When a copper vessel is exposed to moist air for long, it acquires a dull green coating. The reaction can be represented as
`2Cu+underset("moist air")ubrace(W+X+Y) to Cu(OH)_(2)+Z`
W,X,Y and Z respectively

Text Solution

AI Generated Solution

To solve the problem, we need to identify the components of the reaction when copper (Cu) is exposed to moist air, which leads to the formation of a dull green coating. The reaction can be represented as: \[ 2Cu + W + X + Y \rightarrow Cu(OH)_2 + Z \] ### Step-by-Step Solution: 1. **Identify the Components of Moist Air**: - Moist air consists of water vapor (H₂O), carbon dioxide (CO₂), and oxygen (O₂). Thus, we can denote: ...
