A student is given two mineral samples that appear very similar. They both are opaque, white, and shiny. He knows that they are either calcite or quartz. To determine the identity of each mineral, the student puts a couple of drops of hydrochloric acid (HCl) on each sample. When calcite reacts with hydrochloric acid, carbon dioxide gas is produced. When HCl is placed on quartz, no changes are observed. Based on the information above, what evidence indicates that a chemical reaction occurs when HCl is placed on calcite?
