Silver sulfide Ag2S -Molar mass: 247.9 g/mol .
Thus 2 moles of silver will react with one mole of sulphur.
Silver Atomic Mass: 107.9 so 4 g = 0.0370713623725672 of a mole
Sulphur Atomic mass 32.1 so 4 g= 0.1246105919003115 of a mole
Ag2S -Molar mass: 247.9 g/mol - which is 32.1 g of Sulphur + 2 times 107.9 = 215.8 g of Silver
Therefore 32.1/215.8 = 0.1487488415199259 the ratio of the masses
Therefor Silver 4 g * 0.1487488415199259 = 0.5949953660797034 g of Sulphur
Therefore the mass of Silver sulphide produced is 4.5949953660797034 grams,
With 4-0.5949953660797034 = 3.405004633920297 g of sulphur left over.

What is the product when silver reacts with air?
Silver oxide is photosensitive and silver can be separated.
Is silver tarnishing a physical change?
No, it is a chemical change. The tarnish seen on silver is silver sulfide which formed by the silver reacting from small amounts of hydrogen sulfide in the air. So silver sulfide has been created by a chemical reaction.
What is a balance chemical equation for Silver (Ag) tarnishes when it reacts with hydrogen sulfide (H2S) molecules in the air?
Ag2O----Actually, silver oxides exists as silver peroxide (AgO) or silver oxide (Ag2O)
How is Silver Collected?
Practically all the silver produced in Europe is obtained from the lead sulfide ore, galena. In the United States relatively few mines are worked for their silver alone -the silver is mined in conjunction with lead, copper, and zinc.
Is tarnish of silver a physical or chemical change?
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
When does silver sulfide form?
Whenever silver is in the presence of certain sulphur compounds, particularly hydrogen sulphide.
Why do silver turn blackish after use?
It reacts with sulphur present in the atmsphere and forms silver sulphide which is black in colour
What is the product when silver reacts with air?
Silver oxide is photosensitive and silver can be separated.
Which is more durable silver or gold?
Gold is more durable than Silver. Silver reacts with Sulphur dioxide in air and gets blackened. This is not the case with gold. Gold rarely reacts and does not easily make compounds.
What is Ag2S in chemistry?
Ag2S is its own compound: silver sulfide.If you mean what elements are in Ag2S, they are silver, and sulfur.
What color does silver become when oxidized?
Black (Silver Oxide, Ag2O, Only with pure Oxygen)
Why do some lotions and cosmetics tarnish silver on contact?
Because it contains Sulfur and sulfur reacts with the silver forming hydrogen sulfide, which causes the tarnish
Is formation of silver sulfide when silver reacts with sulfur in the air a physical change?
chemical, specifically an "oxidation" reaction (even though oxygen is not involved).
What causes silver coins to tarnish?
Tarnish occurs when silver reacts with oxygen or hydrogen sulfide in the air, moisture, skin oil from being handled, and other contaminants.
How much silver phosphate is produced if 10g of silver acetate reacts with excess sodium phosphate?
gay
Is silver a sulfide?
Silver sulfide is an ionic compound, and is not a metal.
What is the formula for silver (I) sulfide?
The formula of silver sulfide is Ag2S.
