In a controlled experiment, acid was dropped on a sample of calcite. Which of the following results would show that a chemical reaction took place? The sample of calcite formed a puddle, showing it did not absorb any liquid. The sample of calcite formed bubbles, showing the release of a gas. The sample of calcite partially dissolved. The sample of calcite broke into smaller pieces.

`To most geologists, the term "acid test" means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as calcite.` I believe the correct answer is the second choice. `The sample of calcite formed bubbles, showing the release of a gas.`
