Acknowledgements I would like to thank my family for all of their support also I would like to thank all of my teachers for all of the encouragement and most of all I would like to thank god for keeping me calm with all the stress I had. Abstract The purpose of my project is to explain the processes of the water cycle‚ explain what it is‚ and to show the process of evaporation and what happens during this process.my procedure consist of placing the small container in the middle of the

Discharge of toxic matters (pesticides‚ toxic metals etc.) and their condensation in food chain may affect sensitive animals immediately; all living organisms may expire when the stream becomes unable to recover itself. 10. The water regime may change as a result of destruction of nature‚ unexpected floods may occur and

Organizational pattern: Chronological Intended Audience: My class Introduction: I. Attention Getting Device: Have any of you ever had your own house plants? They’re great for bringing a bit of the outdoors inside with you‚ but they can be easy to kill‚ on accident. All that watering and their demand for sunlight can be easy to forget about.

Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

transpiration. Water vapors gather in the atmosphere creating clouds with condensation. This is when precipitation forms and falls to Earth. After it falls to Earth and gathers back in the ground and bodies of water‚ the cycle begins again. As all Earth’s cycle coincide‚ heavy amounts C02 are evaporated into the atmosphere due to a tremendous amount of industrial plants. Once evaporated the CO2 is absorbed into condensation and released as precipitation (or what we call acid rain). This is a form

from bodies of water by the heat of the sun. The evaporated water rises through the atmosphere as a gas‚ or vapor. As the vapors rise they cool and turn back into tiny droplets of water which attach to each other forming clouds by the process of condensation. During precipitation‚ the water falls back to the earth in the form of rain‚ snow or sleet. Some of the water seeps into the earth to underground reservoirs‚ or aquifers (UOD‚ 2004). The rest of the water is runoff‚ and it flows back to the

oxygen over a palladium catalyst‚ in gas phase is shown below: 2 H3C–COOH + 2 C2H4 + O2 → 2 H3C–CO–O–CH=CH2 + 2 H2O Vinyl acetate synthesised is used for production of polyvinyl acetate. Acetic anhydride Acetic anhydride can be synthesized by condensation reaction of two molecules of acetic acid. The main process involves dehydration of acetic acid to give ketene at 700-750 °C. Ketene is thereafter reacted with acetic acid to obtain the anhydride: CH3CO2H → CH2=C=O + H2O CH3CO2H + CH2=C=O → (CH3CO)2O
