Graph 1‚ illustrates the pH of each quadrat. The pH in Quadrat 1 was more acidic than the pH in Quadrat 2‚ 3‚ and 4 this is due to the slope of the ground (refer to Graph 8)‚ different soil substrate and the decomposition of organic matter. As can be seen from Graph 8‚ the soil pH increased with a decrease in the slope of the ground. In Quadrat 1‚ the soil had a pH of 7.5 due to having a higher soil elevation of -8° in comparison to Quadrat 2‚ 3 and 4‚ in which the slope of the ground was -2°‚ -2°

Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This

product after they discover a new research about aerogel. They have been considered as a new development material that better than polyurethane foam in refrigerators‚ and as a heat insulator for windows. Aerogel is produced by removing all the water from a colloidal silica gel without collapse its overall structure. When gels get dry normal temperatures and pressures its affect the surface tension in tiny pores of the gel causes the structure to collapse and reduce itself to roughly 10 times its original
