Your old wiring has 2 "hot" wires and a ground. Your new appliance needs 2 "hot" wires, a Neutral, and a ground. Please consult an electrician.
Black wire to copper screw, white wire to silver screw, bare copper ground wire to green ground screw.
Connect black to black, red to red, white & green, to green.
On a 110 volt circuit, Black is hot, White is neutral, Green or bare Copper is ground. . Connect Black to the gold screw, White to the silver screw, and bare copper ground to the Green ground screw on the receptacle. On a 220 Volt circuit Black & Red are both hot, each carrying 110 volts for a total of 220. White is Neutral and ground is Green or bare copper.
Connect the black & blue wire on the ceiling fan to the black wire coming from the wall outlet. Connect the white to the white and green ground to copper ground.
connect black to black wire, connect white to white, and green wire to bracket that came with light,and to bare copper wire that should already be in light junction box.
The colour of copper(II) oxide is black, while that of copper(I) oxide is red. The green colour you see on the Statue of Liberty is because carbon dioxide in the air reacted with the copper to produce copper(II) carbonate, which is greenish-blue.
Copper wiring turns black due to oxidation. It is the air reacting with the metal. Copper wiring also sometimes turns green.
Foolish Fools!, it does infact turn Green! because the oxygen bonds with the copper to form copper oxide, wich is green, it reflects different fractions of light to the copper
Connect the green wire to the brown striped black wire.
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
Pewter turns it black, Copper does turn your skin green though.
when copper carbonate is heated,it changes from a green to a black powder.carbondioxide gas is given off.
copper goes green as it is copper and Oxygen which is Copper Oxide
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.
Remove the old single pole switch. Connect the green dimmer wire to the ground wire. Now connect the black dimmer wire to the black wire that is the hot wire (wire carrying the electrical current into the box). Connect the red dimmer wire to the other black wire.
Connect black to black, red to red, and white to green.
After copper oxidizes it becomes verdigris, or green. Your pipes have just naturally changed color.
connect your black wires to the right side of outlet on the gold screws white wires on the left side silver screws and bare copper wire to green ground screw.
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
lime green, black and yellow
Copper oxide, which is a compound from the two elements copper and oxygen. When copper is exposed to oxygen for a long period of time, it begins turning green. The green is Copper oxide.Copper oxide can refer toCopper(I) oxide (cuprous oxide, Cu2O), a red powder;Copper(II) oxide (cupric oxide, CuO), a black powder. (Source wikipedia)
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
The new cooktop has a 4 wire connection. Red & Black are hot. White is neutral, and green is ground. You existing panel is wired with 3 wires. Black & Red are hot and green is ground. There is no neutral wire. Connect the black to black, red to red, and then connect the white and ground together at the plug.
You get copper (I) oxide which is red and copper (II) oxide that is black. Copper (II) oxide is more stable. In moist air it also forms copper hydroxide and copper carbonate giving the known green color.
