Lithium nitrate is industrially used as an oxidizing agent of red-colored fireworks and flares and it decomposes easily on heating. Which equation correctly represents the decomposition of lithium?Select one:a. 2Li3N → 6Li + N2b. Li3N + 3H2 → 3LiH + NH3c. LiF + HNO3 → LiNO3 + HFd. 4LiNO3 → 2Li2O + 4NO2 + O2
Question
Lithium nitrate is industrially used as an oxidizing agent of red-colored fireworks and flares and it decomposes easily on heating. Which equation correctly represents the decomposition of lithium?Select one:a. 2Li3N → 6Li + N2b. Li3N + 3H2 → 3LiH + NH3c. LiF + HNO3 → LiNO3 + HFd. 4LiNO3 → 2Li2O + 4NO2 + O2
Solution
The correct equation that represents the decomposition of lithium nitrate is:
d. 4LiNO3 → 2Li2O + 4NO2 + O2
This equation shows that when lithium nitrate (LiNO3) is heated, it decomposes into lithium oxide (Li2O), nitrogen dioxide (NO2), and oxygen (O2). This is consistent with the information given that lithium nitrate is used as an oxidizing agent and decomposes easily on heating.
