certain industries are exposed to carcinogens during their jobs. The amount and duration of these carcinogens can affect a worker’s health and possibly cause them cancer. The most common chemicals that are found in workplaces are asbestos‚ lead‚ benzene‚ and vinyl chloride. The longer they endure these dangerous chemicals‚ the more likely their cells are to become damaged.The United States have created regulations in the workplace to limit the amount of exposure to workers. Outside of the workplace

11. Account for the fact that ethylene glycol (HOCH2CH2OH) is less viscous than glycerine (HOCH2CHOHCH2OH)‚ but more viscous than ethyl alcohol (CH3CH2OH). 20. Consider the following substances: sodium fl uoride (NaF)‚ chlorine monofl uoride (ClF)‚ hydrogen fl uoride (HF)‚ and fluorine (F2 ). (a) What type of particles does each substance have? (b) What type of intermolecular attractive forces hold the particles together in each substance? The table below lists the melting point (mp)‚

ring and gives a coloured salt compound. When Nitric acid is heated with a protein like tyrosine it gives off a yellow colour ‚or tryptophan and orange colour this is down to nitration. This is why this test is used for the presence of an activated benzene ring. The “(4) Test for sulphur”this

known as aspirin as well as methyl salicylate‚ which is a component of oil of wintergreen. Both of which are used for pain relief/soreness. Salicylic acid is a member of the phenol class as their hydroxyl group (OH) is attached to a phenyl ring (benzene) and many phenols react with ferric chloride to cause a colour change. And so‚ in this investigation we are to prepare the two esters and compare their reactions with ferric chloride compared to the reaction between salicylic acid and the ferric chloride

Experimental Procedure and Interpretation of Data Collection and Preparation of Materials The bark of Santol (Sandoricum koetjape (Burm.f.) merr.) were collected at the researchers backyard on Rosales‚ Province of Pangasinan. The collection was done in the month of August to September 1999. The bark was collected through the used of a knife. The bark were dried under the sun. And were placed into container and tightly closed ready for expression. Preliminary Test for the Determination of Plant

bending was found around 750 cm-1. The bending fits in its range‚ which is generally between 1000 and 650 cm-1. The last few peaks that were inspected were found around 1600 cm-1. This signifies a carbon having a pi bond with another carbon in a benzene ring. Therefore‚ this rules out all the alkanes and just leaves the phenyl hydrocarbon
