Chemical vapor deposition

The first step is to put on your goggles and apron. Then you need to gather your materials. You then need to make observation of the hydrate. Observe the color, state, texture, etc. to smell the unknown substance you need to waft the substance by slowly moving the smell of the liquid to your nose. Step 2- For the lab my group changed the way we were doing the experiment for time. This is the first way that we did it for trails one to two. First you need to get a beaker and mass it on a scale…

The Tokyo Subway Sarin Attack, was considered a domestic terrorism. On March 20, 1995 Japan’s First chemical warfare attack occur. On a Monday morning, what seemed to be normal day in Kasumigaseki subway station. A disasters was about to occur. This act was caused by the members of Aum Shinrikyo, whom had 10 participants. This terrorism was considered to be religious attack. It’s mission was to take upon himself as well as others the sins the people or “world” as he called. Also he claimed that…

test tubes, test tube rack, a 3x3 optical bottom plate, two 2-mL transfer dropper, three wood splint, sandpaper, and a lighter. Caution: Hydrochloric acid are highly toxic/corrosive. Handle with care and remember to wash carefully with soap if any chemical ever come in contact with your skin. Make sure to wear goggles also while you’re in the lab. First, we filled beakers with distilled water and then brought it to our station, together with calcium metal pellets, magnesium ribbon, and…

Conclusion: The general conclusion that I was able to produce about the effects of salt on the boiling point temperature of water is that with the addition of salt, the boiling point temperature of water increases. The results of the lab experiment do agree with my predictions and I can accept my initial hypothesis. However, I believe the data would be more consistent and solid had 2M and 4M of NaCl had been included in the experiment, rather than jumping from 1M to 3M to 5M. Discussion: For…

Introduction The question that this experiment asks a lot of people is that will the water rise when you lite a certain amount of candles, and if so, how high will it rise. In this experiment, my hypothesis was that the more candles you lite, the higher the water will rise as the experiment proceeds. I know this is right because I have seen many videos about this and I have done many experiments like this one. Experimental design In this experiment you will need many different…

An enzyme is a biological catalyst; catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes also make the reaction take place more often, and are needed in small amounts; they are also neither reactants nor products. Enzymes are also proteins that are folded into complex shapes that allow molecules to fit into them. The enzymes that are involved in respiration, photosynthesis and protein synthesis work within cells whereas other enzymes are secreted…

Discovered in 1898, the element neon has helped produce a staple of American cities and everyday night life: neon lights. Neon was first proved to exist by William Ramsay and Morris Travers of London, who decided to name the newly discovered element after the Greek word neos, or new. This finding was “vital in proving the existence of isotopes” (McCormick 1). The Periodic Table of Elements shows neon on the farthest right column, meaning it belongs to the noble gas family. As a part of the…

A new, specific, rapid gas chromatography-mass spectrometry (GC-MS) method was described to identify and quantify pregabalin in human plasma. Silylation and acylation reaction were tried for derivatization of pregabalin before GC-MS analysis. Derivatization was achived using N-(tert-butyldimethylsilyl)-N-methyltrifluoroacetamide (MTBSTFA). Identification and quantification of a new derivative were performed in selected ion monitoring mode using electron impact ionization. Pregabalin was…

4. RESULT AND DISCUSSION 4.1 Introduction In this chapter, all the results and analysis in this experiment that have been performed are discussed in detailed. The analysis included characterization and optimization. In addition, the graph and table were prepared to better present the results. 4.2 Extraction Of Jatropha Curcas By Using Soxhlet Extraction Method And Microwave Extraction Method The extraction of Jatropha curcas can be done through many methods such as mechanical extraction,…

of 35.45 amu. It has a melting point of -100.98 degrees Celsius and a boing point of -34.6 degrees Celsius. However, at room temperature it is a gas. Chlorine contains 17 protons and 17 electrons and also contains 18 neutrons. The density of the chemical element Chlorine is 3.214 c/cm3. Like every member of the halogen group, chlorine has a tendency to gain one electron and become a chloride ion. Chlorine…
