Answer 2

Balancing the Chemical Equation H2S + AgNO3 = Ag2S + HNO3

The chemical equation to be balanced is:

H2S + AgNO3 = Ag2S + HNO3

To balance this equation, we'll use the method of electron balance and determine the oxidation states of the elements involved.

Oxidation States

- The oxidation state of hydrogen (H) is usually +1, except when bonded to metals in binary compounds, where it is -1. - The oxidation state of sulfur (S) in hydrogen sulfide (H2S) is -2. - The oxidation state of silver (Ag) is +1. - The oxidation state of nitrogen (N) in silver nitrate (AgNO3) is +5. - The oxidation state of sulfur (S) in silver sulfide (Ag2S) is -2. - The oxidation state of nitrogen (N) in nitric acid (HNO3) is +5.

Balancing the Equation

1. Balance the atoms other than hydrogen and oxygen. In this case, we have sulfur and silver. 2. Balance the oxygen atoms by adding water molecules. 3. Balance the hydrogen atoms by adding H+ ions. 4. Balance the charge by adding electrons.

The balanced chemical equation is:

H2S + 2AgNO3 = Ag2S + 2HNO3

This equation is now balanced according to the method of electron balance.
