1.	Q23. What happens when a copper vessel is exposed to moist for long time? Write wordequation of the reaction.
Answer» Answer: Copper is comparatively less REACTIVE but reacts with reagents like oxygen and water in ATMOSPHERE in a slow time. Also carbon dioxide helps in the reaction. As it is a metal, it will start corroding $.$ After some days, we will observe greenish layer on the surface of copper vessel due to the formation of copper carbonate. The required reaction is: Copper when reacts with carbon dioxide, water and oxygen forms basic copper carbonate. ${ \boxed{ \rm{2Cu + CO_2 + O_2 + H_2O \longrightarrow CuCO_3.Cu_(OH)_2}}}$ The basic carbonate is a green coloured SUBSTANCE formed due time. Another example is the statue of LIBERTY in New YORK, USA.
