Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above

Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

Cumberland Metal Industries: Engineered Products Division‚ 1980 October 21‚ 2013 CA by Yiwen Zhang Cumberland Metal Industries (CMI) is one of the largest metal manufacturers in the world. The company evolved from selling metal as a finished product to one that used it as a raw material‚ increasing sales from $250‚000 in 1963 to over $18‚500‚000 in 1979. Currently‚ CMI relies heavily on SlipSeal‚ which is used as a high-temperature sealant in automobiles. Although CMI dominates

Cumberland Metal Industry 1‚2- The first two questions will be gone through together in order to avoid confusion. Pricing is one of the most important elements to launch a product on the market. Mainly‚ because it is the only element‚ together with the marketing mix‚ that produces revenues. It is fundamental to set the right strategy in deciding and setting the price of a certain product to be sure that is fully understood and appreciated by customers in all its aspects and characteristics.

In January of 1980‚ Cumberland Metal Industries (CMI) had developed a new product for the pile driving industry. Its new pad‚ made of tightly curled metal‚ had the potential to break into an industry where little or no innovation was taking place. The CMI product testing showed great efficiency gains over the current standard asbestos product. The existing competition consisted of small firms‚ few of which had the knowledge or resources to design and develop new products. CMI seemed on the verge

Curled Metal Inc – Engineered Product Division Overview Cumberland Metal Industries (CMI) was a company which sold metal as raw material in other products. After the company had developed the product – Slip Seal that could meet the demanding specification of the automakers‚ it had grown rapidly over the past decade. The sales increased from $750‚000 in 1991 to over $55 million in 2007. However‚ the sales decreased from 61 million in 2006 to 55 million in 2007‚ a net decrease of 9.5%‚ the net

the identity of the metals‚ I was capable of deducing a definite‚ possible identity for the golden metal‚ however‚ I could not provide a definite‚ possible identity for the silver metal. Conversely‚ the results of the experiment themselves‚ whether volume‚ mass‚ or density‚ proved insufficient in my attempts to distinguish the identities of the metals. Thus‚ during the experiment‚ I also observed the color of the metals‚ and used these observations in my assessment of the metals. The five trials for

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of
