Introduction: Hurler Syndrome (MPS-I)‚ otherwise classified as Mucopolysaccharidosis‚ is the most severe form of this disease and is caused by cells being unable to break down dermatan sulfate and heparan sulfate during regular metabolism(Laberge‚ 2010). The build up of these two by-products disturbs regular cell functionality and this may cause damage within the tissues of organs (Laberge‚ 2010). Two major symptoms found within an individual with Hurler Syndrome are skeletal deformities and

Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method used to perform this lab will be to combine a metal with a solution

were copper sulfate (blue crystals)‚ sodium chloride (salt)‚ and iron. Copper sulfate is a chemical compound which is produced commercially by reacting various copper (II) compounds with sulfuric acid [1]. It generally appears as a bright blue or green crystal [1]. Its chemical formula is CuSo4. Iron is silver-white magnetic metallic and readily rusts in moist air [3]. Its chemical formula is Fe. The chemical reaction was demonstrated by the iron reacting to the copper sulfate.

Magan Agarwal Binani Cement Limited Key factors that control the compatibility between Naphthalene-based super plasticizers and ordinary Portland cements Synopsis: Super plasticizers improve the workability of concrete at low water cement ratio but this workability is sometimes lost rapidly in the first hour after contact between the cement and water. This is especially the case for naphthalene-based and melamine-based superplasticizers when used with the so called incompatible cements. It
