Which of the following is least thermally stable?
- A \(\mathrm{MgCO}_{3}\)
- B \(\mathrm{CaCO}_{3}\)
- C \(\mathrm{SrCO}_{3}\)
- D \(\mathrm{BeCO}_{3}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{BeCO}_{3}\)
Step-by-step Solution
Detailed explanation
BeCO, is least thermally stable. The thermal stability of carbonates increases down the group i.e from Be to Ba. \(\mathrm{BeCO}_{3} < \mathrm{MgCO}_{3} < \mathrm{CaCO}_{3} < \mathrm{SrCO}_{3} < \mathrm{BaCO}_{3}\) \((523 \mathrm{K}) \quad(813 \mathrm{K})\)…
