STUDENT STUDY GUIDE FOR 8TH GRADE CHEMISTRY

Welcome to chemistry. Chemistry is the science of matter and its interactions. Everything around you is made of atoms – atoms and their chemical combinations, molecules. Everything you can see, touch, smell, and taste is made up of chemicals. So, the science of chemistry is a very wide ranging science. Parts can concentrate on how interactions of atoms and molecules allow the nerves in your body to conduct electrical signals. Other parts might concentrate on analyzing clues left by a burglar in order to help the police solve a crime. Still, other parts of chemistry might be involved in making new polymers that might be used by the fashion industry to make more colorful and longer wearing fabrics.

If you have access to a computer and the internet, there are a number of excellent tutoring sites to help students gain a better understanding of chemistry. One of the better sites for middle school students Is:

Roman Blacksmithing Research Paper

...Have you ever wondered about how blacksmithing works? Or to be more precise, how it worked in Roman times? In this essay you will learn about blacksmithing techniques, tools, and more. Let’s jump into Ancient Roman blacksmithing! You will learn about the different tools that blacksmiths would use. The tools that Roman blacksmiths used are as follow: an anvil, tongs, hammer, chisel, a poker, and a crucible. The anvil was used as a surface to hammer the soft metal from the forge into shape on. The anvil was a hard flat surface such as a rock. An anvil needed to be strong enough to not break from the blacksmith’s constant hammering. Now we move on to tongs. Tongs were used to grab things from the furnace. This was a necessary tool because...

Corrosion

...proportion to your fear of suffering. --Thomas Merton The net reaction for this first simple step is therefore: 2(Fe O2 + 2 H2O + 4 e2 Fe + O2 + 2 H2O Fe2+ + 2 e-) 4 OH2 Fe(OH)2 Iron(II) hydroxide is insoluble but its green color is almost never observed because it is ordinarily further oxidized by the oxygen: 2 Fe(OH)2 + ½ O2 + H2O → 2 Fe(OH)3 The final product (when dry) has the reddish-brown flaky character we associate with rust. Although the reaction that produces Fe(OH)2 is technically an equilibrium process (all electrochemical processes are) the value of Kc is very large (>1099 at 298 K) and left unchecked it will go to completion. But the rate is relatively slow under normal atmospheric conditions and so it is still possible to manipulate the equilibrium somewhat by changing appropriate factors. The rates of corrosion reactions--and presumably their mechanisms--vary widely. Factors which influence the progress of the net reaction in the first step of the oxidation of iron may have an effect on the overall rate. The nature of the oxide product is also very important in affecting the extent of the corrosion. For example, aluminum is a very active metal, but its oxide, Al2O3, is very dense and forms a thin protective layer on the metal which discourages further corrosion. In contrast, iron rust (hydrated forms of Fe2O3 such as reddish-brown Fe(OH)3) is typically flaky and easily crumbles off to continually expose fresh metal for reaction. Although the mechanism for corrosion...

Iron Solutions: Developing New Algal Growth Media for Increased Iron Uptake

...Iron Solutions: Developing New Algal Growth Media for Increased Iron Uptake Andrew Sweeney U.S. Department of Energy Office of Science, Science Undergraduate Laboratory Internship (SULI) University of California San Diego Lawrence Berkeley National Laboratory Berkeley, California August 6, 2015 Prepared in partial fulfillment of the requirements of the U.S. Department of Energy Office of Science, Science Undergraduate Laboratory Internship (SULI) under the direction of Dr. Nigel Quinn in the Earth Sciences Division at Lawrence Berkeley National Laboratory. ABSTRACT This study endeavored to improve sustained productivity of mass cultivated marine microalgae by using limitation of iron, a vital micronutrient, to create a growth medium that would prevent the growth of non-predatory invasive organisms. Iron’s aqueous chemistry is quite complex, and much of this study is focused on the chemical transformations of iron chelates and iron salts in the growth medium my group developed for Nannochloropsis oculata.. This algae has been identified ,because of its high proportion of unsaturated lipids, as a promising candidate for biofuels, specialty chemicals, and protein rich animal feed. Nannochloropsis oculata. also promises to be resource efficient as the cell’s small size ,and minimal agitation requirement, minimizes the loss of inorganic carbon through escaping CO2. The cells were grown in four different media (iron free, 30uM FeEDTA, 10um ferrous sulfate,...

Bio230 Final Exam Question Essay

...Iron is an essential trace element for many cellular functions. Iron uptake is accomplished with the aid of 2 proteins: • Transferrin, a soluble protein which binds to Fe • A Transferrin receptor, a transmembrane protein which binds the Transferrin/Fe complex. Using the table below, list each step in the Fe uptake process. Number each step and include a description of each step. Be sure to include the events of each step and any environmental conditions that are required or determine the action of the molecules involved. (15 pts.) Note: You must use the table below for your answers. While you do not need to use every row, YOU CAN NOT CREATE MORE ROWS. Transferrin without Fe bound does not interact with its receptor and circulates in the bloodstream until it catches an Fe ion. Once iron is bound, the iron–transferrin complex can bind to the transferrin receptor on the surface of a cell and be endocytosed. under the acidic conditions of the endosome, the transferrin releases its iron, but the transferrin remains bound to the transferrin receptor, which is recycled back to the cell surface, where it encounters the neutral pH environment of the blood. The neutral pH causes the receptor to release the transferrin into the circulation, where it can pick up another Fe ion to repeat the cycle. The iron released in the endosome, like the LDL in Figure 15–33, moves on to lysosomes, from where it is transported into the cytosol. The system allows cells to take...

Composite Materials

...parameters, the final structure is decided by cooling conditions during solidifications. The mould material has a decided effect on the structure formation. The use of end chills during casting not only favours directional solidification but also accelrates solidification. Faster cooling rates give rise to finer structures and improved mechanical properties. In this work an attempt is made to prepare Al-B4C composites cast using stainless steel and cast iron chills in a colplete adiabatic system. The microstrucutre and micro-hardness of the chill cast specimens are analyzed and reported. It is observed that the chill material has a significant influence on the microstructure and properties of the cast specimens. Finner structure and better mechanical properties were observed with the specimen cast using stainless-steel chill whereas cast iron chill gave rise to coarse structure with reduces mechanical properties. INTRODUCTION Engineering Materials There are more than 50,000 materials available to engineers for the design and manufacturing of products for various applications. These materials range from copper, cast iron, brass, which have been available for so many years, to the more recently developed advanced materials such as composites, ceramics and high-performance steels. Due to wide choice of materials, today's engineers are posed with a big challenge for the right selection of material and manufacturing processes for an application. These materials depending on...

Case Study #1

...and her hematocrit is 24% and hemoglobin is 8g/dL. 1. Describe how you would assess the patient for health practices and beliefs that are outside of the biomedical and scientific model. I would first begin by interviewing the patient. It is obvious that the patient is lacking iron, which is necessary for energy and the body’s basic functioning, and although she admits to not eating meat due to her religious beliefs, is she taking vitamins or eating other foods high in iron to compensate for her dietary choices? Although my hospital for the most part will not transfuse a patient who has an H/H of 8/24, these are borderline levels where if changes are not made, she could require serious medical interventions, including, but not limited to, a blood transfusion. Since Seventh-Day Adventists do not typically eat pork, shellfish, meat, and dairy (Jarvis, 2008), religious followers must discover other ways to get the necessary nutrients and vitamins out of food. Therefore, is she eating soybeans, fortified cereals, or taking nutritional supplements? Also, how long has the patient been following this strict diet, is it a recent change, or a lifelong practice? Has she been told that she has had an iron deficiency in the past? 2. Describe the possible impact of these practices on the care that might be indicated. From...

I worked on a job in Pryor and saw these men walking on beams and erecting this large building with steel. I was amazed and mesmerized. It was crazy to believe that these men and even women do this job. For example; they connect beams and columns, bolt-up, weld and other things. All on two inch to two foot beams. These men and women build small metal shop with red iron (softer iron) to skyscrapers with steel. There are different tasks involved to complete these projects for instance, connecting.

Ccot Research Paper

...during this time people were mainly moving to find better jobs. The industrial Revolution was the time for inventing and improving technology. A transition period to new manufacturing process. A change from hand production materials to machines and new mechanical iron production. A change from wood supply to coal. This was urbanization starting with the industrial changes and people began to move from the countryside to the city, and some moved from different countries into Britain. This began a population increase due to the urbanization in Britain. Fast developing iron, coal and textile industries were creating new work. New work meant that more workers were needed, and so more people needed a place to live. Before the Industrial Revolution the working industry were people working inside the factories and each machine was operated by hand and each machine would require more than one person to work with it. Fast developing iron, coal and textile industries were creating new work. New work meant that more workers were needed, and so more people needed a place to live. However during the transition of the Industrial Revolution the machines being produced started to only require one or two people to work the machines. Because of this many people lost their jobs. In the 1830s-1840 people began to move away from Britain. They moved to the US or different parts of the British Empire. During these years, many people suffered from low wages...

Assess the View That Economic Development Is Not Possible Without Causing Environmental Degradation – 15 Marks.

...economic development projects that are not possible without causing some environmental degradation. Construction is one of the main reasons for this, for any development to take place an area must be used efficiently to maximize space for development. A great example of this is the 3 Gorges Dam in China; this cost over $25 billion to build. Yes, it was financially positive, however a lot of land was taken, which led to huge disruptions in local ecosystems. Also china has a huge demand for Iron; this is in order to build the buildings and also for the growing demands of the car industry. Its Iron industry imports grew 34% in first four months, 2007 – feeds steel making industry. Also their steel industry is 4 x bigger than the USA, and makes 500,000,000 tonnes/year. The construction also produced large quantities of pollution which was washed downstream. With China having such a large population, it was said in 2003 13.6 in 100 people had car. Also more resources such as Oil to run the car, iron ore to make cars, rubber, wheels; oil consumption is said to of doubled in China in the last 10 years = 10% global demand. Again China is starting to overtake the USA in total oil consumption. China are said to build roughly two power stations every week, which leads to the release of large amount of carbon dioxide, a major greenhouse gas. With such rapid development means the there must be a compromise; and unfortunately this is the environment. The development of more steel mills...
