Question

Which of the following is formed when lithium is heated in air?

• A. Only $L{i}_{2}O$
• B. Only $L{i}_{3}N$
• C. Both $L{i}_2{O}_2$ and $L{i}_{3}N$
• D. Both $L{i}_{2}O$ and $L{i}_{3}N$

Answer 1

The correct option is D

Both $L{i}_{2}O$ and $L{i}_{3}N$

When lithium burns in air, it reacts with both nitrogen and oxygen to form $L{i}_{3}N$ and $L{i}_{2}O$ respectively.
