Ankit 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

I. BACKGROUND Precious metals and gemstones have been a popular investment vehicle especially in Asian countries and on the part of those who are constantly moving from one country to another. Asians have a special fondness for them because precious metals and gemstones have enabled them to survive hard times most especially when the super power waged their wars on our shores. Another reason for this is the presence of many gold deposits and mines in our country

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original

Case Study Finance - EDHEC MBAUnited Metal | | Background We refer to the case in the finance textbook for the details. Throughout our efforts in determining the right decision for United Metal‚ our team decided to calculate the difference between the ‘Make’ or ‘Buy’ options‚ using the numbers given in the case. However‚ in order to determine the net present value (NPV) and make appropriate recommendations‚ a risk adjusted discount rate (rate-of-return or ‘r’) needs to be incorporated.

CHAPTER 5 DISCUSSION 5.1 Analysis of Trace Metal by FAAS Based on the table (4.3 and 4.4) the trace elements was detected by using the flame atomic absorption spectrophotometry analysis. The trace metal can be detected by the FAAS within 15 seconds to 30 seconds of each soil sample. Before the samples were analysis with the FAAS‚ the blank samples were run in the machine for each element that was being analyzed. Their absorbances were read. The mean of each blank was calculated and

Introduction The purpose of this lab was to determine the percentage of chloride in an unknown soluble salt sample through a gravimetric method known as precipitation gravimetry. The objective was to accurately and precisely convert the unknown sample containing the chloride analyte to another known solid‚ silver chloride. Once the mass
