burning copper wire reaction

  • The effects causing the burning of plastic coatings of

    The copper conduit broke before the plastics would burn (in the case of specimens 2 and 3). However an oversized copper conduit could also be a source of fire hazard because it can still conduct current when glowing even without a sheath (in the case of specimen 5). Unfortunately it could be forecasted because of the low LOI value.

  • reaction mechanismHeating copper wire and sulfur

    1 Answer1. Active Oldest Votes. 3. By burying the copper wire with plenty of sulfur and then heating the mix the wire becomes completely submerged in liquid sulfur. The liquid sulfur then gets to react with the copper and any oxygen that could possibly oxidize the copper would have to diffuse into the liquid sulfur before reaching the copper.

  • the reaction of copper wire and a flameChemistry

    Copper may be somewhat oxidized at its surface but it hardly can be called a reaction. You will get copper (I) oxide and copper (II) oxide in a very thin layer around the copper metal. The inside does not react. The flame can also reduce some of the oxide back to copper. The hot gas is
