balance the half-reaction. (Type your answer using the format CO2 for CO2, [NH4]+ for NH4+, and [Mg]2+ for Mg2+. Use the lowest possible coefficients.)

I am sooo confused

(a) S(s) --> H2S(g)

thanks

To balance a half-reaction, follow these steps:

1. Write down the unbalanced half-reaction.
(In this case, the unbalanced half-reaction is S(s) → H2S(g))

2. Identify the atoms that are unbalanced.

In this half-reaction, the only atom is Sulfur (S), so we need to balance the number of Sulfur atoms on both sides.

3. Balance the atom that is unbalanced by adjusting the coefficients in front of the species.

In this case, we can see that there is one Sulfur atom on the left side and only one Sulfur atom on the right side. So, the number of Sulfur atoms is already balanced.

4. Finally, verify that the number of atoms and charges are balanced on both sides.

In this case, since we have only balanced the Sulfur atom, there are no additional atoms or charges to balance.

So, the balanced half-reaction is:
S(s) → H2S(g)

No further balancing is required for this particular half-reaction.
