No. If you have one, the most likely case is that it's a normal nickel* that someone plated. In that case it'll weigh just about the same amount as a normal nickel. The other and less likely possibility is that it was struck on a planchet (blank) intended for a foreign coin. In that case it will almost certainly weigh a different amount. You'd need to have it examined in person by a dealer or other expert. (*) I had to change your question so it would show up correctly in searches. The coin is a nickEL rather than a nickLE.
No.
All nickels except the famous "war nickels" from 1942-45 are made of 25% nickel and 75% copper. If your coin is copper colored it was either plated or exposed to something like heat or a chemical that caused it to tarnish.
Yes. However, the House of Representatives recently passed a bill allowing for pennies and nickels to be made of steel. It is not law yet so nickels are still 75% copper.
All US nickels are 75% copper, I have seen many nickels that appear very dark and look like they are all copper but ther not.

Nickel cannot replace copper in copper II sulfate because nickel is higher in the electromotive series than copper.
nickel and copper are elements that can be magnetized
No - copper is a better conductor than nickel.
copper has more protons than nickel
copper has more protons than nickel
There are no "silver" 1977 coins...they are copper-nickel Eisenhower coins and they are worth $1.00

The same thing they were made of in 1965 a copper nickel alloy of .750 copper & .250 nickel on the outer layers bonded to a core of pure copper.
25p or if in silver around £20. They were struck in very large numbers in cupro-nickel (an alloy of copper and nickel).
It is made of copper and nickel. A 1949 NICKEL is made from copper & nickel.
Dwight D. Eisenhower. The coin is actually made of copper-nickel, not silver.

Okay, let's take the basics: There is no such thing as "copper sulfate baking powder", as it would be poisonous. I can think of no way to relate elemental nickel to the fictitious "copper sulfate baking powder".
Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.
mostly copper and nickel. a nickel is made mostly of copper. in fact, it is 75% copper and around 25% nickel!
Copper-nickel is an alloy of copper and nickel which have different densities. You need to know the proportions of each metal in the alloy to determine its density.
