I. Abstract The experiment: Classification tests on Organic Compounds‚ allows the students to be familiarized with different classification tests used for identifying the different classes of organic compounds; examine unknown compounds using appropriate tests; and identify functional group of an organic compound based on the tests performed. Several organic compounds with different functional groups were tested to identify the functional groups present in the compound. n-heptane‚ pentene

The water fountain as we know it was first invented in the early 1906 and is credited to two men - Halsey Willard Taylor and Luther Haws. Haws patented the first drinking faucet in 1911. with the primary motivation being to provide safer drinking water and avoid the risk of typhoid fever caused by contaminated water. (Luther Haws’ father had died of typhoid fever precipitated by contaminated water.) From those humble beginnings‚ when water coolers used large blocks of ice to chill the water

Aerobic Treatment In the biological process‚ if the micro organisms (aerobes) use free or dissolved oxygen for the degradation of organic wastes‚ it is named as aerobic treatment. The availability of the oxygen for the working of aerobes as an electron acceptor accelerates the biodegradation significantly and maximized the treatment system capacity. Factors influence on treatment process The microorganisms and their growth are the driving force for the degradation process. To achieve a high rate

WATER QUALITY 1 Water Quality and Contamination SCI207: Dependence of Man on the Environment Water Quality and Contamination Abstract In this experiment water quality and contamination of groundwater were investigated. First‚ I will observe the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the largest quality of contamination to the water‚ while the laundry detergent will just create a bad smell to it. Considering

HYDRAULIC THEORY Introduction A hydraulic system is defined as a‚ ‘machinery unit which uses fluid as a pressure medium’. It has a number of advantages over an electrical system of a similar working capacity. Advantages: (1) The power to weight ratio is at least 14 times better than an equivalent electrical system. (2) Self-resetting overload protection. (3) Self-lubricating. (4) Infinitely variable speeds. (5) No static electricity. (6) Linear motion.

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods

Despite following rigorous experimental procedures‚ there are limitations that exist‚ but were not addressed due to insufficient time and limited resources to carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare

Free Radical Bulk Polymerization of Styrene This protocol describes the bulk polymerization of styrene at 60 oC using 2‚2´azobisisobutyronitril (AIBN) as an initiator. The monomer styrene first has to be purified before it can be used. The purification is performed in order to remove inhibitors and impurities‚ which can
