The reaction between copper wire and sulfur. By burying the copper wire with excess sulfur and then heating the mix, the wire becomes completely submerged in...
Reaction between copper wire and sulphur. Copper wire completely reacts with the sulphur to form Copper Sulphide - a compound with comepletely different prop...
Copper outside of the lab. Copper oxidizes easily to form Cu 1+ and Cu 2+ ions. It reacts with oxygen in the air to form brown-black copper oxides, with CO 2 dissolved in rainwater to form green, and sulfur compounds to form copper sulfides.
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.
Non-metals react with oxygen to produce non-metal oxides. For example, sulfur reacts with oxygen to produce sulfur dioxide. The reaction can be represented by this word equation: sulfur +...
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.
In this practical, students add powdered or finely-divided metals to a copper(II) sulfate solution and measure the temperature rises. The experiment reinforces ideas about energy changes during reactions, the reactivity series of the metals and the chemical behaviour of metals.
