Answer & Solution
Correct Answer
(B) i, ii only
Step-by-step Solution
Detailed explanation
\(4 \mathrm{Li} \mathrm{NO}_3 \stackrel{\Delta}{\longrightarrow} 2 \mathrm{Li}_2 \mathrm{O}+4 \mathrm{NO}_2+\mathrm{O}_2\) (anomalous behaviour) \(2 \mathrm{Ba}\left(\mathrm{NO}_3\right)_2 \stackrel{\Delta}{\longrightarrow} 2 \mathrm{BaO}+4 \mathrm{NO}_2+\mathrm{O}_2\) Thus, (i)…
