The Data Booklet may be needed for this question. A mineral was heated in a Bunsen flame until its mass no longer changed, and a colourless gas was released that made limewater go milky. After the residue had been cooled, it was added to aqueous hydrochloric acid. Vigorous effervescence occurred. Which mineral was it?
- Aaragonite, $\text{CaCO}_3$
- Bartinite, $\text{MgCO}_3\cdot\text{Mg(OH)}_2\cdot3\text{H}_2\text{O}$
- Cbarytocalcite, $\text{BaCO}_3\cdot\text{CaCO}_3$
- Ddolomite, $\text{CaCO}_3\cdot\text{MgCO}_3$
