2. Clean the magnesium ribbon with sandpaper. 3. Coil the ribbon and place it in the crucible. Weigh the crucible with its lid and the content in it.
and 226 A.D. The artifact is a 5-1/2-inch high clay vessel found inside of a copper cylindermade of a rolled-up copper sheet, which houses a single iron rod. At the top, the iron rod is isolated from the copper by bitumen plugs or stoppers, and both rod and cylinder fit snugly inside the opening of the jar, which bulges outward towards the middle.. Holding it together is asphalt. Within the vessel, an oxidized iron rod was located. Researchers stated that when filled with acid or alkaline liquid, an electric
Chlorine gas can be produced in the laboratory by adding concentrated hydrochloric acid to manganese(IV) oxide in the following reaction: MnO2(s) + 4HCl(aq) ( MnCl2(aq) + 2H2O(l) + Cl2(g) a. Calculate the mass of MnO2 needed to produce 25.0 g Of Cl2 ans: 30.7 g MnO2 b. What mass of MnCl2 is produced when 0.091 g of C12 is generated? ans: 0.16 g MnCl2 1. How many moles of ammonium sulfate can be made from the reaction of 30.0 mol of NH3 with H2SO4 according to the following equation: ans.
4. Howell iron works purchased came with a furnace which was named Howell Iron works then traditionally pig iron would be worked into wrought iron in finery forges and later putting the furnaces more recently into steel. In these processes, pig Iron is melted and a strong current of air is directed over it while it is being stirred or agitated. This cause the dissolved impurities to be thoroughly oxidized. An intermediate known as refined iron, refined metal, and refined iron.
Effect of Local Steel Slag as a Coarse Aggregate on Properties of Fly Ash Based-Geopolymer Concrete O. M. Omar, A. M. Heniegal, G. D. Abd Elhameed, H. A. Mohamadien Abstract—Local steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. Using local steel slag waste as a hundred substitutes of crushed stone in construction materials would resolve the environmental problems caused by the large-scale depletion of the natural sources of dolomite. This paper reports the experimental study to investigate the influence of a hundred replacement of dolomite as a coarse aggregate with local steel slag, on the fresh and hardened geopolymer concrete properties. The investigation includes traditional testing
It is used in the tips of drill bits, high speed cutting tools and in mining machinery. Tungsten disulfide (WS2) is a dry lubricant that can be used to temperatures as high as 500°C. Tungsten forms compounds with calcium and magnesium that have phosphorescent properties and are used in fluorescent light
Materials and Methods At the start of the lab, approximately grams of aluminum can pieces were weighed, recorded, and placed in a 250mL beaker. Next, 50 mL of 1.4 M KOH solution were added to the aluminum pieces in the beaker. During this reaction, a fume hood was used to vent the gas released by the reaction out of the laboratory. The reaction was sped up by slowly applying heat using a hot plate. An aspirator was set up in order to filter the mixture.

Because he was the Plant Manager that decides which new lift truck from a brand can be purchased. 2. Describe the important “needs” Columbia Industries has as they undertake the process to purchase seven new lift trucks. A: Columbia Industries is a company that was established in 1948 and grew to be the largest manufacturer of code-approved products. The first time that it came to their attention that there was a need for new lift trucks was when a complaint was submitted by the plant union leader about the safety and performance of the Hyster lift trucks.
Vershire Company is a diversified packing company. They are one of the largest manufacturers of aluminum beverage cans in the United States. They have a reporting structure where there is a divisional manager and two line managers that report to that manager. There were two vice presidents that headed all of the division’s activities in their functional areas. Outline the strengths and weaknesses of Vershire Company’s planning and control system.
