Question

Enter the coefficients that balance the tarnishing

reaction equation. (Type 1 for no coefficient.)
I Ag(s) + H2S(g) – Ag,S(s) + H2(g)

Answer 1

2 1 1 1

Step-by-step explanation:

When silver tarnishes, a single replacement reaction happens.

Answer 2

2Ag(s) + 1H2S(g) → 1Ag2S(s) + 1H2(g)

Step-by-step explanation:

Step 1: Data given

Ag(s) + H2S(g) → Ag,S(s) + H2(g)

Ag has and oxidation number of +1

S has an oxidation number of -2

H has an oxidation number of +1

Step 2: The balanced equation

Ag+ + 2H+ + S^2- →

The silver ion and the sulfur ion will bind, but we need 2 silver atoms to bind with 1 sulfur atom.

2 H- atoms will appear as H2.

The balanced equation is:

2Ag+ + 2H+ +S^2- → Ag2S + H2

2Ag(s) + 1H2S(g) → 1Ag2S(s) + 1H2(g)
