Which mineral reacts with acid to produce bubbles of carbon dioxide gas?

• A. Halite
• B. Calcite
• C. Gypsum
• D. Quartz

Answer: (B)

Verified step by step guidance

1. Understand that the question is asking which mineral reacts with acid to produce carbon dioxide gas bubbles.
2. Recall that carbon dioxide gas (CO\_2) is produced when an acid reacts with a carbonate mineral.
3. Identify that calcite is a carbonate mineral composed primarily of calcium carbonate (CaCO\_3).
4. Know that when calcite reacts with hydrochloric acid (HCl), it produces carbon dioxide gas, water, and calcium chloride according to the reaction: \(\mathrm{CaCO\_3 + 2HCl \rightarrow CaCl\_2 + CO\_2 + H\_2O}\).
5. Recognize that halite (NaCl), gypsum (CaSO\_4 \cdot 2H\_2O), and quartz (SiO\_2) do not produce carbon dioxide gas when reacting with acid.
