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…
water molecules as strongly as the water molecules attract each other. It should contain a highly electronegative atom such as N or O or, even better, an N-H or an O-H bond, because they can form H-bonds to the water molecules. It will then be able to work its way among the water molecules (dissolve). Sugar and ethanol are covalent compounds that are soluble in water, because they contain O-H groups that can H-bond to the water. Nonpolar compounds like hydrocarbons have weak intermolecular…
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…
It is utilized to remove small precise flakes from a lithic or tool, as it is used to do more detail oriented work. Pressure flaking is also used to retouch tool. A point of bone or antler, or copper can be used to pressure flake. For this experiment I used a copper tipped pressure flaker that I made. When it came to pressure flaking Knife River Flint, it seemed…
molecules themselves in the skin. And in some countries it is still used as scalpels in hospitals. Later Steel became the main use for spear heads, forging a spear head although was not easy. It would start with some high carbon, low carbon, and pure iron into a crucible, that was capped off with a clay cap, completely sealed from oxygen. Then is put on the bottom base of the smelting forge, the forge is thus ignited and supplied consistently for 5-8 hours…
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…
In this experiment, I tested the effect of saltwater on the formation of rust on an iron nail. To test this, The first step was to fill each labeled cup with the correct ratio of salt to water. The ratios varied between groups which created different concentrations of salt for the different groups thereby constructing different levels of my independent variable. The next step was to record the initial mass of each nail and then place them in the cups. Then, the nails were left to soak in their…
