Introduction Analytical chemistry considers and employs a variety of equipment and methods in order to separate, identify and quantify matter. After the first flame tests in 1860, the importance of qualitative and quantitative analysis has been identified and major advancements have been made with many of the spectroscopic and spectrometric methods only being refined in the late 20th century. One of these methods includes the analytical technique ‘mass spectrometry’. Mass spectrometry assesses the mass-to-charge ratio of ions. Since mass spectrometry...

Abstract The elements of a crime are complex. Criminologists still argue whether the dominating cause is sociological, psychological, or something else. Additional blockade to progress is the fact that criminal violence is not a single status, but rather a diverse set of afflictions. The study controlled for a host of possible intervening factors, including gender, diet, illicit drug use, psychiatric medications, the season of the year, dietary processor of serotonin, alcohol and tobacco use, body mass, socioeconomic status, IQ, and...

Abstract For our project we made cookies and found out why certain ingredients affect the cookies and how they affected it. We used a basic recipe for cookies and took out one ingredient at a time flour first, then unsalted butter ,then baking soda , and lastly eggs we found out that the flour makes it a dough, the butter makes it thinner and crispier, the eggs make it fluffier, and the baking soda causes a reaction twice to make...

Nowadays, many people are interested in whether chemistry should be taught at public in school. Because some people did not like to study chemistry, and school did not have enough money for students to learn it，therefore they think school should cancel chemistry classes. However, it is necessary for students to study chemistry. To begin with, chemistry explain the nature world. Furthermore, it prepares for people to get better jobs. Moreover, learning chemistry is result in better informed citizens of nature...

Abstract Chemical weapons are specialized weapons to inflict death or harm on humans. For example, blister agents will burn a person’s mucous membranes, skin and eyes. Chemical weapons were used during war as it is deadly and stealthy. During world war 1,there was a colorless chemical weapon that makes the soldiers did not noticed that they have received a fatal dose. The chemical weapons have high potential to be used not only in war but in daily life as protection...

The chemical building block (CBB) is a molecule which can be converted to various secondary chemicals and intermediates, and, in turn, into a broad range of different downstream uses. The organic building blocks assembly is an effective strategy to synthesize materials. Simple molecule structures such as tetrafluoroethylene (ETFE) is an universal and magical monomer that are widely used in the construction of high polymer materials and nonlinear optics materials. The simplicity of manufacture greatly promote their application in material industry...

Chemistry deals with the conversion of substances into new substances through the formation and breakage of chemical bond. This conversion may happen at different speed. Some reaction happens instantaneously whereas some takes millions of years to happen. Reaction rates are of great importance. The feasibility of a chemical reaction particularly a commercial chemical process often depends on the reaction rate if the process is too slow it may not be suitable for commercial exploitation. It also relates, for example, what...
