Question

balance ionic equation
Mn2+ +H2s ----------> MnS + H+

Answer 1

Mn2+ + H2S—> MnS + 2H+
hence, balanced
hope it helped!

Answer 2

The complete balanced equation is as follows:

Mn2+ H2S ----------> MnS +2 H+

The procedure is explained as follows:

The main point is that we should balance all the elements correctly on both the sides( the number should be equal on both the sides).

As we observe in the original equation:

Manganese( Mn) and Sulfide( S) are same on the both the sides but the Hydrogen( H) is different. The number of H on the reactant side is 2 whereas on the product side is 1, therefore this needs to be balanced in the equation.
