chemistry and physics science fair project‚ you will use the combustion of ethanol to provide energy for a small explosion. The chemical equation that describes the combustion of ethanol is shown below. (Note: Hover over the equations in this Introduction with your cursor to view enlarged formulas.) Equation 1: C2H6O+3O2→3H2O+2CO2+heat Ethanol: C2H6O Oxygen: 3O2 Water: H2O Carbon dioxide: CO2 The chemical equation states that ethanol (C2H6O)

or to provide heat to industries and homes. BIOFUELS "Biofuels" typically refer to fluid transportation fuels like ethanol‚ biogas and biodiesel that are made from biomass materials – but can include prepared solid biomass fuels. These fuels are: Often blended with the petroleum fuels - gasoline and diesel fuel‚ but they can also be used on their own. o Using ethanol or biodiesel means we don’t burn quite as much fossil fuel. Often more expensive than the fossil fuels that they

chemical known today as ethanol) in the 18th century and was extended to the class of substances so-called as "alcohols" in modern chemistry after 1850. The first alcohol (today known as ethyl alcohol) was discovered by the tenth-century Persian alchemist al-Razi. The current Arabic name for alcohol (ethanol) is “al-ġawl” – properly meaning "spirit" or "demon" – with the sense "the thing that gives the wine its headiness" (in the Qur’an sura 37 verse 47). The term “ethanol” was invented 1838‚ modeled

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate
