I am going to investigate the enthalpy change of combustion for the alcohol homologous series. I will investigate how alcohols with increasing number of carbons affect the enthalpy change when an alcohol goes under combustion. The energy that alcohols release when being used is called the enthalpy change of combustion. This is defined as "Standard enthalpy change of combustion‚ is the enthalpy change when one mole of a substance burns completely in oxygen under standard conditions (298K‚ 100 KPa

the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the experiment: * Butanol (C4H10O) * Ethanol (C2H5OH) * Propanol (CH3CH2CH2OH) * Methanol (CH3OH) * Pentanol (C5H11OH) Costs; they’re always a problem or a benefit. And when they are a problem‚ they must be dealt with accordingly. Fuel is a common problem associated with money‚

A student is given two alcohols with which to perform Lucas Test. These are cyclohexanol and 2-methyl-2-propanol. The bottles containing each alcohol are labelled‚ but the propettes used are not. The student accidentally muddles the propettes. When drops of each alcohol are mixed with Lucas. Reagent and kept at 27 °C‚ both solutions become turbid. How can the

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

Fuels Investigation Aim: To find out which fuel gives out the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific

Introduction The VSEPR Theory for this experiment stated that electron group repels against each other and they occupy a lot of space. Scientists use VSEPR Theory to determine the molecule’s geometry by counting the number of electron domains that surround the central atom. Electron domain can be described as a lone pair‚ single‚ double and triple bond‚ and also even free radical. Lone pairs tend to occupy a lot of space and lower the angle of a bond‚ which gives molecular geometry. Lewis

Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen
