Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24‚ 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in

A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

“MOTIVATION” Filipino people are religious human being. We usually seek for guidance from our Lord in every decision we will made so in relation to that our teacher decided to have a speaker that can motivate us spiritually‚ emotionally and to enlighten us by a word of god. Fr. Joel Eslabra was the 1st invited speaker. He is a priest who is willing to share the word of God and also can give us inspiration. Fr. Joel starts his discussion with an inspirational lecture about the word of god presented

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately
