Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

Waves

Words: 386 (2 pages)

Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves are waves of…

Soil

Words: 1160 (5 pages)

Discussion The process of consolidation is often confused with the process of compaction. Compaction increases the density of an unsaturated soil by reducing the volume of air in the voids. Meanwhile, Consolidation is a time-related process of increasing the density of saturated soil by draining some of the water out of the voids. According to…

Frequently Asked Questions about Chemical Engineering

Don't hesitate to contact us. We are ready to help you 24/7

What is chemical engineering exactly?
Chemical engineers develop and design chemical manufacturing processes. Chemical engineers apply the principles of chemistry, biology, physics, and math to solve problems that involve the production or use of chemicals, fuel, drugs, food, and many other products.
Why did you decide to become a chemical engineer?
Chemical engineers work to improve the quality of people's lives. ... Chemical engineers are helping to end starvation, disease and poverty. They are working to save the environment by developing alternative technologies to combat acid rain, lead pollution and the greenhouse effect.
Why is chemical engineering important?
Most items used by people everyday have needed chemical engineers to produce them. Chemical engineers are helping to end starvation, disease and poverty. They are working to save the environment by developing alternative technologies to combat acid rain, lead pollution and the greenhouse effect.
Why is chemical engineering the hardest?
Since a chemical distillation is less tangible and visual than say a mechanical system of gears transferring energy from source to destination, applying advanced math and science concepts becomes more difficult to comprehend.
