How do you balance the following equation: #Ag + H_2S → Ag_2S + H_2#?

Answer:

Put a coefficient of #2# in the first #Ag#.

Explanation:

Your equation is:

#Ag(s)+H_2S(aq)->Ag_2S(aq)+H_2(g)uarr#

This is a common reaction between an acid and metal, where it produces a salt and hydrogen gas.

From here, I see that everything is balanced, except that there are two silver atoms on the right side, but only one on the left side, so we multiply #Ag# on the left by #2# to get the balanced equation:

#2Ag(s)+H_2S(aq)->Ag_2S(aq)+H_2(g)uarr#
