Directions: Respond to each statement on the lines provided. 5. Determine how an electron dot diagram provides information on the number of
bonds an atom of a certain element can form.
6. Write an example of two types of atoms that are likely candidates to form a chemical
bond.
7. Draw an electron dot diagram for fluorine (F), which has seven valence electrons.
8. Explain why some elements, such as the noble gases, are stable and do not react
with other atoms, but the atoms of other elements are unstable and form chemical
bonds easily

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?

What will most likely happen when two bromine atoms bond together?
