Experimental Design (70 points) Title | How the Volume of the Slurry Mix Effected the Biogas Generator | Type of Experiment | Experimental | Background Information | Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ the main component of natural gas‚ and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter‚ as the mixture of methane

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal.

Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the same as those of alkanes of comparable MWs. Solubility of ethers in water is comparable to that of alcohols. As chain length of ethers increases‚ solubility in water decreases. Branching of the alkyl chain results in greater solubility since London forces are weaker

Caroline Guidry Dr. Beverly A. Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

CE : Section 5 Fossil Fuels 1. 93 1(c) Alkenes can be obtained from petroleum fractions by a process called ’cracking’. Using a suitable petroleum fraction‚ a student carried out this process in the laboratory and collected the gaseous product over water. (i) What is ’cracking’ ? (ii) Draw a labelled diagram of a laboratory set-up that can be used for carrying out the process and collecting the gaseous product. (iii) An important safety precaution in the experiment is to prevent sucking

Algae Could Solve World’s Fuel Crisis Von Philip Bethge Dan Robertson is working on algae that can produce biofuel. Genetically modified blue and green algae could be the answer to the world’s fuel problems. Bioengineers have already developed algae that produce ethanol‚ oil and even diesel -- and the only things the organisms need are sunlight‚ CO2 and seawater.

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

absorption frequencies in the spectrum‚ and associate each with a specific bond (e.g. O–H‚ C=O). Keep in mind that there are usually only one or two key bands in each spectrum‚ although in some cases you might observe up to three. Do not label the alkane C–H stretch‚ since these bands are present in most organic compounds. 2. Assign a letter from the structures given (A – J). There is only one structure per spectrum. 3. Identify the main functional group present in the structure (i.e. ketone‚ alcohol

classes namely: Saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons are the simplest type of organic compounds. They are hydrocarbons in which all carbon- carbon bonds are single bonds. An example of a saturated hydrocarbon is an alkane. Unsaturated hydrocarbons are hydrocarbons that contain one or more carbon-carbon multiple bonds like double bonds‚ triple bonds‚ or both. Saturated and Unsaturated hydrocarbons have similar physical properties‚ but their chemical properties are different
