Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

Background Thin Layer Chromatography: Chromatography is a sophisticated method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two phases‚ which will allow for their separation. Thin Layer Chromatography (TLC) is

Hypothesis I think that there will be a high RF value in paper chromatography‚ if we use water solvent because a solvent that has a strong interaction with a chemical will easily over come attraction from the chemical for the absorbent layer and move that chemical in a given period of time.

Logical and Physical Network Design Logical and Physical Network Design Network design is a process that begins from the first thought on how to connect to computers together in order for them to communicate and pass needed data to each other. The process may seem simple on this level and may require little consideration‚ but in fact‚ there are many areas of the network that need to be examined before the process of networking should be undertaken. For the small network‚ these considerations

Discussion: The two dyes identified were disperse blue 3 and disperse red 9. Disperse red 9 separated first because it is less polar than disperse blue 3. This is due to the structure of disperse red 9 being more symmetrical than that of disperse blue 3 and having more nonpolar bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow

1.0 Introduction There are four parts of cybercrime attack that got to be discussed in this assignment. These included Distributed Denial of Services‚ identity theft‚ social engineering and man-in-the middle attack. A topic that will be covered is type of vulnerability‚ type of attack‚ the impact of those attack and protection mechanism used to prevent attacks to happen. 2.0 Distributed Denial of Services (DDOS) 2.1 Type of Vulnerability The first vulnerability that will cause hackers to infect
