the ph level of substances. Materials: * 2 beakers * 2 straws * Stop watch * Distilled water * Lime water * Litmus Paper Method: 1. Pour 100ml of Distilled water into the first beaker‚ and label said beaker. 2. Pour 100ml of Lime water into the second‚ also Label beaker. 3. Test the two liquids with litmus paper and note the ph level‚ before any carbon dioxide has been introduced. 4. Place a straw in each

06.05 Rate and Collision Theory: Assessment Instructions Investigation of the Rate of a Reaction Background: The reaction you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid)‚ citric acid‚ and sodium bicarbonate. As the tablet dissolves in water‚ the

A. Identification of Pollutant in the Atmosphere Carbon Dioxide Carbon Dioxide is a colorless gas having a faint‚ sharp odor and a sour taste; it is a minor component of Earth’s atmosphere formed in combustion of carbon-containing materials‚ in fermentation‚ and in respiration of animals and employed by plants in the photosynthesis of carbohydrates. Though living things emit carbon dioxide when they breathe‚ carbon dioxide is widely considered to be a pollutant when associated with cars‚ planes

DEFORESTATION INTRODUCTION: Deforestation‚ clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. Examples of deforestation include conversion of forestland to farms‚ ranches‚ or urban use. The term deforestation is often misused to describe any activity where all trees in an area are removed. However in temperate climates‚ the removal of all trees in an area in conformance with sustainable forestry practices—is correctly

Dracca became aware that one of its competitors‚ TrendBaby‚ Inc.‚ was soliciting information from one of Dracca’s employees‚ Bob Shumaster. Shumaster was apparently detailing product assembly information that was unique to Dracca and explaining to TrendBaby how this assembly strategy saved Dracca thousands of dollars each month. Dracca discovered that TrendBaby actually hired Shumaster to provide this information‚ and that Shumaster was using Dracca company computers to relay the proprietary information

continually until the trees grow collectively as a whole into a forest as planned. Need and importance of afforestation: Afforestation helps in addressing the environmental issues of the world‚ esp. in preventing further global warming and reversing the effects of global warming. It also helps in avoiding desertification. As the human needs grew by the population growth and advances in civilization people have been exploiting nature and converting forests into agricultural lands‚ mines‚ and industrial
