ORGANIC COMPOUNDS REVIEW SHEET 1 1. What is the most important inorganic compound? List and describe three characteristics of it. Explain why it has these characteristics. There are many important inorganic compounds that exist, but of them is much more important than the others. That compound is water. Water is the most important inorganic compound, and has three dinstinctive traits. Those are adhesion, cohesion, and capillarity. Adhesion gives water the ability to stick to different surfaces
Introduction Photosynthesis is a process done by photoautotrophs to convert inorganic compounds and light energy to organic matter. In all photosynthetic organisms, organic pigments exist to harvest the light energy. The three major classes of pigments are chlorophylls (green pigments) and carotenoids (yellow or orange pigments) which are lipophilic and associated in Chl-protein complexes as well as phycobilins that are hydrophilic. All chlorophylls (a, b, c and d) have two major absorption bands:
substances forensic scientist use to identify and compare matter, whether a material is organic or inorganic. Evidence that will be used in a court trial will depend on the examination that forensic scientist processed in the laboratory. The importance of distinguishing between organic and inorganic material is a necessary step in the criminal justice process. The differences between organic and inorganic will be explained first, next will be to explain the strengths and weaknesses of each, and finally
analysis. Quantitative analysis determines the quantity of a substance as Qualitative analysis identifies its quality. It can be considered as a branch of chemistry. One which is limited to identification of a singular or group of elements, ions, or compounds in a sample. It is, nearly, always applied when in need of performing an experiment, test, etc…since it is usually the qualitative analysis which is performed prior to the quantitative analysis (but can be performed together). The techniques or methods
CARBON Carbon, an element discovered before history itself, is one of the most abundant elements in the universe. It can be found in the sun, the stars, comets, and the atmospheres of most planets. There are close to ten million known carbon compounds, many thousands of which are vital to the basis of life itself (WWW 1). Carbon occurs in many forms in nature. One of its purest forms is diamond. Diamond is the hardest substance known on earth. Although diamonds found in nature are colorless and
incarnate.3 However, the fact that they found the structure Decker predicted did not mean that his nomenclature would be used to identify the compound. That honor was bestowed upon its discoverers Landa and Machcahcaeck who used the Greek translation of diamond, adamantane, to identify the compound.2 Crude petroleum is separated into its component compounds by fractional distillation. The procedure involves a sample of the petroleum to be heated until the sample is vaporized leaving behind any solid
body has a compound called ATP (adenosine tri-phosphate), which is an energy-containing compound. The ATP reaction releases energy in the body very quickly. This is a good thing, especially during an intense work out, when your body needs the most energy. Carbohydrates can give you energy, but it comes at a slower pace. When the muscles are using ATP for energy, a chemical process occurs where the ATP is broken down into two simpler chemicals, ADP (adenosine did-phosphate) and inorganic phosphate
in main group and transition metal inorganic and organometallic chemistry, I am confident that I could successfully teach the following courses. • All general chemistry class (chemistry for non-science majors, chemistry for science majors, honor’s general chemistry. • Inorganic chemistry –I (An introductory survey of the bonding, structure, and reactions of important metal and nonmetal compounds.) • Inorganic chemistry–II (Structure and mechanism in inorganic and organometallic chemistry, bonding
the method of homogeneous precipitation through this experiment. Introduction Thermo gravimetric analysis (TGA) is one of the common analytical thermal analysis techniques that widely use to determine the thermal profile and stability of compound. This is rather important in the industry. When the thermal profile of certain substance was know, it can be produce in large quantity by an accurate reaction with the lowest cost. With the TGA techniques, a sample of material is being heated
all except for a folded line of matter that contains the ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) of the cell. Mitochondrion make use of a process known as oxidation to make fat acids and pyruvate acid into (indirectly) ATP and Pi (inorganic phosphate). The process goes as follows: 1) Oxidation of pyruvate acid into acetyl coenzyme A. 2) Oxidation of fat acids into acetyl coenzyme A. 3) Oxidation of acetyl coenzymes from step one and two into CO2 and NADH2. 4) Oxidation
first coined the term "organic chemistry" in 1807 for the study of compounds derived from biological sources. Up through the early 19th century, naturalists and scientists observed critical differences between compounds that were derived from living things and those that were not. Chemists of the period noted that there seemed to be an essential yet inexplicable difference between the properties of the two different types of compounds. The vital force theory (sometimes called "vitalism") was therefore
Oxygen Vital to life, a necessity to combustion, and the component of innumerable compounds, oxygen is by far one of the most important elements. Astoundingly, Oxygen makes up a fifth of our atmosphere, 49.5% of all compounds on Earth contain oxygen, makes up about 2/3 of our body, yet human kind has only know of it since 1977 (http://pearl1.lanl.gov/periodic/elements/8.html). Ironically, within a period of a couple of years, three different men had stumbled upon the vital element. Carl Wilhelm Scheele
test pathway .42g 67% positive negative oxidation of secondary OH Good Things My experiment went well. I began my experiment with .64g of 2-ethyl-1,3-hexanediol. The molecular weight of this compound is 146.2g/mol. It is converted into 2-ethyl-1-hydroxyhexan-3-one. This compounds molecular weight is 144.2g/mol. This gives a theoretical yield of .63 grams. My actual yield was .42 grams. Therefore, my percent yield was 67%. This was one of my highest yields yet. I felt that this was a
The National Geographic Society “It’s right here”, was the old guard’s response when I asked him where I could find the National Geographic Society. Immediately upon entering the gates of the Shura Council Compound, I found a plaque on one of the two buildings indicating it to be the National Geographic Society. I entered the Society and began to analyze all of its aspects to determine whether or not the museum is achieving its purpose of improving the study of geography in Egypt. The National
of modern-day poetry provides – an aesthetic sense of rightness or pleasure. The vocabulary of the poem is remarkable in several ways. First of all, about one-third of the vocabulary is compound words. For the concept of “the sea” there are 50 different compounds; likewise there are 50 compounds for the concept of “a battle;” and 30 words for “king” (Chickering 5). It is truly amazing that in this poem of about 3000 lines there are 4000 vocabulary entri... ... middle of paper ... ..
discovered in the 1920's by Thomas Midgley, an organic chemist at General Motors Corporation. He was looking for inert, non- toxic, non-flammable compounds with low boiling points that could be used as refrigerants. He found what he was looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and trichloromonoflouromethane (CFC-11). In both compounds, different amounts of chlorine and fluorine are combined with methane, which is a combination of carbon and hydrogen. These two CFCs were
anything germinating. We quickly noticed something that appeared like an air bubble squirting out something green. This was our fern spore which was germinating. Next, we removed a few of the germinating spores from the petri dish and put them under a compound microscope scope. We found the spore wall and observed how the developing gametophyte had broken through the wall, as instructed by our lab manuals. One could also identify the chloroplasts with in the cell. We then put up our dishes for another
Fatal Flaws in Hamlet In the ending to Shakespeare's Hamlet, each of the main characters fatal flaws leads them inevitably to their destruction. The process of the play could not lead one anywhere else but to their ultimate fate. Claudius is basically an opportunist whose blind ambition erases his moral sense. Gertrude, through the eyes of Hamlet, is to eager to remarry her husbands brother. Hamlet himself, driven both by his need for vengeance and his inability to act was perhaps
particles. If there is a large particle with a large surface area, and many small particles, the smaller particles have a higher chance of colliding with the larger particles. However, if there are small particles, and small particles of another compound, then the reaction rate would be slower, because the particles wouldn’t collide as easily as they would with particles of a bigger size. The third factor that affects collisions is the temperature. If there is a higher temperature, then the
which one forms is based on the stability of the compound formed. The more stable the compound, the more likely it is to form. The stability of a compound with respect to its elements can be predicted by the Hf (molar heat of formation). This is the energy change when 1 mole of a compound is formed from its elements. If it is exothermic (negative), then the compound is stable with respect to its elements. If it is endothermic (positive), then the compound is unstable with respect to its elements. In
