Examine the reactants of the incomplete double-displacement reaction.

2NaCl + H2SO4 → _[blank]_.

What is the product of the double-displacement reaction?

Na2SO4 + 2HCI

Explanation:

I just took a test and got it right

The products of double-displacement reaction is;

Na₂SO₄ + HCl

Explanation: The complete reaction for the double displacement reaction is;

2NaCl (aq) + H₂SO₄ (aq) → Na₂SO₄ (aq) + 2HCl (aq)

A double-displacement reaction is a reaction where cations and anions are exchanged between compounds to form new compounds. In this case, hydrogen ion combines with chloride ion to form hydrogen chloride while sodium ion combines with sulfate ion to form sodium sulfate. A single replacement reaction, on the other hand, is a reaction where a more reactive element displaces a less reactive element from its salt.
