A) \[Cr{{O}_{3}}\]
B) \[C{{r}_{2}}{{O}_{3}}\]
C) \[Cr\]
D) \[CrO({{O}_{2}})\]
Correct Answer: B
Solution :
\[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }C{{r}_{2}}{{O}_{3}}+4{{H}_{2}}O+{{N}_{2}}\uparrow \] Hence, green coloured powder blown in the air is \[C{{r}_{2}}{{O}_{3}}\].You need to login to perform this action.
