B) 2, 2, 1, 1, 1
C) 2, 1, 1, 2, 1
D) 2, 2, 1, 2, 1
E) 2, 2, 2, 1, 1
Correct Answer: D
Solution :
This equation can be balanced as: \[2{{K}_{2}}Cr{{O}_{4}}+2HCl\xrightarrow{{}}{{K}_{2}}C{{r}_{2}}{{O}_{7}}\] \[+2KCl+{{H}_{2}}O\] So, the coefficients that balance the equation are 2, 2, 1, 2, 1.You need to login to perform this action.
