QUESTIONS AND EMS 1. Complete the equations of the following reactions and balance them: (a) K_(2)S+KMnO_(4)+H_(2)SO_(4)=S+ldots (b) KI+K_(2)Cr_(2)O_(7)+H_(2)SO_(4)=I_(2)+ldots (c) KMnO_(4)+H_(2)O_(2)=ldots

Let's correct and balance the equations step by step:<br /><br />(a) $K_{2}S + KMnO_{4} + H_{2}SO_{4} = S + K_{2}SO_{4} + MnSO_{4} + H_{2}O$<br /><br />(b) $2KI + K_{2}Cr_{2}O_{7} + 4H_{2}SO_{4} = I_{2} + K_{2}SO_{4} + Cr_{2}(SO_{4})_{3} + 4H_{2}O$<br /><br />(c) $2KMnO_{4} + 5H_{2}O_{2} + 3H_{2}SO_{4} = 2MnSO_{4} + 5O_{2} + K_{2}SO_{4} + 4H_{2}O$<br /><br />These balanced equations correctly represent the stoichiometry and conservation of mass for each reaction.
