Question

The total number of products formed in the following reactions:
LiNO\(_3\) \(\xrightarrow{\Delta}\) Products NaNO\(_3\) \(\xrightarrow{\Delta}\) Products Be(NO\(_3\))\(_2\) \(\xrightarrow{\Delta}\) Products

• A. 7
• B. 9
• C. 6
• D. 8

Hint:

Remember the thermal decomposition reactions of alkali metal and alkaline earth metal nitrates.

Answer 1

The Correct Option is D

1. Decomposition of LiNO\(_3\): * 4LiNO\(_3\) \(\xrightarrow{\Delta}\) 2Li\(_2\)O + 4NO\(_2\) + O\(_2\) * Products: Li\(_2\)O, NO\(_2\), O\(_2\) (3 products) 
2. Decomposition of NaNO\(_3\): * 2NaNO\(_3\) \(\xrightarrow{\Delta}\) 2NaNO\(_2\) + O\(_2\) * Products: NaNO\(_2\), O\(_2\) (2 products) 
3. Decomposition of Be(NO\(_3\))\(_2\): * 2Be(NO\(_3\))\(_2\) \(\xrightarrow{\Delta}\) 2BeO + 4NO\(_2\) + O\(_2\) * Products: BeO, NO\(_2\), O\(_2\) (3 products) 
Total number of products: * 3 (LiNO\(_3\)) + 2 (NaNO\(_3\)) + 3 (Be(NO\(_3\))\(_2\)) = 8 products 
Therefore, the total number of products formed is 8. 
Final Answer: 8.
