Question

Is this correct? Please help!

Answer 1

The answer "formation of a precipitate" it is correct.

Explanation:

In a double-displacement two reactants will exchange atoms or group of atoms between themselves to form the products. Generally we can write the reaction as following:

AB + CD → AC + BD

Of course to drive the chemical reaction to the right, one of the products have to be a precipitate.

As example we have the chemical reaction of sodium chloride (NaCl) with silver nitrate (AgNO₃):

NaCl (aq) + AgNO₃ (aq) → NaNO₃ (aq) + AgCl (s)

where:

(aq) - aqueous

(s) - solid
