Lab 1- Measurements of a Table ABSTRACT: The purpose of this experiment was to determine the value of the acceleration of a free falling object and to describe the range of experimental values. Within the experiment the items used to help provide the conclusion that 2/3 or our values fell within the 9.62m/s^2- 9.78m/s^2 range was a Vernier data-collection interface‚ Logger Pro Application and the apparatus Photogate. The results found within the 30 trial periods were all precise

Laboratory Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know‚ identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to

Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement

Introduction to Chemical Systems in the Laboratory’1. Specifically‚ 1.90 grams of KCL was weighed in a 250ml beaker and dissolved in 25 ml of deionized water. This solution was then quantitatively transferred to a 250ml volumetric flask. Proper technique is needed for quantitative analysis. This transfer was done to ensure that there was no detectable KCl left in the beaker. After transferring the solution add 3 drops of AgNO3 to the rinsed beaked to check the completeness of the transfer. Now take

Lab Two; Chromatography of Food Dyes Jan Konig 28.04.2013 11:00am Chemistry 121‚ section DE Abstract: The second lab deals with the chromatography of food dyes which means you figure out what kind of compounds are used in a product like food color etc. by comparing the result to FD&C Food Dyes. You use six different food dyes‚ four food colors out of the store‚ two different Kool Aid powder and four different colors of candy like M&Ms you use for the chromatograph. At the end you try

Treatment of Results 1) What is the role of 0.25M sucrose as the medium for the fractionation process? Cold sucrose does not chemically react with cell organelles Due to the density and size of sucrose molecules‚ it is able to suspend pellets for configuration while providing a solution where the centrifugation can be better balanced Sucrose offers a liquid medium in which less dense fractions can be poured off as supernatant at the end of each centrifugation step. 0.25M sucrose solution
