# NEET Chemistry Redox Reactions Questions Solved

In a balanced equation ${H}_{2}S{O}_{4}+x\text{\hspace{0.17em}}HI\to {H}_{2}S+y\text{\hspace{0.17em}}{I}_{2}+z\text{\hspace{0.17em}}{H}_{2}O$, the values of x, y, z are [EAMCET 2003]

(1) x = 3, y = 5, z = 2

(2) x = 4, y = 8, z = 5

(3) x = 8, y = 4, z = 4

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

(3) The values of x, y, z are 8, 4, 4 respectively hence the reaction is

${H}_{2}S{O}_{4}+8HI\to {H}_{2}S+4{I}_{2}+4{H}_{2}O$
