Answer 2

Coefficients in Chemical Equations

Let's determine the coefficients in the given chemical equations:

1. H2S + O2 → S + H2O

The balanced equation for this reaction is:

2H2S + 3O2 → 2S + 2H2O 2. Al(OH)3 + HNO3 → Al(NO3)3 + H2O

The balanced equation for this reaction is:

Al(OH)3 + 3HNO3 → Al(NO3)3 + 3H2O 3. H2O → H2 + O2

The balanced equation for this reaction is:

2H2O → 2H2 + O2 4. HgO → Hg + O2

The balanced equation for this reaction is:

2HgO → 2Hg + O2 I hope this helps! Let me know if you have any further questions.
