Consider the distillation of ethanol (C2H5OH) and the combustion of ethanol . Use a bullet point list to compare and contrast the 2 processes. There should be at least 5 points of comparison
Distillation
* It is a seperation process which involves evaporation and condensation a substance to get seperated from mixture.
* It is physical process
* It is an endothermic process
* Mixture of ethanol and water can be seperated by using this process where ethanol evaporates at 79 degree C where as water evaporates at 100 degree C
* The vapours collected in a container by condensation
Combustion
* It is the process of burning of substance in the presence of oxygen
* It is a chemical process. that is chemical change is occured
* It is an exothemic process. It liberates energy
* This process helps ethanol to be used as fuel
* The combustion of ethano is as follows,
C2H5OH +3 O2 ------> 2 CO2 + 3 H2O
