Question

is 2Ag+S=Ag2S a balanced equation?

Answer 1

there are 2 Ag on both sides of the eq
there are 1 S on both sides of the eq

yes it is a balanced equation

if there were 3 Ag on one side and only 2 Ag on the other, then it would not be a balanced equation

Answer 2

Yes, the given equation is properly balanced. In order to see if an equation is balanced, we need to make sure there is the same number of each element on each side. First, let's check the Ag. On the left side, we have 2 Ag and on the right we have 2 Ag as well so the Ag is balanced. Then, for the S, we have one S on the left side and one S on the right side as well, so the S is balanced. Since both Ag and S are balanced, the overall equation is balanced.

I hope this helps.
