Copper is a chemical element, and is occasionally found as the native metal. Most commonly it is found combined with sulfur, or other natural acid groups. These are generally derived from fluid flow from volcanic sources, and much of our copper is of this origin. As a relatively heavy metal, it will migrate towards the core of the earth, but the hot liquid solutions associated with vulcanism may bring it to the surface.
When copper is heated in oxygen, the compound formed is copper oxide.
When copper reacts with curd, no new products are formed, as curd does not have any specific chemical reaction with copper. However, the acidic nature of curd may cause the copper to corrode or tarnish, forming a greenish layer of copper carbonate or copper hydroxide on the surface of the copper.
When copper reacts with chlorine, copper chloride is formed. The balanced chemical equation for the reaction is: 2 Cu + Cl₂ → 2 CuCl
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
When copper is burned in the presence of air, it forms copper oxide. Copper oxide can exist in different forms, such as copper(I) oxide (Cu2O) or copper(II) oxide (CuO), depending on the conditions of the reaction.
Copper sulfide is the compound formed when copper reacts with sulfur. Depending on the ratio of copper to sulfur, different forms of copper sulfide can be formed, such as Cu2S and CuS.
When copper is heated in oxygen, the compound formed is copper oxide.
When copper is heated, it undergoes oxidation and forms copper oxide as the main product. If the heating is carried out in the presence of oxygen, copper oxide (CuO) is formed. If the oxygen is limited, copper(I) oxide (Cu2O) can also be formed.
When copper is mixed with oxygen, copper oxide is formed. The specific compound formed depends on the ratio of copper to oxygen present during the reaction.
On the copper surface basic copper carbonate is formed.
The black substance formed on copper is called copper oxide. It is a chemical compound that forms when copper is exposed to oxygen in the air, resulting in a black or greenish-black tarnish on the surface of the copper.
lead chloride is formed
Copper sulfate is formed.
When copper reacts with sulphuric acid, copper sulfate is formed. This reaction involves the displacement of hydrogen in sulphuric acid by copper, resulting in the formation of copper sulfate and hydrogen gas.
with water aswell it would become copper carbonate
The two forms of copper are copper(I) and copper(II). Copper(I) is formed when copper loses one electron, while copper(II) is formed when copper loses two electrons. Copper(I) is typically bonded with elements such as chlorine or iodine, while copper(II) is commonly bonded with elements like oxygen or sulfur.
