Multiple Choice

Which of the following is the balanced equation for the reaction between NaNO3(aq) and KCl(aq)?

NaNO3(aq) + KCl(aq) → NaK(aq) + ClNO3(aq)

NaNO3(aq) + KCl(aq) → NaCl(aq) + KNO3(aq)

NaNO3(aq) + KCl(aq) → NaKCl(aq) + NO3(aq)

NaNO3(aq) + KCl(aq) → NOREACTION

Verified step by step guidance

Identify the reactants and products in the given chemical reaction. The reactants are NaNO3(aq) and KCl(aq).

Consider the possible products of the reaction. In a typical double displacement reaction, the cations and anions switch partners. Therefore, the products would be NaCl(aq) and KNO3(aq).

Write the balanced chemical equation for the reaction. Ensure that the number of atoms for each element is the same on both sides of the equation. The balanced equation is:

{Na NO 3}_{(aq)} + {K Cl}_{(aq)} \to {Na Cl}_{(aq)} + {K NO 3}_{(aq)}

Verify that the equation is balanced by counting the number of atoms of each element on both sides of the equation. Sodium (Na), nitrate (NO3), potassium (K), and chloride (Cl) should all be balanced.

Understand that the other options provided are incorrect because they either suggest impossible products or no reaction. The correct balanced equation reflects the typical behavior of a double displacement reaction.
