An experiment was run to determine which enzyme (pectinase‚ and cellulase or combinations of the two enzymes) maximizes juice production and would be most cost effective. The proposed hypothesis was if the enzyme‚ pectinase‚ is added to apple juice‚ then the more juice will be extracted than if cellulase were added because pectinase holds the cell wall together and if it is separated apart from each other‚ then the more juice would be able to flow out. The experimental data show that during the ten

BACKGROUND OF THE STUDY Pest insects are based on the potential damage on human purpose. They cause damage to the agricultural crops‚ consume and or damage harvested food‚ cause illness or unproductively to agricultural animals‚ and vector human disease. For centuries man had made innovative ways in combining pest insects‚ which leads to the invention of insecticides. Though insecticides contributed big in the elimination of pest insects‚ it also contributed ecological alteration due to its toxic

Amanda Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric

This time we used a 150mL beaker‚ analytical balance‚ forceps‚ a 50mL graduated cylinder‚ a glass rod‚ beaker tongs‚ a hot plate‚ two 16 x 125-mm test tubes‚ centrifuge‚ a medicine dropper‚ a filter paper‚ a filter funnel‚ a 250-mL Erlenmeyer flask‚ a watch glass‚ a drying oven‚ a spatula and a red litmus paper. The chemicals we need were 20mL of 2.0M HCl‚ a calcium-enriched tablet and 25mL of 1.0M Na2CO3 solution.

acetate. By using Fischer reaction‚ Isoamyl acetate was produced by refluxing isoamyl alchol and acetic anhydride with the presence of sulfuric acid for 30 minutes. After cooling the mixture‚ cold water was added and it was transferred in a separatory funnel. It was then extracted with immiscible saturated sodium bicarbonate to hasten separation. The sodium bicarbonate layer was discarded and the organic layer was again extracted with sodium chloride to remove the acid. The sodium chloride layer was discarded
