I’m in an engineering class and I’m trying to invent a heated covering for a gear shift. I need to know if a 12V outlet will heat copper wires enough to brun through cotton. Or will it be better to use car seat material or those potable massagers material. An adapter will come from the outlet and into the covering to heat the interior copper wires, thus heating the gear shift. Am I clear or confusing?
when copper wire is heated, too much amperage, it will burn through the rubber coating that is specifically made for it. so yeh you would have a fire on your hands. like some others have said copper is a conductor. heating elements are made of resistors. that’s why they heat up. the resistance to current flow causes heat. you also need a thermostat to control the current flow. if not you’ll just have a nice carbecue
Can a copper wire that is powered to a 12V car outlet brun through cotton?
How do you extract copper from copper sulphide?
I understand the initial process being thermal decomposition changing the compound into copper oxide. I would relish in the knowledge of how to then change this into copper. Please help. Thank you.
not sure if this is helpful..im a little rusty

What does copper sulfate do in a reaction when acting as a catalyst?
The experiment I am focusing on is between yeast and hydrogen peroxide, and the rate oxygen is being produced.
I am testing to find out how the concentration of copper sulfate in this reaction affects the rate of reaction (oxygen being produced)
I want to know what copper sulfate actually does when being a catalyst? How does it speed up the rate of reaction?
It is the enzyme catalase or peroxidase which brings about such changes and not the copper ion. However, Cu++ ion forms a complex with the enzyme and this enzyme-Cu++ complex (Protein-copper complex) takes part in the catalysis.

58 foot of copper AC pipe were taken from the house we about to purchase. How much will it cost to replace?
we are buying a HUD home. had the house inspected today and one of the issue we found was the copper pipe for the Air Condition inside the house were stolen. 58 foot of it were gone. we only have a week before closing. my question is how much would it cost to have it replace by professional Air Condition installer? i was told by the home inspector that the copper pipe/copper line were missing. Thank you in advance for your time.
I am from Dallas Texas area 
I can tell you it ant gonna be cheap with as high as copper prices are
What is the empirical formula of the copper sulfide?
Copper will react with sulfur to form a copper sulfide. If 1.500g copper reacts with sulfur to form 1.880g of copper sulfide, what is the empirical formula of the copper sulfide?
It can be either CuS or Cu2S since the quantity of S is not specified. If sulphur is a limiting reagent, then is will be CuS. If sulphur is in excess, then is it Cu2S.
To claim it must be one or the other is just naive.
CuS is copper sulphide or copper(II)sulphide
Cu2S is cuprous sulphide or copper(I)sulphide
To demonstrate that it can be either:
Cu(s) +S(s) –> CuS
1.880 g (0.0197 mol) CuS is produced
so 0.0197 mol each of Cu and of S reacted.
mass Cu reacted (0.0197g x 63.546 g/mol) = 1.252g
0.248g Cu remains unreacted
mass S reacted (0.0197g x 32.065 g/mol) = 0.632g
The product copper(II)sulphide is CuS
Sulphur is the limiting reactant.
ALTERNATIVELY,
2Cu + S –> Cu2S
1.880 g Cu2S is 0.0118 mol
so 0.0236 mol (1.500g) Cu reacted
and 0.0118 mol (0.378g) S reacted
The product is copper(I)sulphide
So both calculations work!
since the quantity of sulphur was not given, we could not know which applied, except that the name of the product was indicated, copper sulphide, but not the oxidation state.
At a higher level chemistry (questioner does not give his/her level) you would be expected to give this answer or something similar.
If you are only at an elementary level in your studies, then you will probably jump at the first answer that occurs to you and assume that it is the only correct answer.

Is Copper Toxic? My husband wants to put a patinaed copper skin on our range hood and island.?
I think this would look awesome since it would match the bronze drawer pulls. I have heard that the patina can be toxic. Or is just drinking from copper pipes that is bad? Advice please.
Any metal ingested in a large enough quantity is toxic, which applies to many other substances, also.
Drinking from copper pipes is not bad. The problem was/is the lead-based solder used in many of them.
P.S. bronze also contains copper and how many pennies do you handle a day without poisoning yourself yet?
