Draw the Lewis structures for the nitrate ion. (There are three resonance structures.) Using these Lewis structures describe the bonding in the nitrate ion.

What is the geometry about all of the atoms: what is the geometry about the central N atom? What is the electron domain geometry of the oxygen atoms?

What are the hybrid orbitals on the N and O atoms in the ion?b) How many sigma bonds are in this ion?

Which orbitals overlap to form these bonds?c) Describe the pi bonding in this ion. How many electrons are involved in the delocalized system? How can you tell from the resonance forms of the Lewis structure?

Use the drop-down menus to answer each question. which runner finished the 100 m race in the least amount of time? which runner stopped running for a few seconds during the race? at what distance did anastasia overtake chloe in the race?

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
