The balanced equation for the reaction between iron sulfied and water is best represented by?​
nika2105 [10]

FeS  +   H₂O    →    FeO   +    H₂S

Explanation:

  Iron Sulfide = FeS

  Water = H₂O

                FeS  +   H₂O    →    FeO   +    H₂S

To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations

                 aFeS  +   bH₂O    →    cFeO   +    dH₂S

 a,b,c and d are the coefficients needed to balance up the equation:

      Conserving Fe: a = c

                           S:  a = d

                           H:  2b = 2d

                           O:  b = c

let a = 1, c= 1, b = 1 d = 1

     The balanced equation is:  FeS  +   H₂O    →    FeO   +    H₂S
