What test would you perform to distinguish hematite form copper how would you carry out this test?

A few things used to identify minerals are streak tests, hardness, cleavage, solubility, magnetic.
Streak test: When you scrape a mineral on a streak plate it leaves behind powder of a certain color. Hematite leaves a red streak. I don't know what streak copper has.
Hardness test: minerals have different hardness, their ability to be scratched or scratch. this can be determined by seeing if you can scratch a mineral with your finger nail or if the mineral will scratch a piece of glass. I don't know if this test will do much good though in determining copper from hematite.
Cleavage: Cleavage in mineralogy refers to when you break a mineral, how it fractures. Does it fracture into cubes, rhombus shapes, conchoidal, etc.
Solubility: copper is soluble in acids and forms green-blueish solutions, hematite is insoluble.
Magnetic: hematite is sometimes slightly or strongly magnetic. copper is not magnetic
After you test your samples, look up in a book or manual to see which mineral(s) have matching properties.

Where can one buy a copper bracelet?
Copper bracelets can be purchased from a variety of stores. Drugstores such as Shoppers Drug Mart and Walmart, carry copper bracelets for the claimed medical benefits.
Is copper white a conductor or insulator?
Copper is a metal, so it has metallic bonding. This means that the electrons are free to move & carry a current. So copper is a good conductor of heat & electricity.
What is that copper item the olympic sign bearers carry?
A copper petal of which there are 204, one for each country/territory, that are combined to form the cauldron of the Olympic flame.
What is the charge for copper hydroxide?
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.

How much ac current can 2 copper conducters carry?
It depends on the cross-sectional are of the conductors -the bigger, the more current they can carry.

Copper is a metal, so it has metallic bonding. This means that the electrons are free to move & carry a current. So copper is a good conductor of heat & electricity.
What is a conductor in the scientific way?
A conductor is something that can carry the electrons (electricity) through it. An example is copper. That is why copper is used for wiring. it is a good conductor.
