Discuss the nature of the bonding in the nitrate ion () no3 2 . draw the possible lewis resonance diagrams for this ion. use the vsepr theory to determine the steric number, the hybridization of the central n atom, and the geometry of the ion. show how the use of resonance structures can be avoided by introducing a de-localized p mo. what bond order is predicted by the mo model for the nuo bonds in the nitrate ion?

Which rate indicates the number of children that would be born per woman if she were to live to the end of her child bearing years

Why is it important for scientists to review and repeat the work of other scientists? 1.a scientific theory must be tested three times before it is proven. 2.the scientific method only applies to repeated experiments. 3.an experiment may have had errors that the scientists didn't recognize. 4.the results of individual scientists may be influenced by bias. 5.an experiment must be performed twice before the data can be analyzed.
