Submitted: July 4‚ 2015 Date Performed: July 4‚ 2015 Lab Section: Chem-181DL1 Course Instructor: Prof. Amal Bassa Purpose The purpose of this experiment was to perform and observe the flame tests of some alkali and alkaline earth metal ions. Procedure To begin I placed approximately 0.5 mL of sodium nitrate in a well of the 24-well plate. I then placed approximately 0.5 mL of the remaining 6 solutions and the unknown in 7 other wells of my well plate. Then taking a cotton swab‚

4/29/2013 5.1 Lab Report - Identification of Metallic Ions TITLE: LAB 5.1 IDENTIFICATION OF METALLIC IONS PURPOSE: In this lab we are learning how to observe and perform “flame tests”‚ of alkali and alkaline earth metal ions. We will use basic lab equipment provided in our Labpaq‚ and follow all safety precautions in this lab. From reading the discussion and review‚ we understand that the normal configuration of the electrons is called “the ground state”. We understand that they are

Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

Metal Works Case study Project Summary- Metal-Works is a manufacturer of steel products such as steel safety boxes and cabinets. At present‚ the company has two existing manufacturing facilities in Delaware and Iowa. The new appointed CEO of Metal-Works Corporation wants to re-configure the network for the company. The present configuration is believed to not be optimum. As an initiative to improve this situation‚ the CEO has decided to hire a consultant to analyze the current distribution centers

melt or even vaporize metal. The melted metal is washed away by the dielectric. The sparks cut small‚ spherical shaped‚ cups into the surface. The surface is covered with recast (melted and resolidified) metal. Thus‚ there will always be a hard‚ brittle‚ surface layer on EDM part surfaces. What process would you recommend to make many small holes in a very hard alloy where the holes will be used for cooling and venting? Again‚ LBM is good for small holes in hard metals and since they are being

The “Cumber-Coil”: A Revolutionary Product for the Value-Conscious SITUATION ANALYSIS Cumberland Metals Industries developed a new type of cushion pad for pile drivers made of curled metal. The 11.5 inch “Cumber-Coil” was tested by two different companies on two different projects and was found to far exceed the performance of the existing market-dominant product‚ the asbestos pad. The Cumber-Coil weighed half what the asbestos pad did and boasted a 33% faster driving time‚ 60% reduction in

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

It wants to introduce a new high performing cushion pad into the pile-driving market. CMI will initially target small engineering/construction and independent pile-driving contractors. CMI will have the first-to-market advantage‚ as there are currently no direct competitors for metal pads. In terms of channels‚ CMI would distribute its pads through manufacturing representative

WHAT ARE CHALCOGELS? Chalcogels are a new type of aerogel that is chalcogen-based. Aerogels are a special type of material that presents a high surface area. Chalcogels are composed of metal-chalcogen moieties that are interconnected with a linking metal ion (Riley et al.‚2012). Figure 1 AeroGel INTRODUCING… TM Physical and Chemical Properties Chalcogels are a new family of aerogel that is not oxide-based (Katnatzidis and Bag‚ 2008). Zinc chalcogenide‚ like many other aerogels‚ have
