Its chief components are Carvacrol‚ Thymol‚ Cymene‚ Caryophyllene‚ Pinene‚ Bisabolene‚ Linalool‚ Borneol‚ Geranyl Acetate‚ Linalyl Acetate and Terpinene. The application of oregano had grown and is still expanding worldwide because of the advancement in science and technology that maximized and specified the capabilities of this plant.

Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

component of vinegar (apart from water; vinegar is roughly 8% acetic acid by volume)‚ and has a distinctive sour taste and pungent smell. Besides its production as household vinegar‚ it is mainly produced as a precursor to polyvinylacetate and cellulose acetate. Although it is classified as a weak acid‚ concentrated acetic acid is

Solvents used were water‚ methanol‚ n-butanol‚ ethylene glycol‚ acetone‚ hexane‚ toluene‚ ethyl acetate‚ and dichloromethane. Then added to the vials was 0.5 mL of isooctane in each one. The vials were then swirled and observed to determine solubility. In part two of the experiment‚ 0.5 mL of concentrated sulfuric acid was added into two sample vials

7. Modelling Polyethylene As mentioned previously‚ PE is one of the most important polymers in the world. ADMET has been used to systematically model commercially relevant polymers‚ specifically PE and copolymers of ethylene and another monomer. ADMET is capable of producing PE with specific sequences of monomer units‚ as well as random copolymers via copolymerization with 1‚9-decadiene. The ability to precisely synthesize these polymers has opened the door to exploring the molecular origins of

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid.

If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are
