The sum of the coefficients for all reactants and products is: 12.

Here, we first need to balance the equation of the reaction between Fe2S3(s) and H+.

  • The chemical equation yields H2S and Fe3+ as follows;

  • Fe2S3(s) + H+ (aq) ------> H2S + Fe3+(aq)

  • Balancing the equation consequently yields;

  • Fe2S3(s) + 6H+ (aq) ------> 3H2S + 2Fe3+(aq)

The sum of the coefficients for all reactants and products is therefore;

Sum = 1 + 6 + 3 + 2.

Sum of coefficients = 12
