A) I and II only
B) II, III and IV only
C) I, II and III only
D) All of these
Correct Answer: D
Solution :
(i)3C\[3CuO+2N{{H}_{3}}\xrightarrow{{}}3Cu+3{{H}_{2}}O+\underline{{{N}_{2}}}\uparrow \] (ii) \[2N{{H}_{3}}+2Na\xrightarrow[300-400{{\,}^{o}}C]{Fe}2NaN{{H}_{2}}+\underline{{{H}_{2}}}\uparrow \] (iii) \[8N{{H}_{3}}+3C{{l}_{2}}\xrightarrow{{}}6N{{H}_{4}}Cl+\underline{{{N}_{2}}}\uparrow \] (iv) \[2Pb{{(N{{O}_{3}})}_{2}}\xrightarrow{\Delta }2PbO+4N{{O}_{2}}+\underline{{{O}_{2}}}\uparrow \] Therefore, all the given reactions yield elementary gases as the byproducts.You need to login to perform this action.
