What is the cause of green powdery corrosion all over the copper wires under the plastic housing of a stove outlet and how do you cure this?

Possibly old wiring corroding. Could be caused by loose connections. May have to run new wires. Consult a licensed electrician.

How is corrosion of copper a chemical change?
Corrosion involve chemical reactions - and these are chemical changes.
5 properties of copper?
Copper ismaleableductileExcellent electrical conductor'Excellent conductor of heatFairly corrosion resistant
Is copper a thermosetting plastic?
Copper is not thermosetting - if you heat it up enough it will melt - nor is it plastic.
What is the chemical reaction in cleaning a penny?
A copper penny builds up a layer of corrosion on its outsides. Probably copper oxide. The cleaning just dissolves the outer corrosion and leaves a new outer layer of copper. CuO + HNO3 --> Cu(NO3)2 + H2O ... the copper nitrate is dissolved in the acid solution and leaves 'clean' copper behind.
What is the metal that speed up corrosion?
Any metal that is higher than iron in the electrochemical series coupled to it will speed up the corrosion. As an example, a copper pipe in contact with steel will accelerate the corrosion of the steel.
What makes copper rusty?

Why is a gold coin shiny?
it is coated in copper. copper prevent corrosion.
What metal turns green and why?
Copper turns green after a while because of weathering and corrosion. It is in general the Oxygen in our atmosphere that bonds with the copper, forming a protective layer of "green" oxydation or corrosion. Further information: Many buildings have copper-roofs. It is a metal that is easy to cut and form. It is also highly corrosion resistant because the corrosion formed also protects it from further corrosion. Acid rain however is able to wash away part of the corrosion formed. This mean that in highly polluted areas, Copper is not such a good choice. The Statue of Liberty used to be the iconic copper color.

What is the reaction of benzene cleaning agent on copper containt material?
Corrosion of the copper
What is a hypothesis for how pH in water Affects Copper Corrosion?
If the water's pH is more acidic (lower pH) then the effects of copper corrosion will be faster and more pronounce. If the water is less acidic (Higher pH) copper corrosion will take longer and be less pronounce.
Can copper turning be used to test how pH affects copper corrosion?
If copper is present, the solution will turnblue...
How do you store copper?
Copper can be stored in bottles containing water, such that none of the copper is exposed to air, as this can cause the corrosion of copper.
What are some examples of corrosion?
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.

How good is copper at resisting corrosion?
The corrosion resistance of copper is great! But if the hardness was better and the strength it would be way better than titanium in some cases (not the melting point)!!!
Characteristics of copper?
Corrosion resistance and electrical conductivity. and its metal
