What is the type of reaction described: Aqueous lithium iodide and aqueous silver nitrate react to produce solid silver iodide and aqueous lithium nitrate. A.) Single Replacement
B.) Double Replacement
C.) Synthesis
D.) Decomposition
E.) Combustion

b)

Explanation:

The reaction being described is double displacement. This is because two diffetent compounds react to initially "switch" places with the other. In this case, iodine takes nitrates place, and lithium takes silvers place it's a way of thinking about it. This creates two completely different compounds.

B.) Double Replacement

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.
