Question

K+M2O = KOH + H2FeS2+ O2 = Fe2O3 + SO2H2S+ O2 = H2O + SO2​

Answer 1

2K + 2H2O --> 2KOH + H2

4FeS2 + 11O2 --> 2Fe2O3 + 8SO2

2H2S + 3O2 --> 2H2O + 2SO2​

Answer 2

It seems like you've provided a series of chemical reactions. Let's break down each reaction and balance the chemical equations.

1. K + M2O = KOH

   This is a simple replacement reaction where potassium (K) displaces another metal (M) from its oxide (M2O). To balance this equation, we need to know the specific values for M and the stoichiometric coefficients.

2. H2FeS2 + O2 = Fe2O3 + SO2

   This is a reaction involving hydrogen disulfide (H2S), iron(II) sulfide (FeS2), oxygen (O2), and iron(III) oxide (Fe2O3). It seems to be a combustion reaction. Let's balance it:

   $H2FeS2 + 5 O2 = Fe2O3 + 2 SO2$

3. H2S + O2 = H2O + SO2

   This is a reaction involving hydrogen sulfide (H2S), oxygen (O2), water (H2O), and sulfur dioxide (SO2). Let's balance it:

   $2 H2S + 3 O2 = 2 H2O + 2 SO2$

If you have any specific reactants or conditions for the first reaction, please provide them, and I can help balance that equation as well.
