Question

Which of the following describes the decomposition of lithium carbonate (Li₂CO₃) upon heating?
Options
A It decomposes into Li₂O and CO₂.
Correct Answer
B It decomposes into LiO₂ and CO.
C It decomposes into Li and CO₂.
D It does not decompose even at very high temperatures.
Correct Answer

Option A is the correct answer.

Detailed Explanation

Page 19 states: 'Li₂CO₃is unstable. On heating, it decomposes into Li₂O and CO₂' and provides the reaction: 'Li₂CO₃ → Li₂O + CO₂'.

Hint

Recall the unique behavior of lithium compounds compared to other Group 1 elements, especially regarding thermal stability.
