Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

Lab report April 14‚ 2013 Abstract: In this article‚ we will experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs

Proving the Principles of Force I. Purpose: The purpose of this lab is best understood by the statement of that the net force is described as having a direct proportional relationship to acceleration while having an inverse relation to mass‚ this lab is performed to study the roles of these two variables in the real world and see firsthand how they play a role in net force as well as to test the following hypothesis. II. Hypothesis: If an Atwood machine is used to calculate acceleration on a pulley

The progress of the reaction was monitored in my case using two TLC plate. It first started off with the spotting of Standard benzoin and benzil which were provided in the lab and followed by the addition of the reaction mixture at once it starts changing colour/boiling‚ then at 10 and 20 mins into the reflux. Once all the necessary steps were spotted‚ the TLC plate was placed in in a beaker containing CH₂Cl₂(methylene chloride)‚ which was used as the developing solvent in this experiment. To check

Blackford St.‚ Indianapolis‚ IN 46202 This project was collaborated on by three different organic chemistry students‚ who individually synthesized and researched each of the three substitution reactions in this experiment.. The first reaction was an Sn2 reaction of 3-phenyl-1-propanol with NaBr and H2SO4 to create1-bromo-3-phenylpropane

A double displacement reaction is a type of chemical reaction in which two compounds react in order to create two new chemicals. The two cations and anions switch places with each other which forms two new compounds. As an example AB+CC can switch to AD+CB. Both sides of these equations must balance out in order to be neutral. So any pairs of compounds (such as A+B) must have a total balanced charge. In this example A could have a charge of positive 2 (+2) and B could have a charge of negative

Standards Addressed Lesson 13: Plate Tectonics I Overview Lesson 13 introduces students to geological oceanography by presenting the basic structure of the Earth and the properties of Earth’s primary layers. Students learn the structure and composition of oceanic and continental crust and the theory of plate tectonics. In the activity‚ students calculate the rate of movement of the Pacific Plate using information about the age of the Hawaiian Islands. Lesson Objectives Students will: 1. Describe

since a type II product is essentially the result of a homolytic cleavage of the Fe-S bond from a type I product.2 Type II products are not thermodynamically stable without a second equivalent of H2S‚ which complexes with the sulfide radical to create an H2S2•- species.2 This type of reaction can continue to create polysulfide chains.2 Lastly‚ type III reactions

Title: The affects of hydrogen peroxide on catalase reactions in animal and plant cells at different temperatures and states. Introduction: All living organisms in the kingdoms of life are composed of and depend on cells to function normally. Not all cells‚ however‚ are alike. There are two primary types of cells: eukaryotic and prokaryotic cells. Cells contain organelles‚ or tiny cellular structures‚ that carry out specific functions necessary for normal cellular operation. (Regina Bailey Updated
