Abstract This project was done to enhance an individual image through body scent. Past odour-related journals were analysed and found that the bacteria and mildew are the cause of the odour. Hence‚ this current study aims to investigate the effectiveness of the sunlight in removing the odour and mildew and finding alternatives in replacement of sunlight by using salt‚ vinegar and baking soda. In the experimental procedures‚ dynamo was added to five sweaty shirts. Salt‚ vinegar and baking

thermometer began to rise across the corn belt. In St Louis‚ Missouri‚ in the southern corn belt‚ the temperature in late June and early July climbed to 100F or higher 10 days in a row. For the past several weeks‚ the corn belt has been blanketed with dehydrating heat. Weekly drought maps published by the University of Nebraska show the drought-stricken area spreading across more and more of the country until‚ by mid-July‚ it engulfed virtually the entire corn belt.

ABSTRACT: The electrophilic aromatic substitution reaction is the attack of a benzene ring on an electrophilic species resulting in the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl
