A) \[{{N}_{2}}\]and\[{{H}_{2}}O\]
B) \[{{N}_{2}}O\]and \[{{H}_{2}}O\]
C) \[N{{O}_{2}}\]and\[{{H}_{2}}O\]
D) NO and \[N{{O}_{2}}\]
Correct Answer: A
Solution :
Ammonium dichromate on heating gives nitrogen, chromic oxide and water. \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }{{N}_{2}}+C{{r}_{2}}{{O}_{3}}+4{{H}_{2}}O\]
