Consider the reaction between 15.0 mL of a 1.00 M aqueous solution of AgNO₃ and 10.0 mL of a 1.00 M aqueous solution of KBr. When these react, a precipitate is observed. What is present in solution after the reaction is complete? Note: the solid is not considered to be in solution

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
