Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction

Eggs are a key ingredient used to make a foam. Investigate the functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to

Lab Report Experiment #3 Chemical Aspects of Life The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for

This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents

Experiment 7: A Study of Chemical Changes: Types of Chemical Reaction INTRODUCTION Chemical changes are results of chemical reactions. All chemical reactions involve a change in substance and a change in energy. They are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. There are different types of chemical reaction classified into 4 general types‚ namely‚ Synthesis‚ Decomposition

Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

Firms in the textile industry can compete using pricing or non-pricing strategies. Pricing strategies involves the use and manipulation of prices to increase market share and reduce potential and existing competition in the textile industry. Non pricing strategies on the other hand refer to all the alternatives‚ excluding price‚ that a firm uses to achieve the same objectives. One of the most common pricing strategies used in the textile industry is the use of limit pricing. This involves a firm
