Question

Copper reacts with moist carbon dioxide to give ______?

Answer 1

Moist Carbon dioxide means its state is gaseous.


So, copper reacting with gaseous Carbon dioxide gives copper carbonate.


In the form of a chemical reaction, the equation is Cu (s) + CO2 (g) --- CuCO3 (s).


Balancing the equation gives us: 2 Cu (s) + 3 CO2 (g) --- 2 CuCO3 (s).


This equation would be the balanced form of the given reaction.

Answer 2

Answer ⇒ Copper Carbonate (Blusih Green Salt).

Explanation ⇒  When Copper reacts with the Moist Carbon dioxide, it will form Copper Carbonate which will be  Bluish Green Salt.

Reaction will be,  

 2Cu +  3CO₂ ----------- CuCO₃

To detect it presence, we can easily perform the test for Group 0,1, 2 and so on. By using that, we can detect it presence.  (Test for Cations and test for Anions).
