SY 2012-2013 ABSTRACT The researchers formulated a pesticide that was made up of Chili (Capsicum frutescens)‚ Averrhoa bilimbi (Hedychium coronarium) and Eucalyptus (Eucalyptus Globus). Well eventually here in our country‚ many pests are everywhere like in drainages‚ manholes‚ old houses and streets. The researchers’ purposes for this project are to eliminate and control

ABSTRACT ABSTRACT The researchers conducted a study about Kamias (Averrhoa bilimbi) and Dalandan (Citrus aurantium) as alternative decolorizers in Gram Staining bacteria. Kamias (Averrhoa bilimbi) has a high oxalic acid content‚ fruit used to remove stains from clothing and for washing hands‚ removing rust and stains from metal blades. Dalandan (Citrus aurantium) is an aromatic variety

LITERATURE The bilimbi‚ Averrhoa bilimbi‚ L.‚ (Oxalidaceae)‚ is closely alliedto the carambola but quite different in appearance‚ manner of fruiting‚flavor and uses. The only strictly English names are "cucumber tree"and "tree sorrel"‚ bestowed by the British in colonial times. "Bilimbi" isthe common name in India and has become widely used.Bilimbisare all much the same wherever they are grown‚ but P.J.Wester reported that a form with sweet fruits had been discovered inthe Philippines. The bilimbi is a tropical

Bleach – And How It Works! Yes‚ knowing how bleach works isn’t all that exciting‚ but since bleach is what you usually use in your daily life‚ why not understand how and why it works? Wonder how the colour of the liquid is a yellowish colour‚ but the clothes come out as pure white? Or maybe why your parents always tell you not to touch bleach because it harms your skin? Since we’re still young‚ why not understand it earlier? Bleach has two forms: chlorine bleach and non-chlorine bleach.

Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were able to be determined also using Beer’s law. From here the rate constant was able to be calculated for each concentration and the average was 0.599M/s. Overall‚ the Rate Law=0.14[dye]1[bleach]0. Trends in the date show when concentrations of the dye and bleach were at their fullest‚ the rate constant was lower and the change in absorbance

Solar bottled light bulb is easy to assemble and the procedure use‚ in an empty clear container of soda‚ add at least 1.5 liter mineral water and 2tblespoon of liquid bleach‚ with that it will be covered half of roof sheet and exposed to sunlight. The bottle is inserted halfway through a hole drilled in the metal roof and its sides are sealed. The whole deal looks like a bulb through a sunroof and provides a good amount

To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order.
