skeleton of terpenoids may differ from strict additivity of isoprene units by the loss or shift of a fragment, generally a methyl group.3 (http://www.chem.qmul.ac.uk/iupac/class/terp.html) The purity of the oil can be determined by measuring its physical properties including optical rotation by using a polarimeter and refractive index by using a…

Name: Ifeolutembi Fashina Student Number: 13335535 Lab Partner’s Name: Ifeoma Agu Demonstrator: Maria Inorganic Chemistry Experiment 3: The Identification of Unknown Samples Objectives The experiments were carried out in order to identify 15 samples, through their physical and chemical properties. Theory A precipitation reaction is one which produces an insoluble salt as product. An example would be; Ca(NO3)2 + H2SO4 = CaSO4 + 2HNO3 The calcium salt is insoluble. Precipitation reactions…

“Chemical engineering is a branch of engineering that applies physical sciences (e.g. chemistry and physics) and life sciences (e.g. biology, microbiology and biochemistry) together with mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy (Cohen, 1996).” The field of chemical engineering is very diverse, covering areas from biotechnology to mineral processing. It would take too long to list all the products that are impacted by chemical…

occurrence. In fact, this mother of repulsive odors earns its spot on the periodic table as one of the world's 118 chemical elements, or substances that contain only one type of atom. Much like any other non-metal, it does not retain the typical physical and chemical properties of metals, such as luster. The tenth most abundant element in the universe, sulfur additionally sports a multitude of unique characteristics- some even establishing it as an essential ingredient in the production of…

Cassamajor, Kimberly P1 R1 S4 Science Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the…

IONIC LIQUIDS Introduction:- Ionic liquids are actually salts that are liquid in state, normally referred to compounds that have melting point below an arbitrary temperature i.e. 100° C. Unlike some other ordinary liquids like water and gasoline, that are composed of neutral species while ionic liquids are composed of ionic species and ionic intermediates commonly known as “ionic fluids” and “liquid electrolytes”. In ionic liquids there is a species that has a delocalized species and the other…

Discussion For the first part of the experiment, a solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a…

ii. Non-Acidic Oxygen Compounds Figure 3.4 Isomers of non-acidic oxygen compounds (Retrieved from Chemistry of Petrochemical Processes, 2nd Edition, 2001). C .Asphlathenes It is organometallic compounds and inorganic salts (metallic compounds). Mostly sodium, calcium, magnesium, aluminium, iron, vanadium, nickel are present either as inorganic salts, such as sodium and magnesium chlorides, or in the form of organometallic compounds, such as those of nickel and vanadium (as in porphyrins).…

Justin Haynes Organic Chemistry C17H20N4O6 I was given molecule 9. This molecule has the general name of Riboflavin has the chemical formula of C17H20N4O6. This can also go by two IUPAC names the first being 1-deoxy-1-(7,8-dimethyl-2,4-dioxo-3,4-dihydrobenzo[g]pteridin-10(2H)-yl)pen titol. The second name it can also go by 7,8-dimethyl-10-(2,3,4,5-tetrahydroxypentyl)benzo[g]pteridine-2,4(3H,10H)-d ione. While this molecule has the generic name of Riboflavin now .This molecule has been…

Emulsion Independent Research Project A combined effort of Timothy Chase Willard and Marcus Bortey of Mr. Cork’s Second Period chemistry class December sixteenth of 2014  Background Information An emulsion is a mixture of two or more chemicals in liquid form with no mutual solubility. Emulsions are part of two-systems of matter called colloids. Colloids are particles that cannot be seen without the use of a microscope, but are larger than the size of the individual molecules involved in the…
