As of 2005, around 15 million tons of copper were being produced each year from mineral extraction. This number has been steadily growing for the last 100 years (although copper has been used by humans for over 10,000 years, 95% of all copper ever produced has been extracted since 1900).

Although there are vast amounts of copper in the earth's crust, only a tiny fraction of it can be mined in a practical and cost-effective way using current technology. This viable copper reserve is estimated to last about 60 years at current projected growth rates. Recycling of copper is, therefore, an important part of copper production and will continue to be so.

Copper oxide is produced by heating copper and oxygen together to produce a black solid. This solid is copper oxide.

Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.

The particles in copper are close together because it is a type of solid. Solids have a definite shape and mass. Copper is a type of metal, which is a great conductor. Any item with hardness is a solid, for copper is a solid

Copper is a metal & solid

Solid copper reacts with solid sulfur to form Copper(I) sulfide. 2Cu(s)+S(s) -> Cu2S(s)

Copper is a metallic solid and a conductor.

If you are considering just the mass of the solid then no, only the amount of moles reacted for each compound will be the same. Since the molecular weight for Copper (ii) is higher than iron (ii) the mass of the solid (Cu) will increase slightly.

There are 2 forms of Copper(II) Sulphate, each with a different molar mass. * Copper(II) Sulphate Pentahydrate (CuSO4.5H20) This is the more common, blue, crystalline solid. it has a molar mass of: 249.7g mol-1 * Anhydrous Copper(II) Sulphate (CuSO4) This is less common to come across, it is a white powdery solid,and can be obtained by heating the pentahydrated form. Molar mass: 159.6g mol-1

Copper sulfate in the solid form are crystals

Yes. Copper compounds are all solid.

At room temperature copper is a solid.

The mass of copper is 63.5

Copper Sulphate is a blue crystalline solid.

copper (II) carbonate is a solid

Yes, copper(II) oxide is a solid at standard and room temperature. Copper(I) oxide is also a solid in these conditions as well.

The copper salt produced by the reaction of the copper with nitric acid?

An exothermic reaction occurs (this is when heat is produced). There's a link between the mass of copper sulphate and the temperature rise of the water.

No, copper is a solid metal.

Copper can be found in a solid, liquid, or gaseous forms. However, at normal temperatures, copper is a solid.

The mass of solid AgBr that is produced when 100.0 ml of 0.150 M AgNO3 is added to 20.0 ml of 1.00 M NaBr 2.82g.

63.546 is the gram atomic mass of copper.

To get the answer just remember that in chemical reactions the total mass of all the parts before the reaction must be the same as the total mass of all the parts after the reaction.
