Why do the minerals calcite and dolomite bubble with the mineral or its powder are placed in hydrochloric acid?A) Both minerals are sulfides, and the acid reacts to release sulfur dioxide gas.
B) Both minerals are metal hydrides, and when placed in hydrochloric acid they give off hydrogen gas.
C) The acid and the mineral together react with oxygen in the air, releasing CO2 gas.
