Concept explainers
(a)
Interpretation:
For a given uncharged molecule, the Lewis structure is to be completed by adding multiple bonds and/or lone pairs.
Concept introduction:
For an uncharged atom, carbon atoms will have a maximum of four covalent bonds. Nitrogen will have three bonds and one lone pair, while oxygen will have two bonds and two lone pairs. Hydrogen always contributes to one bond. The number of bond in case of halogen is one, while there will be three lone pair of electrons on halide atoms.

- 5) Confidence interval. Berglund and Wichardt investigated the quantitative determination of Cr in high-alloy steels using a potentiometric titration of Cr(VI). Before the titration, samples of the steel were dissolved in acid and the chromium oxidized to Cr(VI) using peroxydisulfate. Shown here are the results (as %w/w Cr) for the analysis of a reference steel. 16.968, 16.922, 16.840, 16.883, 16.887, 16.977, 16.857, 16.728 Calculate the mean, the standard deviation, and the 95% confidence interval about the mean.
