The Real Truth about MS MS stands for Multiple Sclerosis which is a disease where the immune system eats away at the protective covering of the nerves (myelin sheath) in your body. This disease mostly affects people who are 18-60+ old‚ but can affect 3-17 year old children. Women are twice as likely to get MS than men. Liz‚ my dad’s cousin‚ raised 3 great children with her loving husband by her side when she was diagnosed with MS at the young age of 38. She died 12 years later just after she got

Lab #3 Separating Metal Cations by Paper Chromatography Introduction/Purpose: In chemistry‚ it is important to effectively analyze the components in a given mixture. In order to do so‚ chemists will analyze a mixture either qualitatively or quantitatively using different methods and equipment. Qualitative analyses are subjective‚ and only gather “non-numerical” data such as the color‚ appearance‚ and smell of the components. This data

(Friday->1:35-5:35pm) | Objective: 1 mark (What is the purpose of this experiment?) In this lab‚ spectrochemical technique was used to determine qualitively the product of a reaction. The purpose was to learn what a SN1 reaction was with combining 2‚5-dimethyl-2‚5-hexanediol and HCl and to learn how to use an infrared spectrum for analyzing the reaction. The infrared spectrum determined the alcohol content present in the final product. If the IR of a molecule with an alcohol is present‚ there will

History Multiple Sclerosis was first recognized as a specific disorder in 1873 in England. By the end of the century‚ after careful observation‚ most of the symptoms and some causes were known. In MS the immune system attacks the myelin of the bone that covers the nerve fibers. The MS can also attack nerve cell bodies which are located in the brain‚ it specifically influences the spinal cord‚ brain‚ and optic nerve. This then causes difficulties in communication between the brain and the rest
