___au2s3 ___h2 → ___au ___h2s
liberstina [14]
The best way to balance an equation is to balance one atom at a time.
You start with two Au atoms on the left, so you know the coefficient of Au on the right has to be 2. So at first we get,
Au2S3 + H2 --> 2Au + H2S
Then, notice you have 3 sulfur atoms on the left, so you need three on the right.
Our equation becomes
Au2S3 + H2 --> 2Au + 3H2S
Lastly, we now have six hydrogen atoms on the right, and only two on the left, so we assign a three to the H2 on the left
Au2S3 + 3H2 --> 2Au + 3H2S Is the balanced final equation.

How will the boiling point of a liter of water containing 1 mole of sodium chloride (NaCl) compare with that of a liter of water
Alex Ar [27]
The boiling point of the calcium chloride CaCl2 solution will be higher than that of the boiling point of the sodium chloride NaCl solution, because more molecules are present in the CaCl2 solution since CaCl2 dissociates into three ions while NaCl only dissociates into two ions.
