Question

What is the coefficient for Ag when the following equation is properly balanced?Ag + H2S + O2 → Ag2S + H2Oa.)2b.)4 c.)6d.)8

Answer 1

4. Option B is correct

Explanations:

Given the chemical equation below;

`Ag+H_2S\rightarrow Ag_2S+H_2O`

Chemical equation is known to be balanced if the total atom of elements are on both the reactant and product are equal.

`4Ag+2H_2S+O_2\rightarrow2Ag_2S+2H_2O`

From the balanced chemical equation, the coefficient for Ag is 4
