It's an Ionic bond
No, AG2S (silver sulfide) is not soluble in water.
Ag2S is Ionic. If it has a Non-Metal and a Metal it is Ionic. If it only contains non-metals it is noniconic. Well that simple rule is OK- however a better guess is made if you conside the electronegativities of Ag and S - they are quite close (they need to be well apart for ionic bonding) so Ag2S has considerable covalent character.
The color of Ag2S (silver sulfide) is typically black or dark grey.
The above reaction is a combination type reaction between silver (Ag) and sulfur (S)
The tarnish of silver is mainly caused by the formation of silver sulfide (Ag2S) when silver reacts with sulfur compounds in the air. The chemical equation for this reaction is: 2Ag + H2S + O2 → Ag2S + H2O
The balanced equation for the reaction between zinc (Zn) and silver sulfide (Ag2S) is: Zn + Ag2S -> ZnS + 2Ag

To find out how much silver can be produced from 125g of Ag2S, you need to consider the molar mass of Ag2S, which is 247.8 g/mol. This means that 1 mole of Ag2S produces 2 moles of silver (Ag). Therefore, you can calculate the amount of silver produced from 125g of Ag2S using stoichiometry.
The mole ratio of H2S to Ag2S can be derived from the balanced chemical equation for the reaction between hydrogen sulfide (H2S) and silver sulfide (Ag2S). The balanced equation is typically represented as 2 H2S + Ag2S → 4 Ag + 2 H2O + 2 S. From this equation, the mole ratio of H2S to Ag2S is 2:1.
The above reaction is a combination type reaction between silver (Ag) and sulfur (S)
To balance the equation Ag + H2S → Ag2S + H2, you need to make sure that the number of each type of atom is the same on both sides of the equation. Start by adding a coefficient of 2 in front of Ag and Ag2S to balance the silver atoms. Then, balance the hydrogen atoms by adding a coefficient of 2 in front of H2. Finally, balance the sulfur atoms by adding a coefficient of 2 in front of H2S. The balanced equation is 2Ag + 2H2S → Ag2S + H2.
Yes, silver(I) sulfide (Ag2S) is a solid at room temperature. It typically appears as a black or dark brown crystalline substance. Ag2S is used in various applications, including in the production of silver and as a semiconductor material.
