Explain the purpose of distillation in simplified terms. What is fractional distillation? Write its definition and process. What is the process used to separate petroleum into different fractions? Explain the concept of solvolysis. a) Define and explain the fractional distillation of petroleum. b) Br...
We've already seen that plastics are made from polymers, but how are polymers made? They're based on hydrocarbons (molecules built from hydrogen and carbon atoms) that we get mostly from things like petroleum, natural gas, or coal. Crude oil drilled from the land or sea is a thick ...
asome are under great pressure and they fear to fail the exams. Once the students are found cheating, the teachers should punish them severely and explain the harm of cheating to them 一些在巨大压力下,并且他们恐惧未通过检查。 一旦学生寻找欺诈,老师应该严厉地惩罚他们和解释害处欺诈对他们[translate...
What is the theory of simple distillation and fractional distillation? Describe the physical processes that occur during a simple distillation. Explain the difference between filtration and decantation. a) Define and explain the fractional distillation of petroleum. b) Briefly list the names and boiling...
This controlled explosion makes the piston push back out of the cylinder, producing the power that drives the vehicle or machine in which the engine is mounted. When the piston goes back into the cylinder, the exhaust gases are pushed out through an exhaust valve and, the process repeats ...

1. Definition of Spontaneous Combustion: - Spontaneous combustion is a phenomenon where certain combustible substances ignite and catch fire on their own without an external ignition source when they are exposed to air. 2. Understanding the Process: - This process occurs due to the heat generated ...
This research was supported by the American Chemical Society Petroleum Research Fund, and the U.S. Department of Energy through the National Nuclear Security Administration (Contract No. DE-NA0003525). This research used resources from the Advanced Light Source, which is a U.S. Department of Ene...
The proposed concepts could be used in identifying novel techniques to help reduce interfacial contamination in petroleum pipelines and other similarly affected processes. This work is also expected to lead to improved models and theories that broaden our understanding of the axial dispersion process....
The purchasing power parity is a theory of the economy that explains the determination of exchange rates. The theory states that the levels of prices between countries need to be similar. Therefore, the commodities in the two countries have the same prices ...
