B)quartz
C)dolomite
D)plagioclase

Question

Quizplus · Accepted Answer

Calcite is the only carbonate mineral that readily reacts with cool, dilute hydrochloric acid to produce visible bubbles of carbon dioxide gas. Quartz is not a carbonate mineral, while dolomite and plagioclase may react with hydrochloric acid, but the reaction may not produce visible bubbles, or the reaction may be slow, depending on the concentration of the acid and the composition of the mineral.
