Wang Experiment #4 Recrystallization of Pure Phthalic Acid‚ Benzoic Acid and Napthalene Introduction Recrystallization is a important method in purifying organic compounds which are solid. It is an effective method that is important to be familiar with that is essential in the industrial chemical world. This experiment will allow students to be familiarized with the technique of recrystallization by working with phtalic acid‚ benzoic acid and naphthalene from appropriate organic solvents.

Conclusion This Project has been very useful to me because I learned how to prepare cash flow statements and ratio analysis. This has improved my knowledge on financial statements which is very useful in business and commerce ever day. The work I did in this project has helped me to understand the techniques‚ applications and usefulness of financial statements to understand the performance of a particular company or enterprise without much difficulty and also understand how to prepare them in future

In this report‚ I will explain what Sulfuric Acid is‚ the health risks and hazards associated with it‚ the safety precautions that should be taken and how the spill should be handled. Sulfuric Acid‚ H2SO4‚ also commonly known as battery acid or vitriol‚ is one of the top products in the chemical industry‚ with 40 million tons produced annually in the U.S. It is a colourless‚ odourless and oily mineral acid that is soluble

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

A novel’s ending plays a very important role on the way it is perceived; for example‚ a novel could have a great plot and character development but having a dissatisfying ending will just make the reader want to toss it directly into the trash can.

the parking service were comparable for both location A (380 parking spaces) and location B (420 car parking spaces). The main difference was that there were a valet parking with 2 car parks for location A and an onsite parking for location B. Conclusion and Recommendation To conclude‚ location B---Hyyan Centre is recommended for some reasons based on the above findings. Although both locations were crowded and easily accessible with sufficient parking services‚ there was a better lease terms
