What is the historic price ratio between gold and silver?
10:1 is the natural ratio and 16:1 was the first pegged ratio
Is there a silver ratio if there's a golden ratio?
yes, if the golden ratio is ((square root 5) +1)/2, then the silver ratio is (square root 2) +1. as the golden ratio is represented by phi, the silver ratio is represented by deltas. as two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one, two quantities are in the silver ratio if the ratio between the sum of the smaller plus twice the larger of those quantities and the larger one is the same as the ratio between the larger one and the smaller.
What materials are used in a 1962 quarter?
The same as in all silver coins minted in up to 1964 - an alloy of 90% silver and 10% copper. Due to the rising price of silver, in 1965 the Mint changed the composition of the dime and quarter to a 3-layer "sandwich" consisting of outer layers of 25% nickel / 75% copper bonded to a pure copper core. Halves were changed to outer layers of 80% silver bonded to a core of 40% silver. Unfortunately the price of silver continued to rise and so many halves were melted that they effectively disappeared from circulation. In 1971 the Mint belatedly switch them to the same composition as dimes and quarters but it was too late to restore the denomination. The new Sacagawea and Presidential Series dollars are made of a manganese-brass-copper sandwich, giving them a golden appearance.
How much silver is in a Roosevelt dime?
Roosevelt dimes dated 1946 to 1964 are made of 90% silver and 10% copper. They contain about 0.0714 troy ounces of silver (or about 2.22 grams). So to find their melt value, multiply the price of one ounce of silver by 0.0714. For example, if the price of silver is $15 per ounce, the coins would contain about 0.0714 * 15 = $1.07 worth of silver.Depending on the coin's date, mint mark, and condition it may be worth more to a collector.Dimes dated 1965 and later don't contain any silver at all, just copper and nickel.
How much is a 1964 pure silver dime worth?
The U.S. never made 100% silver coins for circulation. The metal would be too soft for daily use. All silver coins had at least 10% copper in them. Dimes dated 1964 and earlier contain about 0.07 ounces of silver. The price of silver changes so you'd need to search on terms such as SPOT PRICE SILVER to get the most current value, then multiply the price per ounce by 0.07. For example, at $14/oz a 1964 dime contains about $1 worth of silver.
If silver is a better conductor than copper then why is copper wire used in daily life instead of silver wire?
The price of copper today is $3.43 a pound. The price of silver today is $12.90 an ounce. Copper is much cheaper.
Is silver cheaper than copper?
No. At the moment the price of copper is US$7,230 per metric tonne. The price of silver is about US$28.10 per Troy ounce, which is US$899,000 per metric tonne. Silver is about 124 times the price of copper.
From this reaction 127.1 grams of copper will produce how many grams of silver?
To calculate the amount of silver produced, first find the molar ratio between copper and silver in the balanced chemical equation. For example, if the reaction is 2Cu + AgNO3 -> Cu(NO3)2 + 2Ag, the ratio is 2 moles of silver for every 2 moles of copper. Then, calculate the molar mass of silver (Ag) and use the molar ratio to determine the amount of silver produced from 127.1 grams of copper.
What is the melt value of a silver 1964 quarter?
As of May 24 2011 the melt value of a 1964 quarter is $6.47. This price will change as the price of silver and copper changes. This answer is based upon silver at a spot price of %35.77 per oz and copper at $4 per pound.
What is the historic price ratio between gold and silver?
10:1 is the natural ratio and 16:1 was the first pegged ratio
How many grams of copper will react to completely replace silver from 666mL of a 1.5M solution of silver nitrate?
To completely replace silver in the solution with copper, you would need an equal number of moles of copper to the moles of silver present. Calculate the moles of silver in the solution using the concentration and volume given. Then use the mole ratio between copper and silver to determine the moles of copper needed, and convert this to grams.
What is a silver ring with 925 DS on it worth?
the 925 stamp means that its sterling silver, has something to do with the ratio of silver with copper. the DS im trying to figure out for my ring as well... selling price of that ring? prolly like 15-30 bucks second hand.
Why do you use copper for electrial wiring?
Because the price of silver would shock you and copper is much less expensive.
Why is copper preffered to silver and gold for home wiring?
Price is a major consideration!
Mole ratio between silver and copper?
The mole ratio between silver and copper in a chemical reaction can be determined from the balanced equation. For example, in the reaction 2Ag + CuSO4 -> Cu + Ag2SO4, the mole ratio between silver and copper is 2:1, meaning that 2 moles of silver react with 1 mole of copper sulfate to form copper and silver sulfate.
Why do you not use silver for conducting electricity?
For electrical conductivity silver has not much advantage copper is much cheaper. The electrical conductivity advantage for silver is in the ratio 63.0 to 59.6. Silver 18.50 USD/oz Copper 3.8 USD/lb Note the different units for the comparison.
How much silver is in a 1924 US silver dollar?
All Peace and Morgan silver dollars contained 24.03 gm (0.7735 oz) of silver when new. That was alloyed with copper in the ratio 90% / 10%.
