Shingala Dr. Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that compose them

Purpose: The Purpose of this lab is to utilize‚ demonstrate and understand the various techniques and procedures used to gravimetric labs. For this particular lab we will utilize our scientific knowledge of related to gravimetric procedures to find the chloride content in an unknown soluble salt. Theory: Using our developed knowledge of the conservation of mass‚ solubility and precipitation it is possible (with some degree of error) to know the content of chlorine in a particular salt by dissolving

Lab Report Purpose: The purpose of this lab experiment was to learn about the different densities of different kinds of metal. We used pennies made out of different metals to determine this. After we gather the data‚ it’ll be used to determine the metal used. Hypothesis: In the lab‚ I expect that the pennies before 1982 would be heavier than those that are after 1983 because the metal was initially changed because the earlier pennies cost more to make. So I think that since the heavier metal was

decreased‚ so liquid was released from the potato‚ because the cells in the potato would have burst if even more was absorbed‚ whereas the length stayed the same. In Cylinder (B) the mass and length increased‚ which means the potato cells absorbed some Sodium Chloride (NaCl)‚ so the cells don’t shrivel up and die. For Cylinder 3 the mass and length also increased‚ like cylinder (B). The potato cells would have shrivelled up if water was released‚ so by absorbing more it avoided this. c.) The liquid that

Behavior of Gases and Absolute Zero Determination Lab Report Experiment 4 Introduction In this experiment we measured the relationship between temperature‚ volume‚ and pressure. Objectives: Conduct a set of experiments‚ each of which illustrates a gas law. Gather data to identify the gas law described by each activity. Complete the calculations necessary to evaluate the gas law in each activity. From your results‚ derive a single mathematical relationship that relates pressure‚ volume‚ and

Stoichiometry Lab Stoichiometry is the end result of adding up chemical elements that were involved in chemical reactions (http://dictionary.reference.com/browse/stoichiometry). The word stoichiometry was obtained from two greek words meaning element and measure. This explains the definition for the term. A chemist named Jeremias Benjamin Richter was the chemist responsible for first realizing what stoichiometry was (http://www.chemteam.info/Stoichiometry/What-is-Stoichiometry.html). In 1972

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

AP Bio Block B Photosynthesis Lab 12/6/12 Introduction: Photosynthesis is affected by light intensity‚ water‚ and temperature. Plants grow more abundantly because the weather is warm. Carbon Dioxide given off by animals is consumed by plants that replace the oxygen animals take it. Experimentation will help understanding how plants are vital because of the oxygen they release. If leaf disks in the experiment release oxygen‚ they will undergo photosynthesis and float. If
