Combustion Of Alcohols Planning This investigation involves burning alcohol in the air. Key science- Chemistry by Eileen Ramsden says that " an alcohol is a series of organic‚ homologous compounds‚ with the general formula Cn H2n+1OH". The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide: Cn H2n+1OH +(n+n/2)-1O2 ? nH2O + nCO2 The structure of the molecules in this reaction is: H H | | H - C - C - O- H + 3[O=O] ? 1/2[O=C=O] + 3[H-O-H] | | H H This reaction

for two types of fuels (methanol and ethanol) unlike the professional report which showed results for many types of fuels including biogas‚ LPG‚ kerosene and wood. This might mean that the reports would not be able to be compared as easily making them less useful. The professional report would be more useful for general fuel efficiency as it is more detailed whereas mine would be more useful if only information about the efficiency of methanol and ethanol was needed. Both of the reports

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air to sustain the chemical reaction‚ they can however produce electricity continually for as long as these inputs are supplied

The first thing that we do was mixing the thiourea and anhydrous methanol we dissolved the compound and put on the hot to warmed add a few drops of carbon tetra chloride-octanol when you see that the crystals filter it. After this things put it inside the oven and left it to an hour after an hour we weigh it again and solved for the percentage recovery.

Preparation of the propolis extracts: the propolis sample of the Brazilian native bee species Melipona quadrifasciata was obtained in May‚ 2013 in the city of Blumenau‚ SC‚ Brazil (26 ° 54’21.3 "S 49 ° 04’49.1 "W). In order to obtain a hydroalcoholic crude extract (HCE)‚ 284.3 grams of propolis were pulverized and macerated in 70% ethanol (m m-1)‚ left in a dark chamber for 7 days at room temperature‚ filtered in vacuum and taken to complete drying in a rotary evaporator with reduced pressure.

Production of Biodiesel by Enzymatic Transesterification: using Waste Cooking Oil as feedstock and Candida Antarctica Lipase B as Biocatalyst. CHAPTER 1 INTRODUCTON The high cost of bio-diesel‚ compared to petroleum-based diesel‚ is a major barrier to its commercialization. It has been reported that 60-90% of bio-diesel cost arises from the cost of the feedstock oil (C.C. Lai et al.‚ 2005). Studies showed the potential of waste-cooking oil (WCO) as a material for biodiesel production
