hose were the detailed questions on my paper. I can even send the full microsoft document. The actual question is : THE TASK You are to design an experiment to determine the enthalpy of combustion( fuel value) of the two different alcohols-Methanol and Propanol and use the data provided below to Calculate the Fuel value of each alcohol and rank the alcohols in increasing fuel value. Use 4.2Jg-1 -1oC as the specific heat capacity of water. The tables below are tables of the raw data to write out the experiment.

THE TASK
You are to design an experiment to determine the enthalpy of combustion( fuel value) of the two different alcohols-Methanol and Propanol and use the data provided below to Calculate the Fuel value of each alcohol and rank the alcohols in increasing fuel value.
Use 4.2Jg-1 -1oC as the specific heat capacity of water.
The tables below are tables of the raw data to write out the experiment. So with the tables we are supposed to be able to produce an experiment.
