incorrectly labeling the iron content on their products. The purpose of this experiment was to analyze the amount of iron in approximately one serving of Total Whole Grain cereal and in one iron tablet and determine if these accusations were true. The values collected would then be compared to the actual values for these products. Total cereal contains 100% of the recommended daily allowance for iron, and the iron tablet contains 361% of the recommended daily allowance for iron. The actual…
In architecture and civil engineering, sustainability plays a main role. All buildings and any construction could be potentially dangerous if they were built or designed in an inappropriate way. All structures and designs have to be safe and stable to prevent the fatal catastrophe of failing construction. The construction of any large objects, such as shopping centers, cathedrals, bridges, and other usually takes a lot of time. There are many forces that affect the designed construction and…
The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be…
their stone and copper predecessors because they could make stronger, longer, and sharper swords. Steel requires large amounts of iron ore, carbon, fast-flowing water, and a long lasting fire. It was created by smelting the iron ore and carbon together in a very hot fire. The Inca didn't have steel because they could not build a long enough lasting fire to heat the iron due to their wet climate. This affected their development because they didn't have strong weapons to take over other…
Part 1: Test of Melting Point Generally, ionic solids have very high melting point temperatures. Covalent molecules have a lower melting point. Polar covalent molecules have a higher melting point than non-polar covalent molecules. 1. Mold an aluminum foil boat that will serve as a tray for the table salt, sugar, wax. 2. At different corners of the boat place a very small amount of each substance. a. Table Salt b. Sugar c. Wax 3. Set the hot plate on high. 4. Observe and record the order…
Mineralization is independent of igneous processes. Host rocks comprise two types: calcareous or dolomitic siltstone, shale, and carbonate rocks of marine or lacustrine origin; and non marine sandstone, arkose, and conglomerate. In addition, the iron oxide copper-gold and basaltic copper deposit sub models may be applicable within some of the areas studied. Deposits of the reduced-facies subtype (model 30b.1; Cox and others, 2003), also termed coppershale or stratiform copper deposits, are…
Ceramics material are compounds between metallic and non-metallic elements where it most frequently oxides, nitrides, and carbides(William D.callister,JR, David G. Rethwisch,2015). This material use for technical applications are commonly based on aluminium oxide. The properties of ceramics which are insulative to the passage of heat and electricity and more resistant to high temperature and harsh environment(William D.callister,JR, David G. Rethwisch,2015). Ceramics in cochlear implants use for…
When heat is applied to an object, that object usually undergoes a structural change. This also applies to rock. Since Knife River Flint is a fine-grained stone the changes predictably would be minor, compared to a coarse-gained stone that would exhibit greater change when it came to thermal altering. Ahler purposed “that fine-grained cherts respond to heat alteration at lower temperatures than do coarse-grained cherts” (Ahler 1983: 2) which Knife River Flint is a fine-grained chert, so it…
First Mineral: My first mineral of choice is Titanium. Titanium is a metal that was discovered in 1791 by William Gregor. A few common properties are its low density, inflexibility, resistant to extreme temperature, and corrosion. Ti is titanium chemical formula. Titanium is vital in my everyday uses for instance my newly purchased wallet, Apple laptop that I use for school and the golf cart I drive around the park. Dentist use titanium for patients who receive teeth implants. Titanium powder…
Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less…
