Residential fires can kill more than 3,000 people per year in the United States. Most of these fires happen when people are sleeping and unaware of the situation. Have you ever wondered how basic items in your house protect you, such as walls, electronics, furniture, and doors? The answer lies in the material of these advantageous objects. These items contain fire-retardant materials including brominated hydrocarbons, organophosphorus compounds, and various minerals/hydrates. The question is,…

Topic: Identifying Unknown Substances. Equipments: • 5 test tubes. • 1 beaker of Acid 1 beaker of water • 4-Litmus papers • 2 Pipette bulbs. • 1 robber stopper. • 1 Bunsen burner. • Q-tips(4). • Scoopula. Observation: Which substance is which? Hypothesis: All the unknown substances that we have are soluble in water. Procedure • We had a 4 test tubes filled with small amount of white powder. We labeled each test tube. For example the first test tube was labeled as “Substance A” , the second…

there are many liposuction techniques available to breakdown and remove problem fat areas. Many of these techniques have been used since the early 1970s in Europe. Often these techniques were problematic and complications arose because they were quite invasive and caused bloodloss and significant bruising. however, since the technique has advanced, new ways of performing liposuction have made it safer and less traumatic for patients. Dr Jeffrey Klein, pioneered a unique technique known as the…

The company U.S. Sugar and Florida Crystals, together referred to as “Big Sugar”, produce raw sugar from sugar cane farming and sugar mill company. They are the only producers that produce certified organic sugar that are completely made in the USA. This company needs to be more aware of the Clean Water Act (1972) which establishes the allowable water pollutant levels emitted by US businesses. In an article, Angry About Florida's Ruined Waters, Fishermen Unite Against Big Sugar, it discusses…

Cobalt: The element Cobalt it is located on the periodic table, Group 9. Cobalt is the 27th element on our Periodic Table. It is a chemical element, it has a density of 8.9 grams per cubic centimeter. Cobalt has a boiling point of 3,100 degrees Celsius (5,600 degrees Fahrenheit). Cobalt’s symbol is Co, The atomic # is 27 so the protons and electrons are 27 as well. Cobalt has an atomic mass of 59 and 32 neutrons. The melting point is 2,719 degrees Fahrenheit. This element was discovered in…

Station 3 analyses the quality of water within Baldwin Swamp through investigating the pH Level; the turbidity; the waters dissolved oxygen, nitrites, nitrates, ammonia and temperature. The obtained results convey the pH was neutral in 2009 but is currently 5.95, the equivalent of a normal river stream or that of milk. This Ph level is great because nutrients are most available to plants in the optimum 5.5 to 7.0 range, making the difference in the pH not effective to plants. These Ph levels…

In lab, a sample of crude caffeine was purified using the technique of sublimation. Thin layer chromatography (TLC) was used to verify the caffeine's chemical structure and purity. Sublimation played a huge role in the purification of the crude caffeine. The process of sublimation is to take a chemical and change it from a solid phase directly into a vapor. Another reason as to why sublimation was used is because the caffeine can be separated from its contaminant due to the fact that it does…

, 3 visualize what organs are hidden beneath the skin of this multicellular organism and to apply this structural and functional idea of the organs to the what the human body looks like underneath the skin we live in. Out in the wild, the frogs have a very significant niche. According to Frog: Journey North ’s “Frequently Asked Questions,” the role of a frog is to “eat insects, small fish,…

I chose a business issue within my own work experience. Aircraft paint and primer contain various chemicals and materials that help protect the structure from corrosion and other high altitude and rigorous temperature exposer. But when humans are exposed to these chemicals they can become deadly. The primer used for a C-17 contains a carcinogen known as Chromium-Six. Local laws always take priority over military policy. Different agencies, including Bay Area Air, are always interested in our…

chads rise. We are using 300, 200, 100 and 60 watt lights bulbs. We are timing how long it takes for the chads to rise with each different light. Photosynthesis is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy. Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy. The input is carbon dioxide (CO2), water (H2O), minerals and light, and the…
