Aluminium smelting

Before building the design that is best fit for the presentation, there was many models that had “failed”. To start off with, the first design to successfully float with 50 pennies for 20 seconds was Tyler’s design that was built with two pop cans and two sheets of aluminum paper (one is used to wrap the cans while the other is used to make a “cup” to hold the pennies). However, when the group weighed this in class, it was around 31 grams, which is 4.5 grams overweight (the requirement is 26.5 grams)

It has usually been my experience that a cocktail consumed everyday, anytime of day is an essential requirement for sanity. For those that imbibe, a cocktail can turn a bad day into a fabulous one. Last year I started a new job, sufficed to say I was happy and grateful but unimpressed, but it was a lot of money. What made everything chill was the bar located in the downstairs lobby of the hotel. Now, this bar was nothing to brag about, I mean it was not the famous Hotel Monteleone in New Orleans

Tungsten is a chemical element with atomic number 74 and symbol of W. The word tungsten comes from the language Swedish which means heavy stone. This is a rare, hard metal under normal conditions when it’s uncombined. Tungsten is found naturally on Earth only in chemical compounds. It was identified as a new element in 1781. Its ores contain wolframite and scheelite. The element is remarkable for its robustness. It has the highest melting point of all the elements. Also its high density of 19.3

“The Synthesis of alum crystals” Experimental 2 – The aim of the experiment is to prepare Alum (KAl(SO4)2.12H2O) from scrap aluminum. In order to speed up the reaction, the lacquer and paint of the scraped aluminum were cleaned and cut into smaller pieces and placed in a 250 ml beaker. After the addition of 50 ml of 1.4 M potassium hydroxide, the solution was heated for approximately 30 minutes. The color of the solution changes

: During each reaction, something happened. During reaction 1, after adding the nitric acid a red-brown gas was created. The copper first turned green after a few minutes turned into a blue solution. Reaction 2, When acid was added a blue precipitate formed. Reaction 3, when heated the solution turned into a black precipitate. I noticed that the darker particles were denser than water. Dark particles began to settle to the bottom. Reaction 4, Sulfuric acid dissolved the black precipitate back to

Objective: The purpose of this lab is to demonstrate that scrap aluminum can be broken down to be reused to make useful materials. That aluminum oxidizes easily. Materials: 2.0g aluminum scrap 250 ml beaker 60 ml 1.5 M KOH Glass wool plug 40 ml 9M H2SO4 Ethanol Safety: Normal PPE (personal protective equipment) is required, safety glasses, lab coat, and closed toed shoes. Procedure: Obtain approximately 2.0g of small pieces of aluminum scrap. Place aluminum scrap into a 250ml beaker. Record the

Introduction: The purpose of the experiment itself was to display and investigate aluminum recycling while having the opportunity to construct a balanced ionic equation as well as percent yields. Students are able to complete these steps while the reaction takes place in front of them. This abstract will cover the procedure, materials, and discuss the results yielded from heating aluminum pieces and combining them potassium hydroxide and water. The resulting compound included potassium hydroxide

Feasibility Study of Producing Potassium Alum via Aluminum Foil Lujia Cheng and Shalin Presgraves CHEM 1065, Experiment No.5, October 11, 2016 Abstract. Alum is one of the oldest and the most explored substance in human history. Dozens of ways were discovered to produce it. One way of synthesizing potassium alum was covered in this report. In this synthesis, aluminum foil, an everyday material, was the reactant. This synthesis includes two main steps. First, dissolves aluminum in potassium hydroxide

Aluminium is the most abundant metal in the earth’s crust which occupies 8.8% of its weight and it is most commonly used in water supplies, medicines (Yavuz et al. 2004), explosives, construction of siding, aircrafts and motor vehicles and in food industry as cans, packaging materials, kitchen utensils and vessels (Tuzen and Soylak 2008). Consequently, the environmental exposure of aluminum to human and other animals is obviously possible. This metal ion causes Parkinson’s disease, Alzheimer’s

Defining my project came as a challenge to me. I originally wanted to choose something that was similar to my partner, Brian’s, topic. After looking through my options and speaking to my partner I eventually gave up and chose to research a topic I had much more interest in. I ended up choosing commercial aviation and more specifically the selection process in which materials are chosen for the wings used in the commercial aircraft. With the goal of becoming an aerospace engineer, I felt this topic
