No, that's a "choke", or if there are two coils, it's a transformer.
A capacitor is two "plates" (in reality they are usually just foil) that are connected to two wires. Often (typically) there is an electrolytic between the plates.
There is more to a capacitor, but that's the basics.
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.
