No, CuCO3, or copper carbonate is a compound made up of an element and a polyatomic ion.
12.5 (g CuCO3) = [12.5 (g CuCO3) / 123.555 (g/mol CuCO3)] = 0.1012 (mol CuCO3)0.1012 (mol CuCO3)* [1 (mol CuO) / (mol CuCO3)] = 0.1012 (mol CuO)= [0.1012 (mol CuO) * 79.545 (g/mol CuO)] = 8.047 g CuO = 8.05 g CuO
Yes, that is correct. When copper carbonate (CuCO3) is heated, it decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
This is not a decomposition reaction.
Yes, NaCH3COO (sodium acetate) is soluble in water as are all sodium compounds.
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
There are 11 atoms in one molecule of CuCO3. This includes one copper atom (Cu), one carbon atom (C), and three oxygen atoms (O) in the carbonate ion (CO3).
There is one atom of carbon in this formula. The formula indicates one atom of Copper + one atom of Carbon + 3 atoms of oxygen. O3 added to any compound prompts the suffix -ate, so in this case, you have a formula for Copper Carbonate.
In copper carbonate (CuCO3), the carbonate ion (CO3^2-) is a covalently bonded polyatomic ion. The copper atom is not part of the polyatomic ion in this compound and is ionically bonded to the carbonate ion.

The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
Copper carbonate is a chemical substance, also called Cupric carbonate. The molecular formula is CuCO3. Copper carbonate decomposes at high temperatures, giving off carbon dioxide and leaving copper(II) oxide.
12.5 (g CuCO3) = [12.5 (g CuCO3) / 123.555 (g/mol CuCO3)] = 0.1012 (mol CuCO3)0.1012 (mol CuCO3)* [1 (mol CuO) / (mol CuCO3)] = 0.1012 (mol CuO)= [0.1012 (mol CuO) * 79.545 (g/mol CuO)] = 8.047 g CuO = 8.05 g CuO
CuCO3 ---> CO2 + CuO which is copper oxide

CuCO3
Copper carbonate (CuCO3) consists of one copper atom (Cu), one carbon atom (C), and three oxygen atoms (O) per molecule. Therefore, there are a total of five atoms in one molecule of copper carbonate.
The corresponding ionic reaction would be; Cu2+(aq) + CO32-(aq) -> CuCO3(s)
