i think the answer should have being D
NaNo3 would decompose to give NaNo2 and O2
Pb(NO3)2 would give NO2
The correct answer is A. Because other methods of preparing oxygen is thermal decomposition of metals such as mercury, silver, lead and reaction of sodium peroxide with water
pls the answer should be D so as to produce oxygen more conviniently ....without formation of NO2
The correct option is C...
Because decomposition of either KNO3 or NaNO3 produces oxygen in the presence of catalyst or a reducing agent...
Heating KNO3 with Ca can produce oxygen...where Ca acts as a reducing agent to facilitate the decomposition of the KNO3
