Answer:
By giving electricity to copper compound solution.
Explanation:
Electrolysis is one of the major way of refined copper. The copper containing solution has two electrodes.i) positive electrodes called anode. ii) negative electrodes called cathode. When electricity is pass into the copper containing solution electrolysis process is starts and impure copper is formed in anode and pure copper is formed in cathode.
So, We can get pure copper in cathode through electrolysis.

Metals are the type of elements that are most likely to form more than one type of ion, for instance iron can form the ion of Fe^2+ or Fe^3+.
The bare rock will erode, once it erodes the rock will no longer be bare cause eroded sediment will cover it.
Answer:
hydrocarbons are compounds which contains Hydrogen and carbon
There are 2.06 x 10²⁴ atoms
<h3>Further explanation
</h3>
The mole is the number of particles (atoms, molecules, ions)contained in a substance
1 mol = 6.02.10²³ particles
Moles can also be determined from the amount of substance mass and its molar mass
