Title: Laboratory 2: Measurement of Biochemical Oxygen Demand (BOD) Objective To determine the amount of oxygen necessary for biological oxidation of wastewater effluent and determine the amount of oxygen required by bacteria while stabilizing decomposable organic matter. Methodology Apparatus ; Biochemical Oxygen Demand (BOD) meter‚ Dissolved Oxygen bottle (DO bottle)‚ pipette‚ Teflon tape‚ dilution water‚ incubator machine. Procedure; Add 300 ml dilute water then take DO reading immediately

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are‚ by definition‚ any chemical compound containing carbon. These compounds include carbohydrates‚ polysaccharides‚ lipids‚ proteins‚ and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the

Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant

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

There are thousands of compounds which have been discovered‚ and are yet to be discovered‚ with all these possible combinations it is necessary to provide order through a systematic naming system. This naming system‚ aside from organization also provides the reader with information about the given element. There are different kinds of compounds‚ ionic‚ covalent‚ and acidic and over all of this the atoms making up the compounds are either binary or polyatomic. The simplest compounds to name are binary

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

(depending how long it was sitting in the room). The bucket was then placed in the calorimeter in a certain way. At the bottom of the bucket‚ there were 3 “dents” which were aligned with the dents at the bottom of the calorimeter jacket (#14). The oxygen combustion bomb (#15) was then opened and roughly 10 cm of the wire (metal wire provided by the instructor) was cut and attached to the arms of the cup so the pellet of choosing (which was either the Naphthalene or the Benzoic Acid) would ignite with
