Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was

physiological foundations of a test versus a predictive maximal oxygen uptake test. Abstract The aim of this study was to assess the validity‚ reliability and physiological underpinnings of an actual VO2max test in comparison to a predictive maximal oxygen uptake test. Eight male subjects with the following physical characteristics‚ mean and standard deviation age 19.75 ± 0.71 year; weight 72.15 ± 11.93 kg; height 1.77 ± 0.11 m performed an incremental treadmill test (53.24±7.15)‚ starting at 8

extractive metallurgy. They are: Conversion of the ore into Metal oxide or metal compound. Extraction of crude metal from metal from metal compound. Concentration of ores: Removal of the unwanted materials (e.g.‚ sand‚ clays‚ etc.) from the ore is known as concentration‚ dressing or benefaction. It involves several steps and selection of these steps depends upon the differences in physical properties of the compound of the metal present and that of the gangue. Principle: Concentration is done mainly

Elements and compounds are a result of the actions of the valence electrons. There are three types of bonds that I have learned about in the bonding comparison lab. These bonds include ionic‚ polar covalent‚ and non-polar covalent. Each of these bonds and the element compounds connected to them has individual solubility‚ conductivity‚ melting point‚ and volatility levels. The three element compounds that will follow are sodium chloride‚ sucrose‚ and p-dichlorobenzene. Sodium chloride is an ionic
