The three minerals listed below are found in mines throughout the world. Each is a mixture of two carbonate compounds. They may be used as fire retardants because, when heated, they break down to form $\text{CO}_2$. This gas extinguishes the fire. barytocite: $\text{BaCa(CO}_3)_2$ dolomite: $\text{CaMg(CO}_3)_2$ huntite: $\text{Mg}_3\text{Ca(CO}_3)_4$ In what sequence should their effectiveness as fire retardants be ranked, from most effective to least effective?
- Adolomite, barytocite, huntite
- Bdolomite, huntite, barytocite
- Chuntite, barytocite, dolomite
- Dhuntite, dolomite, barytocite
