DRUNKEN DRIVER DETECTION SYSTEM ABSTRACT: At present drunken drivers have increased enormously and so is the deaths due to drunken drivers. The main reason for driving drunk is that the police are not able to check each and every car and even if they catch any one the police can be easily bribed. So there is a need for an effective system to check drunken drivers. In alcohol detection system the ignition of the fuel is regulated by a sensor circuit. The sensor circuit is used to detect whether

production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest in the use of renewable resources

Procedure taken from p8534‚ of Journal of Organic Chemistry vol 73‚ 2008. Thieno[3‚4-b]pyrazine-2‚3(1H‚4H)-dione (5). The following is a modification of previously reported methods. 3‚4-Diaminothiophene (2.85g‚ 25 mmol) was dissolved in 20mL of absolute ethanol. Diethyl oxalate (30mL‚ 220 mmol) was added to the solution. The reaction mixture was refluxed for 8h. After the reaction mixture cooled to room temperature‚ the solid residue was recovered by vacuum filtration. The

recreational. But‚ like everything else‚ if taken excessively‚ that is a different story. Because of that‚ many laws in different countries are made for the regulation of the consumption of the said beverages. An alcoholic beverage is a drink containing ethanol‚ commonly known as alcohol. Alcoholic beverages are divided into three general classes: beers‚ wines‚ and spirits. They are legally consumed in most countries‚ and over 100 countries have laws regulating their production‚ sale‚ and consumption.[1]

How many moles are represented by 16.0 g of ethanol‚ C2H5OH ? ❖ C = 12.011g/mol H = 1.00797g/mol O = 16.00g/mol ❖ 2C + 6H + O ❖ 46.07g/mol ❖ *16.0g/(46.07g/mol) = .35 mol 2. How many moles of NaCl are in 16.0 grams of NaCl? ❖ Na = 23.00g/mol Cl = 35.45g/mol ❖

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed
