Question

What are the coefficients that balance the following chemical equation? ___Ag + ___ S → ___Ag2S

Answer 1

Answer:

1Ag+2S⇔1Ag2S

Explanation:

The first step is to see how many of each element are on each side of the equation. There is one silver on the left and one silver on the right, so you can leave those alone. However, there is one sulfur on the left and two on the right. You cannot multiply the right by 2 because then that would upset the balance of the silver, but you can multiply the sulfur by 2. Therefore, the equation should be 1Ag+2S⇔1Ag2S. Hope this helps!

Answer 2

Answer:

$2Ag+S$ → $Ag_2S$

Explanation:

In order to balance this, we want to have the same number of elements on each side of the equation.

On the right side, we see that we have two atoms of Ag and one atom of S. So on the left, we want to have 2 atoms of Ag and 1 atom of S. We can put 1 in front of S and 2 in front of Ag:

2Ag + 1S → 1$Ag_2S$

We actually don't have to explicitly write the "1":

$2Ag+S$ → $Ag_2S$

Hope this helps!
