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

well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration would be‚ the less time it would take for the filter paper discs to rise to the surface. 2. Experimental design. Independent variable – is the concentration of hydrogen

Gravimetric Analysis of SULFATE as Barium Sulfate. Objectives * To learn the techniques associated with gravimetric analysis. * To use stoichiometry to calculate the percentage by mass of sulfate in an unknown sulfate salt. Background Gravimetric analysis is a quantitative method for accurately determining the amount of a substance by selective precipitation of the substance from an aqueous solution. The precipitate is separated from the remaining aqueous solution by filtration and

It will also require a pill bug sample of at least twenty specimens‚ and a supply of filter paper to use as the moist and dry bedding for the pill bugs in the arenas. In similar animal behavior experiments more than one element are tested‚ as in (2008‚ 09). Pill Bug Lab. StudyMode.com. Retrieved 09‚ 2008 they tested the pill bugs movements

non-compliance of the final effluents are as follows: • Flow meters are not calibrated (incorrect flow readings) and this makes it difficult to optimize the plant with respect to flows into different modules‚ i.e. Activated Sludge plant and the trickling filter plant.” • Over aeration (due to the oversized aerator blades) taking place in the extended aeration basin causing excessive foaming in the biological reactor and final settling tank. • The internal Recycle Pumps in the aeration are not Variable
