1 kwi 2017 · By burying the copper wire with plenty of sulphur and then heating the mix, the wire becomes completely submerged in liquid sulphur. The liquid sulphur then gets to react with the copper, and any oxygen that could possibly oxidise the copper would have to diffuse into the liquid sulphur before reaching the copper.
29 lut 2008 · This demonstration involves some fantastic chemistry and makes an excellent introduction to the use of quantitative calculations to find the formula of a reaction product, copper sulfide. Students will also get the chance to see some of the allotropes of sulfur.
reactions involving copper and sulfur: 1.Formation of Copper(I) Sulfide (Cu2S)-2 Cu + S Cu A 2 S
Why after the sulfur hit the copper was there a delay and the the coil turned red-hot? The heat is coming from the ionic bonds being formed during the synthesis reaction between copper and sulfur. Energy is a bi-product of synthesis reactions and in this case it is released as light and heat.
Procedure. Mix the same amount of sulphur and copper powder in a Petri dish. Fill the mixture 0.5 cm high in a test tube. Carefully heat the test tube with the gas burner. If the mixture starts glowing, stop heating.
In this experiment students study the behavior of copper in sulfur vapor, a piece of sulfur is heated and a picece of copper is held in the vapor in a test tube. The copper and sulfur combine to a new substance, which can be recognized from the change in color, density and other properties.
