  • Importance Of Inhibition Efficiency Of Polymers

    these properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years that can inhibit the corrosion rate of metal alloys but cost effectiveness, toxicity, processibility and other factors limit the applications1. The need for new, eco-friendly and cost effective…

  • Reaction Between The Calcium Chloride And Phhenol Red

    responsible for the high temperature change in the overall reaction. After doing a control experiment with Sodium Bicarbonate and phenol red and noticing that the temperature got colder, only one other chemical mixed with phenol red could be responsible for the warm temperature change that chemical being Calcium Chloride. There was a temperature change that was observed during the individual control labs as seen when calcium chloride was mixed with water it became hotter and when calcium…

  • Effect Of Temperature And Substrate Concentration On Catalase Reactions

    Effect of Temperature and Substrate Concentration on Catalase Reactions Blake Devivo Biol 101 Lab February 10, 2016 Abstract The human body contains thousands of tiny structures called enzymes that perform specific functions. One enzyme called “Catalase” is often used to regulate the amount of a toxic compound, hydrogen peroxide, in the body. The purpose of this experiment was find the different factors that can affect Catalase-Peroxide reactions. The first part of this experiment…

  • The Importance Of Reactive Intermediate

    Aeshah Alrubayyi CHM 643 Reactive intermediate has been important investigated in physical organic chemistry. It classes to carbocations, carbenes, carbanions and free radicals. Recently, observable intermediate classified as reactive, and an unobservable intermediate is kinetically when occurs at a branch point in a mechanism. A reactive intermediate is formed in the rate determining step of a reaction and then goes to give products in low barrier. Also, the hydrocarbon reaction of terminal…

  • Essay On Effect Of Temperature On Rate Of Reaction

    affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent: -the rate of…

  • Chemical Reaction In Cooking Food

    Chemical Reaction A Chemical Reaction is when there is change from physical reaction to nuclear reaction. In chemical reaction, there is also a change of a chemical substance to another, which in that case is the change to one or more productions. It 's when a substance changes and when you combine chemicals or mix them, you 'll most likely create a new one, not always but most of the time it will. Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the…
