EXPERIMENT 3 GROUP B AIM: To find the overall efficiency of plate column operating under total reflux, for a binary system (iso-propanol & n- propanol). APPARATUS: * Distillation Column with reboiler * Automatic digital refractometer * Two fluids with different volatilities. PROCEDURE: * Distillation column was filled with the two fluids. * Then we switched on the heater and set the temperature to 126.6 ̊C * And then we allow the system to reach the equilibrium.

coral as a food source. Another very degraded ecosystem good is fresh water, this is because of a process called eutrophication. Fertilizers are commonly used in the agricultural industry, however the run off from the fertilizers find their way into nearby water systems which pollutes the fresh water, thus the whole ecosystem declines. Also, the plants near the water system overgrows which blocks sunlight from getting into the water, so photosynthesis cannot occur in the aquatic plants so they do not

Describe and Explain what rejuvenation is and the effect rejuvenation has on the river. Rejuvenation is when a river has to readjust itself and the land around it, usually by increasing the amount of vertical erosion it carries out to a change in the base level. It is caused by various factors, including river capture, isostatic sea level change and eustatic sea level change. Due to it changing its processes, a river undergoing rejuvenation creates many new landforms. A river is said to be rejuvenated when

therapies should be integrated with conventional treatment and not only as a last resort. One such therapy is with dichloroacetate (DCA) which is sodium salt from dichloroacetic acid obtained as a by-product of the chlorination of municipal drinking water. It is an inexpensive and nearly harmless chemical which has also been used for the treatment of diabetes in the last twenty years. In 2007, University of Alberta discovered that DCA causes death of cancer cells without affecting the healthy cells

Most people know that a flour and water mixture is used to make paper mache, but are completely unaware that you can make even regular "Elmer's" glue using three everyday kitchen ingredients. We discovered this recipe on a solar cooking site, used it successfully in my new and improved solar cooker (plans and pictures coming very soon!) and also in place of regular school glue for crafts and projects. In scientific tests, this glue has proven to be just as strong as regular white glue, so you don't

surprising number of things you can use it for, here are the top 10 uses of baking soda: Baking soda is made from soda ash, and is slightly alkaline and neutralizes acid-based odors in water, and absorbs odors from the air. * Drain cleaner: Pour one cup down the drain followed by three cups of boiling water. * Use it as an antacid. * Chemical smells out of clothes: Soak clothes for two to three hours or overnight, in one cup of baking soda. * Use it as underarm deodorant by applying

Get an unopened bottle of water, most preferably purified or distilled water. If you live where the temperature outside is below freezing put the bottle of water outside and for about 3 hours, otherwise just put the bottle of water in your freezer for about two and a half hours (the time varies according to your freezer's size and output and the temperature you set it to.) Carefully take the bottle of water. If it is frozen, then that is a sign of failure. Shake the bottle a few times until

further heat after the air is warmed. The fan, by circulating the air, removes the heated air from close to the body and replaces it with cooler air. Likewise, the body is also cooled by evaporation of water from the skin. As the relative humidity of the air close to the body increases, less water can be evaporated, and cooling by evaporation is decreased. The fan, by circulating the air, removes the humid air from

of the seven samples. The room temperature and the water used were both at 72°F. The salt used to create the samples was supplied by Carolina Biological Supply Company. The seven ranging salinities were prepared in 100 mL samples. Seven masses of salt were measured on a scale (0g, 3.5g, 5g, 7.5g, 10g, 12.5g, and 15g) and were corresponded to a beaker filled with 100 mL of distilled water. For each sample, four trials were replicated by filling 30 mL plastic

of shell fish such as perch, croaker, and anchovies but primarily oysters. Being the largest estuarine system in the United States, the importance of maintaining that ecosystem is at an all time high. The EPA reports that over half of the fresh water entering the estuarine in the Middle Atlantic Region. (epa.gov, 2014) There have been a decrease in the ecosystems ability to maintain the native oyster population due to several reasons. Over fishing has been one of the causes of this. (Cerco
