Question

What will be the products on heating Barium Nitrate Ba(NO\(_3\))\(_2\)?

• A. BaO, NO\(_2\), O\(_2\)
• B. Ba, NO\(_2\), O\(_2\)
• C. Ba(NO\(_2\))\(_2\), O\(_2\)
• D. BaO, N\(_2\)O

Hint:

Group 2 metal nitrates decompose on heating to give metal oxides, nitrogen dioxide (NO\(_2\)), and oxygen (O\(_2\)). This is a common trend used in thermal decomposition problems.

Answer 1

The Correct Option is A

Barium nitrate, a group 2 metal nitrate, decomposes upon heating, yielding the corresponding metal oxide, nitrogen dioxide, and oxygen gas.
The general decomposition reaction for group 2 metal nitrates (e.g., Ba(NO\(_3\))\(_2\)) is: \[\n 2Ba(NO_3)_2 \xrightarrow{\Delta} 2BaO + 4NO_2 + O_2\n \] Products Explained:
BaO: The metal oxide, a product of the nitrate's decomposition.
NO\(_2\): A toxic brown gas, formed from the breakdown of the nitrate ion.
O\(_2\): Oxygen, released during the decomposition. Consequently, heating barium nitrate produces: \[\n \boxed{\text{BaO, NO}_2, \text{O}_2}\n \]
