    In a balanced equation \[{{H}_{2}}S{{O}_{4}}+x\,HI\to {{H}_{2}}S+y\,{{I}_{2}}+z\,{{H}_{2}}O\], the values of x, y, z are                 [EAMCET 2003]

    A)                 x = 3, y = 5, z = 2

    B)                 x = 4, y = 8, z = 5

    C)                 x = 8, y = 4, z = 4

    D)                 x = 5, y = 3, z = 4

    Correct Answer: C

    Solution :

               The values of \[x,\,y,\,z\] are 8, 4, 4 respectively hence the reaction is                                 \[{{H}_{2}}S{{O}_{4}}+8HI\to {{H}_{2}}S+4{{I}_{2}}+4{{H}_{2}}O\]
