Which one of the following is an example of an acid-base reaction?
O A. CacO3 (s) – Cao (s) + O2 (g)
O B. C(s) + 02 (9) — CO2 (9)
O C. 2503 (9) ► 2002 (g) + O2 (g)
O D. HCI (aq) + NaOH (s) — NaCl (aq) + H20 (1)

Option D)

HCI (aq) + NaOH (s) — NaCl (aq) + H20 (1)

Explanation:

HCI (aq) + NaOH (s) — NaCl (aq) + H20 (1)

Acid + base → Salt + Water.

The above is a acid-base reaction in which an acid, aqeous HCl reacts completely with an appropriate amount of a base, aqueous NaOH to produce salt, aqueous NaCl and water, liquid H2O only.

During this reaction, the hydrogen ion, H+, from the HCl is neutralized by the hydroxide ion, OH-, from the NaOH to form the water molecule, H2O and salt, NaCl only.

Thus, it is also a neutralization reaction.

h let me think

the right answer is c i just did the question.
