A) \[Cr{{O}_{3}}\]
B) \[C{{r}_{2}}{{O}_{7}}\]
C) \[C{{r}_{2}}{{O}_{3}}\]
D) \[Cr{{O}_{5}}\]
Correct Answer: C
Solution :
Potassium dichromate, on heating gives oxygen and chromic oxide\[(C{{r}_{2}}{{O}_{3}})\]. \[4{{K}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }4{{K}_{2}}C{{r}_{2}}{{O}_{4}}+3{{O}_{2}}+2C{{r}_{2}}{{O}_{3}}\]You need to login to perform this action.
