Again, welcome to Coach Funt's chemistry blog. First, we need to setup a google account so that you can post on the blog. Once your account is setup, you can visit Coach Funt's Chemistry blog. The blog postings from last year are available, and you can look at those if you like.
For this posting, you are going to research a substance or mixture and analyze how scientists are using the substance or mixture. Pick a substance/mixture that you are interested in researching. Many substances/mixtures are used in food, cosmetics, hunting and fishing needs, medicine, etc. Answer these questions: What is the substance or mixture? What is its chemical formula? How is the substance or mixture used? Why is it used compared to a different substance/mixture? What physical and chemical properties does the substance/mixture exhibit? What physical and chemical changes can the substance/mixture go through?
The posting is due by Sunday, September 16th @ Midnight. Next Monday, we will share our postings in class. On edline, the rubric for the blog postings is available under the "contents". The blog will count as a quiz grade.
If you have any questions, please let me know. Have Fun!

ReplyDeleteLuminol Chemiluminescence Reaction
ReplyDeleteThis luminol reaction is what makes the light sticks, which criminalists use to detect traces of blood at a crime scene, glow. Luminol powder (C8H7O3N3O2) is mixed with hydrogen peroxide (H2O2) and a hydroxide (e.g., KOH). A small amount of the solution is put where the blood may be found, and if there is any blood then the solution will glow blue. It glows for about thirty seconds, which is just enough time to take the pictures they need. The iron that is in the blood acts as a catalyst for the reaction which causes the luminol to glow. Scientists use this solution because they do not have to use very much of it, and it does not destroy DNA. A physical property of this solution is when the clear substance and powder change into a glowing blue solution. A chemical property is when the iron reacts with the luminol to make it glow. The chemical change is when luminol powder, hydrogen peroxide, and hydroxide are mixed to form chemiluminescence. The physical change is when the luminol powder changes into a liquid after being mixed.

water pollution is a big problem in America and around the world, but a team at northwestern university has developed nano technology that may be able to separate water molecules from molecules containing metals such as mercury and cadmium. The nano molecules can separate the contaminants because they can capture heavy metal molecules in their hair-like texture. scientist are developing sheets of film made of this new substance that can be placed in rivers,lakes, etc. to clean the water.

everybody knows what a battery is and that they are used to power electrical objects. Not everybody knows how they are powered though. Some of the knew batteries that are being used have lithuim (L) in them which is the third element on the periodic table. These batteries are the best because they are small, hold a long charge, and are cheap, unfortunately there is one problem with the lithuim batteries though. They can burst into flames sometimes. The reason for this is if the battery gets hot enough to ignite the electrolyte then the electronical devise will burst into flames. So there are good and bad reasons to use the lithium batteries and there is a pretty good reason not to but fortunately the lithuim battery does not explode often.

Kaolin, which is Al2Si2O5(OH)4 or hydrated aluminum Silicate, is a white, fine particle, non-toxic substance that’s very versatile in its uses, including paper, rubber tires, fertilizers, pesticides, and herbicides, paint and is a raw material in white cement. Kaolin is used compared to other elements for these uses because of its high particle and flat plated characteristics, and because it is non-toxic, as previously mentioned. Kaolin was formed along Georgia’s fault line over 50 million years ago by the erosion of crystallized rock and the Kaolin mining industry has a very large effect on Georgia’s economy. Kaolin is interesting to be me because it is mined in Georgia and for its many uses.

Talc is used in many ways. The chemical formula for talc is Mg3(Si4O10)(OH)2. It is soft, white, odorless, and its density is about 2.75g cm3. Talc has a low reactivity, not flammable, and it does not react to air or water. It is used in powder, chewing gum, boiled sweets, wastewater treatments, and cosmetic products. It is used in the paper making process to absorb sticky particles. It reduces the viscosity while making rubber. Talc particles also make the bacteria heavier and accelerates their sedimentation in wastewater treatments. I did not realize talc was used in so many ways.

Sodium is a soft metal, reactive and with a low melting point.From the commercial point of view, sodium is the most important of all the alkaline metals.Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen. Sodium is a compound of many foodstuffs, for instance of common salt. It is necessary for humans to maintain the balance of the physical fluids system. Sodium is also required for nerve and muscle functioning. Too much sodium can damage our kidneys and increases the chances of high blood pressure.
ReplyDeleteThe amount of sodium a person consumes each day varies from individual to individual and from culture to culture; some people get as little as 2 g/day, some as much as 20 grams. Sodium is essential, but controversely surrounds the amount required.
Contact of sodium with water, including perspiration causes the formation of sodium hydroxide fumes, which are highly irritating to skin, eyes, nose and throat. This may cause sneezing and coughing. Very severe exposures may result in difficult breathing, coughing and chemical bronchitis. Contact to the skin may cause itching, tingling, thermal and caustic burns and permanent damage. Contact with eyes may result in permanent damage and loss of sight.

Lanolin is a chemical substance made up of Carbon, Hydrogen, Nitrogen, and Oxygen. (C4H7NO4) Lanolin is used in many things,such as, chap stick, lotion, shaving cream, skin cosmetics, and mostly soap. Lanolin is obtained from the wax found on sheep's wool. Lanolin is a fatty-like substance with a yellow color and can be confused with petroleum jelly because of the similar physical characteristics. Olive oil can be a substitute for Lanolin. Lanolin is able to go through crystallization and it has a low melting point.

Mercury is a very important Element. Because we use it in barometers and thermometers which we use everyday to measure temperature for fevers and such. Mercury is the only metal that is liquid at room temperature. But it also has a very high density. because it has a very high density Americans used to use it as an amalgam which was in tooth fillings, but it was phased out because of safety precautions. The amalgams are made of 70% silver and 30% tin when mixed with mercury. The amalgam would expand when inserted inside your mouth to form the fillings. I got my information from:

Uranium(U) is a dense, hard, and radioactive metal. Uranium's density is 18.95 g.cm-3 at 20°C. Uranium's main use is for nuclear energy (when radioactive). When Uranium is no longer radioactive it can be used for bullets, missiles, and protective shells for tanks. To create nuclear energy Uranium must go through fisson, which is the process of spitting an atom. Uranium's chemical formula varies depending on the material it is combined with. Compared to other elements that can be used for energy, Uranium is a very hazardous material that can cause terrifing effects if not handled properly. Physical properties of Uranium include its heavy weight, density, its melting point at 1132 degrees Celcius,boiling point at 3818 degrees Celcius, and metallic color. Chemical properties include its radioactivity and its ability to combine with nonmetal substances/elements. Uranium can go through fission and create energy, and it can react with many other substances which changes Uranium's original state. I personnally like this element because it can contain a lot of energy in a small amount. Overall, Uranium is a not a widely used element, but it has many uses.

Clycosarin is a deadly toxin used in chemical warfare with a chemical makeup of C7H14FO2 and an atomic weight of 180.14. It's original purpose was to replace standard mustard gas as a viable chemical weapon after World War II. Although many of the exact physical and chemical properties are classified by the U.S Government, cyclosarin is known to be in a gaseous state at room temperature but can also be in the form of a liquid. Cyclosarin has a strong odor and if inhaled directly it can cause a shut down of the nervous system and in extreme exposure, death. Cyclosarin was the chemical weapon allied troops feared Saddam Hussein would use on the coalition during the First Gulf War. It was outlawed during the Cold War when the United States and the Soviet Union signed the first SALT Treaty and agreed to dismantle and stop researching their chemical weapons capabilities.

Boron is a mineral that is found in foods and the environment. People take boron supplements as medicine. Boron is used for building strong bones, treating osteoarthritis, as an aid for building muscles and increasing testosterone levels, and for improving thinking skills and muscle coordination. Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Boron is concentrated on Earth by the water solubility of its more common naturally occuring compounds, the Borate minerals. Boron is yellow-brown non metallic crystal substance and has a electrochemical equivalent of 0.1344/amp-hr.

The chemical im doing is Neon. It is the tenth element on the periodic table and its symbol is Ne. The element has no color, and is a nearly inert noble gas. Neon gives a distinct reddish glow when used in vacuum discharge tubes and neon lamps and is found in air in trace amounts. Neon is the second-lightest noble gas.
ReplyDeleteIt glows reddish-orange in a vacuum discharge tube and has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen. Neon has the most intense discharge at normal voltages and currents of all the rare gases. It is used for lighting up signs and is also used in long tubular strips in car modification.
The ions, Ne+, (NeAr)+, (NeH)+, and (HeNe+), have been observed from optical and mass spectrometric research. In addition, neon forms an unstable hydrate. This gas is similar to exnon.
This gas is used for a number of things. One of its main uses is for signs. When neon is being put into the signs it is very hot and as it burns in the signs it is still hot.

im doing the fuel diesel carbons found in diesel ar hydrocarbons saturateded and armatic sulfur and many others. Diesel is used because it puts off more power than gasoline while useing less fuel. Thus it is used in machinery and large trucks and trains. but there three diffrent types of diesel regular diesel, b20 diesel,and e85diesel. B20 stands for 20 percent biodeisel and 80 percent regular diesel. Biodeisel is made from soybeans instead of crude oil. Biodeisel is better for the enverment than regular deisel.

Clorine, or Cl, has an atomic weight of 35.4527. As a molecule it is C12. It is a member of the halogen group of elements and combines with almost all of the other elements. Clorine as a green or yellow-ish gas can act a respritory irritant while liquid clorine acts corrosive and could severely burn the skin. It also has a strong smell and could easily be deadly if inhaled. Clorine can be used to disinfect drinking water. It also is used in textiles, paper products, dyes, paints, insecticides, disinfectants, and many other products. The element is used to manufacture chlorates, carbon tetrachloride, chloroform, and in the extraction of bromine. Chlorine has also been used as a chemical warfare agent. I chose clorine because it was interesting that it could be used in so many different ways.

Many attractants, scents, and minerals are used to bring in animals such as deer. But what makes these have to have products so effective? Deer love sweet stuff. Such as peanut butter and sugar beats. Why not mix the two with something? Most hunters who can bait there deer in use corn. In overpopulated areas, corn can be uneffective and avoided by deer. Who would have thought peanut butter would be a solution? Peanut butter has molasses, which triggers a deers scent glands from miles away. Peanuts theirselves are packed with protein for deer . The two together are a deadly combination. One mixture that is so pungent to smell, yet tasty to deer is crab apples. But, there's a twist. Cut the apples up and boil them with molasses. This will draw deer in from great distances.

DeleteMethylenedioxypyrovalerone is a mixture of man made substances and being marketed as bath salts. This compound has some of the same effects as marijuana; however, it does not contain any plant life. People have used this drug by injecting, eating, and snorting. The side effects of the drugs include: paranoia, seizures, and hallucinations. Georgia law does not include all of the possible chemical formulas for this drug. Drug manufactures are constantly changing the chemical make-up of the drugs to avoid prosecution. The Georgia Board of Pharmacy has recently adopted several emergency rules that give law enforcement officers the authority to seize these drugs. The latest versions of the chemical can be found in the latest rule posted on the board's website: sos.ga.gov/plb/pharmacy.

Potassium, K, is a soft, silvery-white alkali metal. The atomic weight of potassium is 39.0983 and it is placed 19th on the periodic table. The melting point of potassium is 63 degrees Celsius (145 degrees Fahrenheit) and the boiling point is 770 degrees Celsius (1420 degrees Fahrenheit). Potassium is a very small element, with a density less than that of water, which means that it can float on water. Putting potassium metal on the surface of water is a bad idea though, because the potassium would give off hydrogen gas, causing the potassium to skip along the surface of the water. Eventually the potassium would catch fire, and potentially explode. Potassium is sometimes used as a heat exchange medium. A heat exchange medium is a material that picks up heat in one place and transfers it to another. Potassium metal is sometimes used as a medium in nuclear power plants. Potassium is also essential to human beings and plants. Plants require relatively large amounts of this element in order to grow and remain healthy. It is also used in the digestion of food in humans and in the proper function of the eyes.

Concrete is a common mixture. It is made up of cement, sand, and gravel. It is used mainly in building houses.Concrete must have a low-level of permeability to avoid moisture and retain chemical and volume stability. There is no set chemical formula for concrete because the amount of the mixture won't always be the same. Concrete isn't flammable and doesnt have any chemical changes. It can be broken though which will change the physical property of it.
