Explain the process of fractional distillation to separate a solution of two liquids into pure components. Why is the gas oil fraction more viscous than the kerosene fraction? Name some (atleast six) petroleum fraction and explain what they are used for. ...
Explain what distillation is and describe the phase changes that occur during the process. a) Define and explain the fractional distillation of petroleum. b) Briefly list the names and boiling point ranges of six or more distillation fractions usually obtained from most crude petroleum. Why does ...
Growing public disapproval of plastics could prove fatal for a petroleum industry already hampered by the switch to fossil-free technologies. Ocean-Clogging Microplastics Also Pollute the Air, Study Finds by Liam Stack, The New York Times, 18 April 2019. How microplastics make an increasingly ...
Explain how soap removes oil from a fabric. Surfactants: Surfactants are compounds that decrease the surface tension of a liquid by disrupting the liquid-liquid interaction on the surface. One of the most common surfactants is detergent, which is usually used in washing clothes as it can remove ...
a) Define and explain the fractional distillation of petroleum. b) Briefly list the names and boiling point ranges of six or more distillation fractions usually obtained from most crude petroleum. Explain why beeswax is insoluble in H2O, slightly soluble in ethanol (C...
