In KCl, how are the valence electrons distributed? Question 14 options:

A)

The electrons are unequally shared between K and Cl, forming a polar covalent bond.

B)

The electrons are equally shared between K and Cl, forming a covalent bond.

C)

The electrons are shared between many K and Cl ions, creating a "sea of electrons."

D)

The electrons are transferred from K to Cl.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
