Merseyside Company Case

However this investment would be made regardless of the project and hence only a part of the investment should be considered for the modeling purposes. What proportion of the investment would be used specifically for this project will determine the value of the Purchase Cost of Rolling Stock that would be definitely lesser than £2 Million. Currently, the model is based on the assumption that the...

Handling a Sulphuric Acid Spill

Final ChoiceI think the most effective method for handling the sulfuric acid spill is neutralisation. Sulfuric acid is a very corrosive and harmful substance which very readily forms toxic fumes that are detrimental to the health of workers and also the environment. Therefore it is vital that we convert the sulfuric acid into a form that is much less harmful. The neutralisation process is immediat...

Aldol Reaction

This is a fairly good percent yield with the fact that the experiment was performed on a microscale level. Some product may have been left in the vial or in the vacuum filter. A little loss of product due to technique makes a great difference on the percent yield since it is microscale. I had a melting point of 70 degrees Celsius to 73 degrees Celsius. This is a little low compared to the expected...

Ionic and Covalent Bonds

I concluded that sodium chloride and sodium bicarbonate contained ionic bonds because they both conducted electricity and were solid at room temperature. I concluded that oil contained covalent bonds because it did not dissolve in water, was a liquid at room temperature, and did not conduct electricity. Possible ways to improve this investigation would be to test more substances, and further exper...

Investigatory Project

Rose water, made as a byproduct of rose oil production, is widely used in Asian and Middle Eastern cuisine. In France there is much use of rose syrup, most commonly made from an extract of rose petals. In the United States, this French rose syrup is used to make rose scones and marshmallows. Perfume is a mixture of fragrant essential oils and/or aroma compounds, fixatives, and solvents used to giv...

Victoria Chemicals in Chemicals Industry

Griffin Tewitt proposes to include a renovation of the EPC Production line, costing 1 million pounds. He also believes that renovation will give the firm the lowest EPC cost base worldwide and improve cash flow by 25,000 pounds. The NPV is also stated to be at a negative figure of -750,000 pounds. Tewitt however was defensive on the negative figure, stating that the NPV ignored strategic advantage...

Titration Of Acids And Bases

The molarity of NaOH solution based on three trials was 0.1051 +/-0.0003 M. The percent KHP in substance #47 was 55.7 +/-0.3%. The significant point of this lab was to determine the end point of a reaction between an acid and a base. The data collected from the end point gave the amount of base needed to react with an acid when once wanted to perform neutralization reaction. Another significant po...

Perkin Reaction

In this experiment two compounds were successfully synthesized. The products were E and Z phenylcinnamic acids and synthesized using the Perkin reaction. However due to impurities the yield and purity of these two products was high enough. The Yield of this reaction was 60.4% and the melting point for the E product was 164-168 and Z product was 155-160. To confirm the successful synthesis of the p...

Pharmaceutical Pediatric Formulations

Mannitol is widely used as filler in several pharmaceutical formulations especially in chewable and orodispersible tablets as it has good mouth filling property. Comparing to sugars, it is comparatively less cariogenic. In some case, hypersensitivity reactions and anaphylactic reactions are reported after the intravenous infusion of 10 % or 20 % (w/v) which contain mannitol [41]. Direct action of ...

Drug Analysis

The experiment design's aim was to determine if CE-MS is effective in the determination of the components of a sample using non-volatile buffers, the sample was hair collected from drug users and analysed. The experiment was a success and the components of drugs used were separated and identified using inorganic buffers. The authors found out that using inorganic buffers were better than organic o...

This chapter will explain the previous studies related to

(Hong et al., 2018) Nitri?cation, the biological oxidation of ammonia or ammonium to nitrite followed by the oxidation of the nitrite to nitrate, plays a key role in the global nitrogen cycle linking organic matter mineralization to microbial denitri?cation and anammox in water, soil, and sediment. At present, as no appropriate method exists for direct measurement of nitri?cation rates in situ, po...

Schmidtea Mediterranea: Observations and Experiments

ОІ-catenin has been hypothesized to play an important role in head formation. To determine the effects of blocking MEK combined with ОІ-catenin inhibition, we performed a knockdown for ОІ-catenin with the aid of RNA interference and exposed planaria to PD032590. Four different groups were used in this experiment. Group 1 was injected with Milli-Q water and placed in medium, this is the overa...

Risk Assessment Involving TPH

Petroleum hydrocarbons are commonly found environmental contaminants, though they are not usually classified as hazardous waste. Many petroleum products are used in modern society, including those that are fundamental to human life (that is, fuels used in transport industry, heating and power-generating fuel). The volume of crude oil or petroleum products that is used today sideline all other chem...
