Answer:
A.) AgCl
Step-by-step explanation:
In double-displacement reactions, the cation of one compound is swapped with the cation of another.
These are ionic compounds made up of one cation and one anion. In this reaction, Ag⁺ and Na⁺ are the cations and NO₃⁻ and Cl⁻ are the anions. Since all the ions either have a +1 or -1 charge, the charges balance perfectly (no subscripts need to be added).
As such, the possible products of this reaction are AgCl and NaNO₃.
