Which of the following is a correct statement?a)LiNO3on decompo...
Correct answer is C.
This is because Li shows diagonal relationship with Mg(group 2).
Which of the following is a correct statement?a)LiNO3on decompo...
Explanation:
The correct statement is option C: LiNO3 on decomposition forms Li2O while NaNO3 forms NaNO2. Let's break down the decomposition of both compounds and understand why this statement is correct.
Decomposition of LiNO3:
When LiNO3 decomposes, it breaks down into its constituent elements, lithium (Li), nitrogen (N), and oxygen (O). The balanced chemical equation for the decomposition of LiNO3 is as follows:
2 LiNO3 → Li2O + 2 NO2 + 1/2 O2
From the balanced equation, it can be seen that LiNO3 decomposes to form Li2O (lithium oxide), NO2 (nitrogen dioxide), and O2 (oxygen gas).
Decomposition of NaNO3:
When NaNO3 decomposes, it also breaks down into its constituent elements, sodium (Na), nitrogen (N), and oxygen (O). The balanced chemical equation for the decomposition of NaNO3 is as follows:
2 NaNO3 → 2 NaNO2 + 1/2 O2
From the balanced equation, it can be seen that NaNO3 decomposes to form NaNO2 (sodium nitrite) and O2 (oxygen gas).
Comparison:
Comparing the decomposition reactions of LiNO3 and NaNO3, we can observe that:
- LiNO3 forms Li2O (lithium oxide) as one of the products, while NaNO3 does not form any oxide.
- NaNO3 forms NaNO2 (sodium nitrite) as one of the products, while LiNO3 does not form any nitrite.
Therefore, option C is the correct statement because it accurately describes the decomposition products of LiNO3 and NaNO3.
