derivative and checking the melting points. Theory: By Using specific methods of compounds detection‚ we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identifications of the unknown ketone was accomplished using thin layer chromatography‚ melting point‚ and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components of a mixture or a specific compound from a list

| IDENTIFICATION OF SOME MACROMOLECULES | | INTRODUCTION Dehydration-synthesis is a reaction that occurs to form different types of macromolecules. It is a reaction that leaves a macromolecule structure along the lines of developing its own specific function in a living organism. The 4 most common ones are carbohydrates which includes monosaccharides and polysaccharides‚ lipids‚ proteins and nucleic acids (Mack 2012). Scientists identify different types of macromolecules to achieve

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co

Radio Frequency Identification As a major company supplying to large home improvement stores such as Home Depot‚ and Lowe’s‚ I believe that for efficiency‚ accuracy‚ availability‚ and most importantly; profit‚ we should adopt to the Radio Frequency Identification system‚ a/k/a RFID. With technology improving in our everyday live‚ we should take advantage and utilize it for our business needs. The paper and clipboard method seems to be inefficient‚ and less accurate in terms of recording and reporting

IDENTIFICATION OF THE KEY ISSUES 1. Oil piracy Approximately 1% of local production of crude palm oil‚ i.e. 0.18 million metric tonnes valued at RM325 million are lost annually to these oil pirates. The culprits involved in siphoning the crude palm oil and selling them to syndicates are tanker drivers‚ depot operators and transporters. Generally‚ 100 to 200 litres of crude palm oil are siphoned off from each tanker. The amount is replaced with liquid such as water‚ used oil or sludge which can

Abstract— This thesis will analyze several similarity measures in a dental identification context. This identification will be based on a 3D scan of a patient’s skull and 2D radiographic images taken respectively post- and ante-mortem. This approach allows to circumvent the variable projection direction and/or incorrect patient positioning when capturing the classic 2D bitewing and periapical images. Three classes of experiments can be distinguished in this paper. First‚ there are the registrations
