Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism‚ the means by which animals derive the energy needed to sustain life. Furthermore‚ oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores‚ earths‚ rocks‚ and gemstones‚ as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the periodic

Preliminary Test and Solubility Classification of Organic Compound Keene Louise Topacio‚ Christopher Jay Robidillo Abstract The experiment focuses on how to classify organic compounds by its functional groups. It is done by preliminary test and with the solubility test. Preliminary test used two known compounds also the unknowns. Physical state‚ color‚ odor‚ and ignition test were noted. The known compounds are inorganic and organic compounds. A comparison is made from the observation in the unknown

of percentage of t-butyl chloride II. Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom is then replaced by a halogen (F‚ Cl‚ Br‚ I). Therefore‚ alkyl halides are compounds that have a halogen atom bonded to a saturated‚ sp3 hybridized carbon atom. These could be classified according to the number of alkyl groups attached to the carbon that is bonded to the halogen atom. A methyl halide does not contain any alkyl group

University of Santo Tomas Faculty of Pharmacy EFFECT OF pH ON ENZYMATIC ACTIVITY Abogado‚ Paula Isabel‚ Agustin‚ Nikka Rebecca‚ Andres‚ Mary Anne B.‚ *Austria‚ Beatrice April‚ Baybay‚ Jan Miko Aaron 2BMT I. ABSTRACT pH greatly affects the activity of enzymes. There is a point or pH level where maximum activity of enzyme can be achieved‚ this is called optimum pH. Invertase was extracted from yeast and used as the detanured enzymes. Two sets of six test tubes were each added with different

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‚ benzene‚ heptanol

------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the

Notes on Ball Bearings Bearing Nomenclature You can learn a lot about a bearing just from its part number. A typical bearing is the 6203ZZ bearing. This part number can be divided into it ’s components: 6203ZZ which means: Type Code Series Bore Suffix The type code indicates the type of bearing. While each manufacturer uses their own numbers‚ there are a few numbers that could be considered standard in the industry. Self-Aligning Ball Bearing This kind of ball bearing has a spherical outer race
