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 particle carry the charge when electricity flows on molten copper?
In molten copper, positively charged copper ions (Cu2+) carry the electric charge as they move towards the negative electrode. Electrons flow through the external circuit from the negative electrode to the positive electrode.
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.
Do copper carry current?
Yes, copper is a good electrical conductor.

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.
What is the aluminum wire equivalent to?
In the electrical trade aluminum wire is equivalent to copper wire as it is also used to carry current. To carry the same current as copper wire aluminum wire is up sized to meet the same ampacity.
What are some everyday items that contain copper?
Pennies (copper-plated zinc), objects made of brass (brass is an alloy of copper and zinc), and wires and cables that carry electricity and/or electronic signals.
