    The set of numerical coefficients that balances the equation , \[{{K}_{2}}C{{r}_{2}}{{O}_{4}}+HCl\xrightarrow[{}]{{}}{{K}_{2}}C{{r}_{2}}{{O}_{7}}+KCl+{{H}_{2}}O\] is:

    A) 1, 1, 2, 2, 1        

    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.
