Why do we use copper for electrical wires? Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity. These metals are both ductile and relatively resistant to corrosion, but they also have different properties which make them useful for various applications.
What is the reaction when copper carbonate is heated? Copper carbonate decomposes (breaks down) when it is heated into copper oxide and carbon dioxide.
What happens when a carbonate is heated? When metal carbonates are heated, they break down to form the metal oxide and carbon dioxide gas. … The stability of the metal carbonates can be related to the reactivity series of metals. The higher up the series a metal is, the more reactive the metal is and so the more stable the metal carbonate is.
Can copper pipes last 100 years? Well, some last 50-70 years, but depends on the type of Copper piping. There are M-type, L-type, and K-type. K-type lasts the longest, over 100 years, but the L-type is better for the residential home.

Can i use copper pipe for electrical conduit?
If you mean as a conduit to run electric cables in yes you can but its waste of money and copper is not so strong as steel to withstand mechanical damage. You should also make sure you connect the copper pipe, if using as a conduit, to Earth. You can’t use is it as a conductor though as it would be uninsulated.
Can copper ions be reduced by zinc?
These types of reactions are called direct redox reactions because the electrons flow directly from the atoms of one metal to the cations of the other metal. However, no reaction will occur if a strip of copper metal is placed into a solution of zinc ions, because the zinc ions are not able to oxidize the copper.

First, copper is oxidized to copper oxide with heat, then it transfers this oxygen to acetone returning to its metallic form. In the next reaction with acetone, the copper surface becomes bright because of the transfer of the oxygen and begins to glow red hot because of the energy that’s released from the reaction.
