lot of energy than the rest. Also because it is a polymer it has more chains than we can count so it should have lost of energy. However the butanol could be the fuel to produce the most energy because although the paraffin is a polymer since it is harder to burn it will also take longer to burn and it might not burn within the time limit. So since butanol is the fuel with the second highest carbon atoms and the second longest carbon chains it will burn within this time and may produce the most energy

Spirit Burner Experiment Aim: To perform an experiment in the labs to determine the heats of combustion of selected alcohols and then to use this information and the gathered data from chemical data sources to determine trends in the longer chain alcohols. The Variables that MUST be controlled throughout the experiment are: • The height from spirit burner nozzle to the base of the water filled beaker • Air drafts around the room must be kept to minimum so as to keep the heat on the base of the

Molar Heat of Combustion Aim: To find the molar heat of combustion for four different alkanols: 1. Methanol 2. Ethanol 3. 1-Propanol 4. 1-Butanol - And to compare the experimental value with the theoretical. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure‚ with the final products being carbon dioxide gas and liquid water.

because there is a high amount of complete combustion and the carbon atoms are not becoming a waste product. - Ethanol burnt with a blue flame that was a more intense bright orange colour towards the top of the flame and more orange flame than methanol. - Propanol burnt a small amount of blue at the base of the flame but the majority of the flame was orange - Butanol burnt as an orange flame and little to no blue flame. This is due to the larger amounts of incomplete combustion produced

James Matthew Jocson*‚ Gianvittorio Lanta‚ Chiqui Ann Llamado‚ Jeron Manaig College of Science Department of Biology University of Santo Tomas‚ Manila‚ Philippines Abstract Five oxygen-bearing organic compounds were given namely Methanol‚ 2-propanol‚ tert - butanol‚ formalin‚ and acetone. Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas Test. This was conducted to classify the samples from

combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol for propanol‚ which has the largest molecular mass. The enthalpy of combustion
