Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1.

Swimming Rejuvenating‚ the body mind and spirit…. Fitness development The fitness development of swimming can be classified into1 group and 2 sub-sections: Performing swimming regularly can help one in building cardio which is important for both weight loss and good cardiovascular health. When the workout is increased gradually by swimming strokes in the water‚ the heart rate and muscle activity is improved. This increases blood flow to your muscles‚ which results in more nutrients being delivered

Chapman et.al (2009) studied the local impact of hoisted point sources on late spring aerosol driving and cloud-aerosol cooperations‚ in northeastern North America‚ was studied by utilizing the WRF-Chem community model. The immediate impacts of mist concentrates on approaching sun powered radiation were recreated utilizing existing modules to relate aerosol sizes and chemical composition to airborne optical properties. Direct impacts were reenacted by including a prognostic treatment of cloud bead

CLASSIFICATION TESTS FOR ORGANIC HALIDES James Anand L. Regala‚ Sabrina Nicolle G. Sarte‚ Ann Michelle Siao‚ Michael Sibulo‚ Victoria Tan Group 8 2C Pharmacy Organic Chemistry Laboratory ABSTRACT This experiment is done to classify organic halides. Most organic halides are synthetic and are not flammable. One way to classify organic halides is by classifying its -carbon atom as primary‚ secondary or tertiary. If the -carbon is attached to one R group‚ it is then primary. If the -carbon is

Natural Dyes from Plants in Producing Colored Paste Abstract: Paste is a type of glue made from starch or dextrin‚ a starch product. This investigatory project shows that we can produce our own colored paste without spending much time and money and by performing simple steps. That’s why this Science Investigatory Project can help students save their money instead of spending it in buying expensive and commercialized colored glue. In addition‚ this colored paste can be an additional source of
