Which of the following is the correctly balanced equation for the reaction between NaNO3(aq) and KCl(aq)?
A
NaNO3(aq) + KCl(aq) → NaNO3(aq) + KCl(aq)
B
NaNO3(aq) + KCl(aq) → NO REACTION
C
NaNO3(aq) + KCl(aq) → NaCl(aq) + KNO3(aq)
D
NaNO3(aq) + KCl(aq) → NaCl(s) + KNO3(aq)
Verified step by step guidance
1
Identify the reactants and products in the given chemical reaction. The reactants are NaNO3(aq) and KCl(aq), and the products are NaCl(aq) and KNO3(aq).
Check the solubility of the products. NaCl is soluble in water, so it should be labeled as (aq). KNO3 is also soluble in water, so it should be labeled as (aq).
Write the balanced chemical equation using the correct states of matter for each compound: NaNO3(aq) + KCl(aq) → NaCl(aq) + KNO3(aq).
Verify that the equation is balanced by counting the number of atoms of each element on both sides of the equation. Ensure that the number of Na, K, Cl, and NO3 groups are equal on both sides.
Conclude that the correctly balanced equation is NaNO3(aq) + KCl(aq) → NaCl(aq) + KNO3(aq), as it maintains the conservation of mass and reflects the solubility of the products.
