The Evolution of the Post and Lintel Structural System The post and lintel structural system‚ more commonly known today as post and beam‚ is a construction method used to hold the weight of a building through the use of two or more upright posts that support the horizontal beam/lintel that spans between them. This technique has been used for centuries and is still seen today. When this system was first put into place it was solely for structural support‚ but as time moved forward‚ we see a shift

dehydrated by water removal. In this experiment‚ norbornene is the alkene and exo-norborneol is the alcohol product. The purpose of this procedure was to form a pure sample of exo-norborneol by reacting norbornene with an acid and excess water. Anhydrous sodium sulfate is used in order to remove water from the final product.

The electron transfer reaction between hexacyanoferrate (III) and sodium borohydride resulted in the formation of hexacyanoferrate (II) ion and dihydrogen borate ion which was strongly catalyzed by AuNPs. The redox reaction is described as BH4- + 8 [Fe (CN)6]3- + 3H2O 8 [Fe(CN)6]4- + H2 BO3- + 8H+ The advantage of hexacyanoferrate ion for this redox study is that both oxidation states of iron (+2 and +3) are quite stable with respect to dissociation and hydrolysis
