Question

enter the chemical formulas of the products for the following chemical reaction.
pay attention to the phase symbols and coefficients to get the chemical formulas in the correct box.
2nacl(aq) + pb(no₃)₂(aq) → (s) + 2 (aq)

Explanation:

Step1: Predict the products

This is a double - displacement reaction. In a double - displacement reaction \(AB + CD
ightarrow AD+CB\). Here, \(A = Na^{+}\), \(B=Cl^{-}\), \(C = Pb^{2 +}\), \(D=NO_{3}^{-}\). The products will be \(PbCl_{2}\) and \(NaNO_{3}\).

Step2: Determine the solubility

According to solubility rules, most chloride salts are soluble, but \(PbCl_{2}\) is insoluble (forms a solid precipitate). Sodium nitrate (\(NaNO_{3}\)) is soluble (all nitrates are soluble and most sodium salts are soluble).

Answer:

First box: \(PbCl_{2}\)
Second box: \(NaNO_{3}\)
