Explanation:
The name for the compound Ag2S is Silver sulfide.
<u>Explanation</u>:
- The name for the compound Ag2S is Silver sulfide. It is the inorganic compound with the formula Ag
2S. A dense black solid, which is used as a photosensitizer in photography.
- Silver sulfide is insoluble in most solvents but is degraded using robust acids where the bonds have a low ionic of approximately 10%.
- It has a molar mass of 247.80 g / mol. The look is the grayish-black crystal, odorless, soluble in aqueous HCN, aqueous citric acid with KNO3 and insoluble in acids, alkalies.

The bubbles that were observed after the mixing of the two substances is one of the products of the reaction. It is the carbon dioxide that is produced. To determine the mass of this gas produced, we need to remember the Law of conservation of mass where mass cannot be created or destroyed. With this, we can say that the total mass that goes in a process should be equal to the mass that is goes out of the process no matter what the reaction is. We do as follows:
Mass of reactants = mass of products
11.00 + 44.55 = 51.04 + mass of carbon dioxide
mass of carbon dioxide = 4.51 g
