EFFECTS OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile

Communist Manifesto Essay The Communist Manifesto‚ though sometimes difficult to grasp‚ was a good read. The Manifesto provided great insight on what communism is truly supposed to be. Not only did it do that but it showed the reasons why communist stand for what they do. Overall I think Marx did a good job on the Manifesto which can be seen in his clear explanations and arguments. Marx starts the book off by immediately showing that there has always been class struggle from “freeman and slave‚ lord

introduced to the concept of the “artistic manifesto”. It was something that struck me as immediately useful‚ whether for a company of artists or for a single person: a document to which you could return‚ time after time‚ to review the reasons why you started out on a particular path‚ and to examine whether those goals are still valid‚ whether you’ve remained true to them‚ and whether some of your practices need to change. My personal artistic manifesto‚ in its current iteration: I believe in art

Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in

carbonyl compounds is useful in reactions because nitriles are versatile functional groups1. Not only are they versatile functional groups but they serve as precursors in several transformations. The cyano-group is found in many bioactive molecules and plays a role in hydrogen bonding to certain biological receptors.4 Nitriles are carboxylic acid derivatives because they can easily be converted to carboxylic acid under either basic or acidic conditions. Piperonal is an aromatic compound that is present

this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons. We used the sciatic Lithobates pipiens nerve in this

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves
