Abstract Tamoxifen‚ most commonly sold under the brand name Nolvadex‚ is the most widely used drug in the treatment of breast cancer during both early and late stages. It belongs to a class of drugs known as SERMs (Selective Estrogen Receptor Modulators). SERMs work by blocking the estrogen receptors in breast cells to prevent any binding with estrogen. It is consumed orally as a tablet or as a liquid (Anon.‚ 2017). The following paper discusses the discovery of Tamoxifen‚ its laboratory synthesis

Chemical T ests for Unknowns Chemical tests have been developed as a means of identifying what functional groups are present in an unknown compound. Since IR and NMR spectroscopy has been developed‚ they are no longer critical to unknown analysis‚ but they can still be useful for confirming what you have determined by spectroscopy. Some of them look cool too! In order for a chemical reaction to work as a chemical test‚ it must 1) create a visible result (a color change‚ a precipitate‚ etc)

Making an Activity Series of Metals using different Solutions Purpose/ Hypothesis: The purpose of this lab was to clearly identify the reactivity of magnesium‚ zinc and copper. The metals reactivity will be exemplified as it will be tested with different solutions such as zinc sulfate (ZnSO4)‚ copper sulfate (CuSO4)‚ hydrochloric acid (HCL)‚ magnesium sulfate (Mg2SO4)‚ iron (II) sulfate (FeSO4) and tin (II) chloride (SnCl2). This will allow us in creating an activity series to visually see the reactivity
