A) \[1,1,2,2,1\]
B) \[2,2,1,1,1\]
C) \[2,1,1,2,1\]
D) \[2,2,1,2,1\]
Correct Answer: D
Solution :
The balanced equation is as: \[2{{K}_{2}}Cr{{O}_{4}}+2HCl\xrightarrow{{}}{{K}_{2}}C{{r}_{2}}{{O}_{7}}+2KCl+{{H}_{2}}O\]Hence, the set of numerical coefficients is 2, 2, 1.2,1.You need to login to perform this action.
