The Components Of The Alloys

It is necessary to identify the identity of two unknown metals. This is important because a metal scrap yard must know the identities of the metals before they can be recycled. It is also necessary to know what each metal is if a building is to be made using one or more of these metals. Identifying the metals will be done using intensive properties. Intensive properties do not depend on the amount of material present. Density is an intensive property found with the formula D=m/v. Which is defined as mass divided by volume to find the density.

Add some drops of biuret solution into the watch glass. Record if it reacts or not.

The quality of the study will depend on how carefully the researchers entered the data into software programs and verified its correctness. Verification can occur visually or by entering the data twice. Cleaning the data involves the identification of possible outliers by looking at the frequency distribution of the data in a graphical format, such as a scatterplot, followed by testing suspected outliers statistically. Visual inspection of the data should also reveal the presence of wild codes, which are values that make no sense. The data in its final form must therefore be verified for correctness and cleaned of outliers and wild codes.

A few metal elements in high temperatures may enter an excited state and they’re seen by emitting a light of color. Comparing the substance flame with the flames of the reference table will help identify the element of the unknown metal. First we placed each of the liquefied metals in flames and observing their color changes by collecting data. Lastly, observing the color of the liquefied metal, placing it in the flame with a wire loop could emit a color change and this concludes the experiment. The unknown metal was exactly the metal ion that was hypothesized. The unknown metal

The three elements that I will be looking at are Krypton, Arsenic, and Potassium. These elements are all very different but share some similarities even with their separate placement on the periodic table. I chose these elements because they are the most different of the six elements that I chose to do this project on. Arsenic is the first element we will be looking at. Arsenic is a metalloid because it shares some characteristics with metals and some with nonmetals.

Around the world, we the people, are surrounded by numerous minerals that we might not even be aware of. After researching the minerals sulfur and anapaite, I have come to a conclusion that minerals are an engaging topic to dig into. The two minerals I analyzed had both similar and different qualities. While examining the minerals by using specific character traits I discovered interesting data on each substance.

The purpose of this lab was to review the techniques for measuring mass and volume. Also using raw data to calculate the density of each of the metal samples. The final objective was to compare the density values with the values on the reference tables and calculate percent error.

(20) Metals are classified variously—according to molecular weight (“heavy metals”), according to chemical properties (periodic table), according to toxicology. Please do the

Brass is a metal alloy composed of different metals, primarily copper, iron, and zinc. However, the amount of copper in brass affects many of its characteristics, including brass’ color, color, strength and so on. To find out the amount of copper in brass, simple technique can be employed, called spectroscopy. Spectroscopy involves viewing the amount of electromagnetic radiation absorbed by a substance, which can let one determine the concentration of an element that composes that substance using the amount of energy absorbed. In the case of brass, this technique can then be used to find the moles of copper in bras, which can ultimately be used to out what percent of brass is composed of copper.

The element I have chosen for my element fact sheet is copper. The mass number for copper is 63,546 the atomic number for copper is 29 its in group eleven the classification is solid. copper is a transition metal. Copper's boiling point is 1,358k, melting point is 2,835k and it doesn’t have a freezing point.

An in vitro comparative evaluation of physical properties of four different types of core materials

Abstract: Many people think that going to the outer space is not that complex when talking about the materials of a rocket or space shuttle. Most people believe that metal is all that is needed and that in fact that is all it has. The truth is that it required a lot of research and procedures to come up with the right materials to people to withstand rigorous conditions. In other words, materials had to be engineered to work with extreme heat, cold and pressure changes. Due to some other issues such as collision from debris and unforeseen events the space shuttle had to be cancelled. The risks were too high even with all the engineering of materials.

The machine learning techniques that were utilized in this data analysis project were both applied to the Iris Data Set available at the UCI Machine Learning Repository (http://archive.ics.uci.edu/ml/datasets/Iris). This data was entered into a text file and saved with a .csv extension, then this .csv file was fed into the WEKA software for analysis. One of the techniques utilized was a simple visualization of the data spread, which has some predictive power in clearly demonstrating the spread of the data and thus the likelihood of obtaining the basic measurements of sepal length and width and petal length and width. The algorithm for this is simple, similar to what Excel or any basic spreadsheet can accomplish, yet is still demonstrative of machine learning in one of its simplest forms as earliest conceived (Andrieu et al, 2003). The second round of analysis conducted was a cross-validation analysis, which has more predictive power and is indicative of the stronger analytic powers available in machine learning as it forms a basic prediction of how accurate other predictions will be that is, the algorithm that is used to analyze the data also analyzes and adjusts itself in order to determine how close a fit it can come to the data (Bishop, 2006). The results of these analyses show a fairly normal distribution for sepal length and width but irregular distributions for petal length and width that would require a slightly different approach to certain modes of
