    Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…

In the Finnsburh Episode the Danes are fighting the Frisians, and the poet says: “So they offered terms [of peace]” (1085). The “they” (hig) is indefinete and could refer to either warring party – intentional ambiguity; there is debate among scholars as to the proper referent of “they.” In line 1149 a sea-journey is…

    The capillary column is held in an oven that can be modified to build the temperature step by step (or in GC terms, sloped). This helps our partition. As the temperature expands, those compounds that have low boiling points elute from the column quicker than those that have higher boiling points. Subsequently, there are really two unmistakable isolating forces, temperature and stationary phase specified beforehand. As the mixes are isolated, they elute from the segment and enter an indicator.…
