TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally‚ an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound‚ but also to establish its purity. To determine the melting point two

Title: Separation of a Mixture of Solids Purpose: Learn and demonstrate how to separate different ingredients from a mixture of solids using different methods based on the properties of each ingredient. Procedure: I weighed mixture and tools‚ and proceeded to begin separating each ingredient. I used a magnet to separate the iron from the mixture. Then I heated the mixture in water to get the non-soluble sand out. Then I filtered out the benzoic acid after cooling it into a crystal form

Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent of heat is the amount

The Effects of Using the Heat Shock Treatment to Deliver a Vector in Genetic Transformation Introduction: In this experiment we are testing what is required for E. coli to successfully grow on LB (Luria Broth) plates with ampicillin and determining if any genetic transformation has occurred. By combining +pGLO LB and ampicillin we should get an ampicillin resistant gene and by using –pGLO we should create a non-genetic resistant bacteria. The pGLO plasmid has the GFP (green fluorescent protein)

Heat Transfer Through Jacket Objective The objective of this example is to analyze heat transfer in a pilot plant using simulation models. The first step is to use pilot plant data to calculate heat transfer parameters. The second part involves using simulation models to examine the trade-off between jacket parameters and heating times. Process Description Assumptions: The stirred tank is assumed to be perfectly mixed. The contributions of agitator work‚ heat loss to environment

Set out the two clear plastic cups that came with the "Cool Blue Light Experiment Kit" (item # 3053439) from Edmund Scientific at scientificsonline.com Add one scoop each of luminol and perborate mixtures and a few copper sulfate crystals to each cup. Add a consistent amount of each chemical. Try to count the grains of copper sulfate so that you are adding close to the same amount to each reaction. As an option‚ premix the dry ingredients in a clean‚ dry container. Add enough luminol‚ perborate‚

Distilling a Mixture of Cyclohexane and Toluene Lab partner: Chemistry 211 2/08/12 Goal: The purpose of doing this experiment is to separate a sample of cyclohexane and toluene using simple miniscale distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are acquired during the distillation process. It is expected that cyclohexane boils and distils before toluene. By gathering these measurements will allow us to determine refractive index
