I. A double decomposition reaction takes place. |
II. Brown fumes of \[N{{O}_{2}}\]are evolved. |
III. Red residue is left behind in the test tube. |
A) I and III only
B) II and III only
C) I and II only
D) II only
Correct Answer: D
Solution :
\[\underset{White}{\mathop{2Pb{{(N{{O}_{3}})}_{2}}}}\,\xrightarrow{\Delta }\underset{\begin{smallmatrix} Lead\,oxide \\ (Yellow) \end{smallmatrix}}{\mathop{2PbO}}\,+\underset{(Brown\,fumes)}{\mathop{4N{{O}_{2(g)}}}}\,+{{O}_{2(g)}}\]You need to login to perform this action.
