How is copper carbonate decomposed?

Answer 1

#CuCO_3(s) + Deltararr CuO(s) + CO_2(g)uarr#

As previously mentioned, carbonates break down when heated to produce metal oxide and carbon dioxide; the mass is lost as carbon dioxide. The mass loss as carbon dioxide can be calculated using the masses of calcium carbonate and its residue both before and after the breakdown reaction.

Occasionally, the reaction's effluent gas is forced to bubble through a calcium hydroxide solution, causing the carbon dioxide to turn milky as calcium carbonate precipitates:

#CO_2(g) + Ca(OH)_2(aq) rarr CaCO_3(s)darr + H_2O(aq)#

When heated, copper carbonate breaks down into carbon dioxide gas and copper oxide, with the following chemical equation describing the reaction: CuCO3(s) -> CuO(s) + CO2(g)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
