The oxidation number of the metal ion for the given coordination compound to be predicted. Concept Introduction: Lewis acid: The species which accepts the lone pair of electrons. Lewis base: The species which donates lone pair of electrons. Donor atom: The neutral molecule or the negatively charged species which donates pair of electrons is known as Donor atom. Coordinate covalent bonds: A covalent bond in which the Ligand donates both electrons to the metal ion to construct a bonding interaction known as coordinate covalent bond. To Identify: The oxidation number of the metal ion for the given coordination compound to be predicted.

Question

Comparing two means. Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash. Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1+3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161, 165, 160, 167, 166 1+3 HNO3–HCl: 159, 145, 140, 147, 143, 156 Determine whether there is a significant difference between these methods at the 95% confidence interval.

Comparison of experimental data to “known” value. Monna and co-workers used radioactive isotopes to date sediments from lakes and estuaries.21 To verify this method they analyzed a 208Po standard known to have an activity of 77.5 decays/min, obtaining the following results. 77.09, 75.37, 72.42, 76.84, 77.84, 76.69, 78.03, 74.96, 77.54, 76.09, 81.12, 75.75 Do the results differ from the expected results at the 95% confidence interval?

Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement? if the standard deviation is 0.01 and the propagated uncertainty is 0.03
