Unbalance: Agno3+H2s--->Ag2s+Hno3

Unbalance: AgNO3+H2S--->Ag2S+HNO3

 

Good Day

Given:

    AgNO3 + H2S    →    Ag2S + HNO3

                ↓                                 ↓

         Reactant                    Product      

Type of reaction: double replacement or double displacement reaction

To balance:

Based on the law of conservation of mass, the mass of reactant is equal to the mass of the product. It also means the number of atoms in each element of reactant and product are equal.

                         2AgNO3 + H2S    →    Ag2S + 2HNO3  

                                  Ag = 2                       Ag = 2

                                NO3 = 2                    NO3 = 2

                                   H = 2                        H = 2

                                  S = 1                           S = 1

Hope it helps...=)
