Chemistry Question on The S-Block Elements
Lithium nitrate and sodium nitrate, when heated separately, respectively, give :
A
LiNO2 and NaNO2
B
Li2O and Na2O
C
Li2O and NaNO2
D
LiNO2 and Na2O
Answer
Li2O and NaNO2
Explanation
Solution
On heating, lithium nitrate produces lithium oxide (Li2O), while sodium nitrate yields sodium nitrite.
4LiNO3→ 2Li2O + 4NO2 + O2
2NaNO3→ 2NaNO2 + O2
So, the correct option is (C): Li2O and NaNO2
