Step 1: Define

[RxN - Balanced] 2AgNO₃ (aq) + Cu (s) → Cu(NO₃)₂ (aq) + 2Ag (s)

Step 2: Identify

Reactants: 2AgNO₃ (aq) + Cu (s)

# of O atoms: 2(O₃) = 6 O

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.

im not exactly sure but i think its b!
