student example of the same procedures can help during the experiment. There are many different chemicals in O.P.I‚ or Odontorium Products Inc‚ nail polish‚ but some can be more harmful than others. The basic ingredients are Formaldehyde‚ DBP‚ and Toluene. Also‚ formaldehyde is a chemical that helps harden your nails‚ but is is also harmful as it is proven to cause lung cancer. DBP or Dibutyl Phthalate‚ makes the nail polish a little more flexible and less prone to chipping. Many companies are changing

Mini Cases in Movement Disorders Mona Dalzon Case 1 Kenny Kenny is a teenager who has experienced uncontrollable bodily and facial movements‚ various uncontrolled vocalizations‚ and other compulsions such as excessive hand washing and wringing. He has been treated with Clonidine‚ Haldol‚ pimozide and buspirone. This patient was diagnosed with Tourette’s Syndrome. Clonidine is a vasodilator that allows for blood to flow more easily to the brain. This lowers blood pressure and helps treat the tics

chemical reaction between functional groups of a diisocyanate and a Polyol. First developed in late 1930s‚ polyurethanes are some of the most versatile polymers. The diisocyanate can either be aliphatic‚ (hexamethylene diisocyanate) or aromatic like toluene diisocyanate. Examples of diols are ethylene glycol or even polyethylene glycols‚ with greater Mr. Synthetic polymers‚ like polyurethane‚ are produced by reacting monomers in a reaction vessel. In order to produce polyurethane‚ a step also known

this experiment was to separate Toluene and Hexane by distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling

What is huffing? The intentional breathing of gas or vapors with the purpose of reaching a high. What does huffing do to the brain? Changes the electrical activity of the brain. On a elecroencephalograpghy‚ (or EEG) the brain will show up as sharp impulses. What toxic effects and the "risks" that occur with this practice on the body. The brain: changes the electrical activity within the brain‚ possibly resulting in hallucinations and convulsions. Also the center of emotional behavior

sulphuric acid will act as electrophile. C5H10 + H2SO4 ==> C5H11.HSO4 For the aromatic hydrocarbon‚toluene doesn’t react with bromine water. This is because Br2 is electrophilic enough to attack double and triple bonds‚ but not electrophilic enough to attack the pi bond system of the benzene ring of toluene.For the reaction of between toluene and aqueous potassium manganate the reaction will change the toluene to benzanoic acid and the color of potassium manganate change from purple to slight purple Objective
