Which of the following items is a salt?(1 point) Responses carbonic acid carbonic acid calcium carbonate calcium carbonate antacid antacid sodium hydroxide

Answer 1

Among the items listed, calcium carbonate is a salt.

To clarify:

• Carbonic acid is an acid, not a salt.
• Antacid is not a specific chemical formula but refers to a group of substances that neutralize stomach acid; some antacids may contain salts like sodium bicarbonate or magnesium hydroxide.
• Sodium hydroxide is a strong base, not a salt.

Therefore, the correct answer is calcium carbonate.
