Enzymatic activities of bioactive washing powder Title: Investigation of the amalyse activity f bioactive washing powder Objective: To investigate the amalyse activity of the two brands of bioactive washing powder – “Super clean” and “Magic power”. Principal: Amalyse can catalyse the breakdown of starch into maltose. In this practical‚ solutions of the 2 washing powders will be filled into 2 identical wells on the starch agar plate separately. Starch will be broken down by the amylase disused

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical

Types of Chemical Reactions Lab Intro/Purpose The purpose of this lab is to determine types of reactions with only the reactants and through observation. Through observing the experiments‚ one is able to see a visual of each type of reaction taking place and it gives them a better understanding of how chemical reactions work and what products they may form. Materials & Procedure Materials: * Wood Splints - Copper Sulfate * Sodium Sulfate - Copper Wire * Barium Chloride

If we break down the question the aim of the study would be to investigate and see if there is a relationship between age and the ability to generate ideas‚ and whether the results would be the same as the previous study where the younger participants seemed to generate more ideas than the older participants. The research would be based on finding out what happens rather than finding out why things happens‚ as the aim is to find out whether the younger participants do actually generate more ideas

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Honey powder goes by many names including granulated honey and dried honey. They all refer to honey that has been dehydrated to the point that it becomes a solid. High fructose honey tends to crystallize naturally and so it is likely that the use of honey powder has been around as long as humans have been consuming honey. Honey’s use has been documented all the way back to ancient Egypt where it was used as an important dietary supplement as well as for embalming bodies. There are cave paintings

Precipitates between Various Aqueous Solutions of Ionic Compounds 11/12/12 Background Information: A double replacement reaction is a chemical reaction that usually takes place between two aqueous ionic compounds. In the reaction‚ the cation of one compound replaces the other compound’s cation that yields two produce two new and different compounds. A precipitation reaction is a chemical reaction in which the formation of a solid‚ as one of the products‚ arises “when two solutions are mixed”(Zumdahl
