What happens when copper sulphide reacts with oxygen?

Cu2S reacts with oxygen to form SO2: 2 Cu2S + 3 O2 → 2 Cu2O + 2 SO. In the production of copper two thirds of the molten copper sulfide is oxidised as above, and the Cu2O reacts with unoxidised Cu2S to give Cu metal: Cu2S + 2 Cu2O → 6 Cu + SO.

How does copper react with chlorine?

The copper reacts vigorously with the chlorine to form a cloud of copper(II) chloride. When the flask is rinsed with water the copper(II) chloride dissolves forming a blue-green solution. and placed in a flask containing chlorine gas. The reaction forms a cloud of copper(II) chloride.

What happens when copper oxide reacts with oxygen?

When copper and oxygen react to the formation of copper oxide. Copper metal is a red-brown colour, as seen on the outer layer of a penny. Like other metals, it is ductile, malleable and a good conductor of electricity and heat.

What type of reaction is copper II sulfide?

When inorganic substances react, one type of reaction is a single-replacement reaction whereby one element of a substance, such as sulfur in copper(II) sulfide, is replaced by another element, such as oxygen, to form a new molecule, in this example copper(II) oxide and free elemental sulfur.

Does copper sulphate react with oxygen?

Copper sulfide react with oxygen to produce copper oxide and sulfur dioxide. This reaction takes place at a temperature of 300-500. Impurities: – copper sulfate.

What is the balanced equation for SO2 O2 SO3?

What is the balanced equation of SO2 + O2 → SO3? 2SO2 + O2 → 2SO3.

What is the word equation for copper and chlorine?

Cu + Cl2 → CuCl To happen the reaction, copper metal is heated. Copper is a red brown metal.

Why does copper II chloride have a green blue color?

On dilution the colour changes to green and then blue because of successive replacement of chloride ions by water molecules, the final colour being that of the [Cu(H2O)6]2+ ion. The dihydrate can be obtained by crystallizing the solution.

What kind of reaction is copper and oxygen?

combination reaction
Answer – Since Oxygen and Copper combine to form Copper Oxide. Therefore, this is a combination reaction.

What is the chemical equation for the reaction between copper and oxygen?

Copper + oxygen→ copper (II) oxide. Hint: Copper oxide or cupric oxide is the inorganic compound with the formula $CuO$. It is one of the two stable oxides of copper.

What is the chemical name for HgS?

Mercury(II) sulfide
Mercury(II) sulfide, HgS, is a black or red crystalline solid used chiefly as a pigment in paints, rubber, and plastics.

What is the formula for copper II chloride?

CuCl2Copper(II) chloride / Formula

The molecular or chemical formula of Copper(II) Chloride is CuCl2. In its anhydrous form, it appears as a yellowish-brown powder whereas in its dihydrate form it appears as a green crystalline solid.
