## Chem Question……confused….?

A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer heated the coin, which weighed 14.0 g to 100°C in boiling water and then dropped the hot coin into 28.5 g of water at T = 17.0°C in an insulated coffee-cup, and measured the rise in temperature. If the coin was really made of silver, what would the final temperature of… Continue reading

## If the coin was really made of silver, what would the final temperature of the water be (in °C)?

A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer heated the coin, which weighed 17.0 g to 100°C in boiling water and then dropped the hot coin into 25.5 g of water at T = 16.5°C in an insulated coffee-cup, and measured the rise in temperature. If the coin was really made of silver, what would the final temperature of… Continue reading

## help in chemistry…?

Canadian 10¢ and 25¢ coins are made of pure nickel which has a density of 8.902 g/cm3. Suppose each dime weighs 2.02 g and each quarter weighs 5.05 g. A small collection of dimes and quarters are submerged in 10.00 mL of water in a graduated cylinder causing the water level to rise to the 18.74 mL mark. What is the combined monetary value (in Can\$) of those coins?… Continue reading

Let’s take a look at what I think are the gems of Canadian coin collecting. These gems are the gold and silver coins to begin with. The value of a gold or silver coin is not just evaluated on the rarity of the coin only, but is also evaluated on the metal… Continue reading

i have a 1944 nickel in good condition. only a scratch on the back (small). its in awesome condition other than that.
i’m just curious as to if it’s a rare coin or if it’s worth anything.
