Density Of Liquids And Solids Lab Report Essay

Lab 2 Report- Identification of Substances by Physical Properties The purpose of this lab was to see how certain substances; Naphthalene, Toulene, and and 2 unknowns (one liquid, one solid) react with 3 different solvents. To identify the two unknowns, testing needs to be done to find the density of both the liquid and the solid, determine the melting point of the solid, and the boiling point of the liquid. The Physical Properties of Pure Substances Table can then be used to compare the observed

Lab Report Experiment 1 & 2 CHM-101 Amele Takpara Partner: Jessamyn Dupree ------------------------------------------------- Experiment 1 ------------------------------------------------- (Pre-Lab Questions) 1. In the design of a Bunsen burner, explain the purpose of a. the gas control valve The gas control valve regulates the rate at which methane enters the burner. b. and the air vents. The air vents control the rate at which air enters the burner 2. Why is a luminous

Molecules in Solids, Liquids and Gasses Lab Report Introduction: Four experiments were conducted in this lab: measurement of atomic size in metal lead and zinc, finding the packing coefficient using lead shot, measurement of molecule size in water, and determination of an empty space percentage in gaseous CO2. We performed these experiments with simple measurement and calculation techniques to estimate the size of atoms and molecules of solids and liquid, and the empty space percentages of solids, liquids

CHE 151-50 Fall 2013 Lab report Isolating the Components of a Three Component Mixture The purpose of this experiment was to separate the component of three mixtures sand, sodium chloride and calcium carbonate then calculate the percentage by mass of each component recovered from the mixture. The other purpose of this experiment was to show us the students the concepts associated with physical and chemical properties of substances. Me and my lab partner, obtained a mixture of a un known

for the lab. Knowing the steps for the lab is extremely important because especially in chemistry if something is done out of order it can be dangerous. So recording the procedure in our lab book is important. This relates to my major of Political Science in that in Political Science, recording down things accurately is very important and if something isn’t recorded accurately it could be dangerous like in chemistry lab. In my lab report for the Density Lab I recorded the steps to the lab. The objective

TA will be able to help you. 3) Use the scientific database Reaxys accessed through the UK Libraries web site to search for your topic and locate a journal article on that subject. Write the full citation for the article in your lab notebook and include it in your report to turn in. 4) In your own words, write a brief summary of the journal article you chose. 1) Summary of Journal Article When dry ice is placed in water a thick, white fog forms. Being so easy to generate, this phenomenon is often

Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined

Jaynil Patel Lab Partners: Meghan Harbaugh and Chaimae Oualid TA: Prabani Dissanayake Title: Simple and Fractional Distillation of a Binary Mixture Introduction: Cyclohexane and Toluene are the two organic molecules that will go through the purification process. Both compounds are “colorless, flammable liquids, that dissolves with water” (Environmental protection Agency). The lab required using distillation, which is a process of separating liquids by cooling, heating, and condensing the

Aneri Patel CHEM 2100 Midterm Lab Report Fall 2017 Comar Unknown Number #####  Introduction: The main purpose of these experiments was introduce various techniques such as the use of separation, purification and extraction for each organic compound that was obtained. The first experiment was done on a compound which is commonly known as a triglyceride which contains three fatty acids and a glycerol backbone. The next experiment was done one a caffeine which is a hetercylic ring. However, this heterocyclic

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data
