| \[\left( N{{H}_{4}} \right)C{{r}_{2}}{{O}_{2}} \xrightarrow{\Delta }{{N}_{2}}+{{H}_{2}}O+C{{r}_{2}}{{O}_{0}}\] |
| The coefficient of \[{{\operatorname{H}}_{2}}O\]is: |
A) 1
B) 2
C) 3
D) 4
Correct Answer: D
Solution :
4 \[{{\left( N{{H}_{4}} \right)}_{2}} C{{r}_{2}}{{O}_{7}} \xrightarrow{\Delta }{{N}_{2}}+4{{H}_{2}}O+C{{r}_{2}}{{O}_{3}}\] it gives \[4{{H}_{2}}O\]when heated. Hence coefficient of Hp is 4.
