Identifying an Unknown Aldehyde or Ketone Introduction The purpose of this lab is to identify an unknown aldehyde or ketone substance using chemical tests. The chemical tests used in this experiment are solubility‚ Schiff‚ Bisulfite‚ and Iodoform tests. Also‚ a 2‚4-dinitrophenylhydrazone derivative synthesis reaction will be completed from which a melting point will be obtained. The chemical test results and the melting point analysis will be compared to the table of compounds given to find the

Virus vs. Bacteria Similarities – Virus vs. Harmful Bacteria Virus and Bacteria are similar. But yet they are different. Viruses and bacteria can make copies of themselves once they are inside a living organism (“J. L.”). They are both harmful bacteria and viruses. These bacteria and viruses can be helpful to the body. All diseases that people get are from virus and bacteria( Microbe Magic). Bacteria and virus are both microscopic organisms that have the same brain structure that why they are called

Explaining Bacteria Alexandra Solorzano 1E “ Hey Alex. Could you help your cousin with his homework?” “Okay‚ but I don’t understand what could be hard about fifth grade homework. Anyways‚ what are you learning about George?” “Well today my teacher started to talk about these things called Blackmeria? Or what is backferium?” “Umm I think you mean bacteria?” “Yeah! That’s it!” “Then I guess it’s your lucky day because right now in STT I’m in Cell Biology and we started to look into Bacteria too. Tell

TOMB OF THE UNKNOW SOLDIER November 7‚ 2011 1. The Unknown Soldier fought in World War I. The burial place of the unknown soldier was in France‚ near the battle at Vimy Ridge‚ marked by a tombstone that read “Known unto God”. The remains of an unidentified soldier were returned to Canada to the Tomb of the Unknown Soldier‚ a specially designed sarcophagus directly in front of the National War Memorial in Ottawa‚ the National Capital. 2. The remains of soldiers that fought

Abstract: Protecting biological diversity is defined based on analyzing the cladistic information. In this lab the null hypothesis was examined through interpreting constructed cladograms. A cladogram of five mammalian species include domestic dog (canis familiaris)‚ the Virginia opossum (Didelphis virginiana)‚ the domestic horse (Equus caballus)‚ the domestic cat (Felis cattus) and the white-tailed deer (Odocoileus virginianusis is generated based on the morphological feathers of these mammalian

To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps and tests to run to identify the unknown Gram negative organism. I

Cogswell ENG2D- 02 October 15‚ 11 Fear of the Unknown People are quick to judge‚ fear and hate the unknown. Some people may not admit it but everyone is plagued with the tendency to let our imagination take over reality and turn it into the unknown. An excellent example of this is in William Golding’s novel Lord of the Flies. All the boys in Golding’s novel are totally indulged in the theme of fear of the unknown. All of these have some “unknown” element to them; they can’t see in the dark‚ they

The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally through multiple trials for an unknown and referenced against the chemistry literature for a known compound. In Macroscale and Microscale Organic Experiments‚ 5th ed‚ Williamson notes that most pure organic solids will melt repeatedly over a narrow temperature range of 1°C. As a measure
