Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the flame test

contain high level of toxic pollutants such heavy metals which are mainly produced by anthropogenic activities such as smelting‚ battery and steel manufacturing‚ mining‚ and metal processing (Verma and Dwivedi‚ 2013). The pollution caused by the release of these heavy metals into the aquatic system has become one of the major problems over the last few decades. In fact‚ some inland water bodies in Europe and America were closed for fishing due to heavy metal contamination (Vieira and Volesky‚ 2000). In

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

Case: Curled Metal Inc. (CMI) Introduction Curled Metal Inc. originally sold metal as a finished good but has later developed its business concept to transforming metals into high value added manufactured products. Early in 2008‚ the company was about to launch a new product‚ which could revolutionize its business‚ setting a new standard in the pile-driving market: CMI cushion pads. However‚ this product launch poses key strategic issues to the company‚ ranging from assessing manufacturing capacity

The resulting resins show good properties for the removal and even recovery of heavy-metal ions from their aqueous solutions or wastewater [33].

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

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‚

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

Plutonium Essay I would like to work on the metal plutonium because the discovery of plutonium has a great impact on the world. Plutonium’s symbol is Pu and its atomic number is 94. This element has 150 neutrons and 94 protons and its standard atomic weigh is 244. Plutonium is located in the 7th period and it is a silvery white metal. One of its main uses is to act as the fuel of nuclear fission Plutonium does not exist naturally‚ although some say that small
