Question
Chapter 5, Problem 8Q
Interpretation Introduction
Interpretation:
The dangerous hazards of carrying out distillation in a completely closed container should be explained.
Concept introduction:
The process to separate the component from liquid mixture by boiling of selective liquid followed by condensation of the mixture is called distillation. The distillation depends upon the boiling point difference of the components. The distillation is used in various industries to get the pure component.

Jet A fuel is kerosine based, consisting primarily of CnH2n+2 hydrocarbons, with n =6 to 16, so the carbon:hydrogen ratio is close to 1:2. During this flight, how much CO2 was released into the atmosphere? Assume the combustion of the fuel was complete, so all the fuel was burned to form CO2 and H2O. Give both the mass of CO2 produced (in kg and in lbs) and the volume it would occupy at 298 K, 1 atm.(b) How much CO2 would be released into the atmosphere if those passengers and crew made the trip instead, in pairs, in hybrid cars at 40 miles per gallon. Assume the density of the gasoline is 0.75 kg L-1 and that carbon and hydrogen dominate the composition in a ratio of 1:2. The road trip is 1082 miles.arrow_forwardThermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) are widely applied for the thermal analysis of food samples. (a.)
