Carports are like the garage spaces you have in your houses. It functions the same way in giving protection to your cars. The only difference is that carports are not fixated. Instead, it is a portable and retractable device you can bring with you in your outdoor trips. The best carports for this generation are the ones made of metal, usually of aluminum or steel. There are also that has core panels made of insulated polystyrene foam. This is also wrapped with steel or aluminum. Most metal…

When it comes to towing, the B&W Tow & Stow Hitch offers different ball sizes without the need to change out the hitch anytime that you need to make a ball change. Additionally, it flips under the truck and hides out of sight when it is not in use. This hitch system is made to accommodate accessories like a draw bar for other towing needs. The draw bar makes it possible to connect other trailers that have pins or have tongues that cannot accommodate a ball. This draw bar is designed with a…

Draw resonance structures showing all the positions at which the positive charge is delocalized on the aromatic ring in the phenonium ion. If a methoxy group (-OCH3) or a nitro group (–NO2) were substituted in the 4-position on the aromatic ring, how would the stability of the phenonium ion change? Compare methoxy substituted, nitro substituted and unsubstituted, and order them by increasing stability. Explain your answer thoroughly. 2) Benzopinacol and benzopinacolone have nearly…

What can be done to protect yourself from toxic metal fumes during the welding process? It's been long known that not protecting yourself from such dangerous fumes comes at a very high price on your health. Acute and prolonged exposure may have very negative consequences. Fortunately there are many ways to protect your health and enjoy a prosperous long life. Without the proper protection, overexposure to hazardous fumes can show acute or chronic health effects. Acute effects appearing…

This article, though a few years old, gives a brief background over how oil is formed, where it is formed, and the importance of offshore drilling. The first point the articles makes is to deter from what once was believed that oil is formed from biodegrading dinosaurs to the fact oil comes from microscopic organisms at sea. Scientist estimate that each drop of sea water contain millions of life forms and after several millions of years these microorganisms get compacted deep into the…

reactions happening all the time and you don’t even know it. Some of the ways that the elements are distributed throughout the body are in the bones, blood, metabolism, genetics, and even diseases. In fact, the human body is composed of 65% Oxygen, 18% Carbon, 10% Hydrogen, 3% Nitrogen, 1.5% Calcium, and in smaller amounts of several other elements. Bones make up the skeleton of the human body. They are composed of a collagen rich mixture of calcium and phosphate, which are both elements…

is a reducing agent that is able to reduce ketones and aldehydes. In this case, camphor, which contains a ketone, was reduced with sodium borohydride. Reduction of a carbonyl with sodium borohydride occurs when the hydride ion adds to the carbonyl carbon, breaking the C=O bond and creating a new C-H bond. When the reduction occurs, the hydride transfer will occur on the less hindered side of the carbonyl group. This addition will usually create the more hindered alcohol but will generally create…

5-CinthiaV-Selenium The name of my element is Selenium. The element symbol is “Se”. Selenium was discovered in Sweden by Jons Jacob Berzelius in 1817. Selenium is an origin for a greek word meaning moon. Selenium has four energy levels. In the first energy level, it has two electrons. The second energy level has eight electrons. The third energy level has 18 electrons. The fourth energy level has six valence electrons. Selenium has forty-five neutrons. Selenium has the…

Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are…

The World witnessed a struggle for the control of oil in 1973, the decisions of which ultimately lead to globalization. As America saw the pace of life quicken in the twentieth century with the use of cars, planes, airplanes and appliances, the demand for oil to fuel this development increased. Believing that there was endless energy, the American way of life had an insatiable appetite for oil. Up until 1950 the United States had been able to supply its own energy needs, but in less than 25…
