United States of America 3 Cents
The coin is NOT silver. Most circulated coins are valued at $1.00-$3.00. The 1901 Liberty Head nickel is not rare or scarce.
"III" is the coin's denomination, 3 cents. While it seems strange to have that denomination in a 10-based system, it was issued specifically for buying postage stamps.1853 is one of the more common dates for silver 3¢ pieces but it's still nicely priced. Numismedia lists the following approximate retail values as of 09/2009:Very worn condition - $25Moderately worn - $46Slightly worn - $53Almost no wear - $140Uncirculated - $185-6600 depending on quality
No 1964 silver quarter should have a copper layer and they all should be 90% silver, although it is possible that your quarter has tarnished or toned odd and just appeared to look non-silver. Both copper-nickel clad and silver quarters were produced in the mid-1960s with the clad ones being dated 1965 and later while the silver ones were dated 1964, so theoretically it could be struck on a copper-nickel planchet. I would weigh the coin, a silver one should weigh about 6.25 grams (naturally a worn quarter would weigh less) while a copper-nickel one should weigh much less, about 5.67 grams.
U.S. silver dollars issued from 1836 to 1935 have the following approximate dimensions: Diameter - 38.1 mm; early dates were slightly larger Weight - 26.7 gm Composition - 90% silver, 10% copper There were slight variations over that century but the above values are the most common dimensions.
Ag2S is its own compound: silver sulfide.If you mean what elements are in Ag2S, they are silver, and sulfur.
Silver sulfide is an ionic compound, and is not a metal.
The formula of silver sulfide is Ag2S.
Silver sulfide is an ionic compound, and is not a metal.
Silver sulfide, Ag2S is a chemical compound.
2 Silver Sulfide molecules (silver tarnish)
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.
Silver sulfide is a salt. but common "salt" or table salt is sodium chloride.
The silver sulfide is Ag2S.
Silver sulfide is composed of silver, a metal, and sulfur, a non-metal; therefore, it is an ionic compound and a salt.
Ag2S = silver sulfide
Ag2SMainly Silver(I) Sulfide = Ag2S
