which of the following is one of the cause of charge
Answers
Answer:
When a copper vessel is exposed to moist air for a long time it develops a green layer on its surface. Copper corrodes by oxidation in which it reacts with oxygen in the air to form copper oxide.
Copper oxide then combines with carbon dioxide to make copper carbonate, which gives it a green colour. This process is called corrosion of copper.
The green material is a mixture of copper hydroxide (Cu(OH)2) and copper carbonate (CuCO3). The following is the reaction:
2Cu(s)+H

O(g)+CO

+O

→Cu(OH)

(s)
Copper(II) carbonate is a blue-green compound.
Hence, option B is correct.
Answer:
NA
Step-by-step explanation:
actual transfer ; one material; the other.
The cause of charging a body is due to the transfer of electrons happening in our body. A body can induce charge from a charged body when comes in contact or may be in vicinity. Moving of electrons from one place to another can create a charge thus causing a charge on the body.
