carbon dioxide
[CuCO3 --> CuO + CO2]
carbon dioxide is produced when it is heated
Endothermic because thermal decomposition is the breakdown of a compound using heat. Remember endo means more energy is taken in breaking the bonds of copper carbonate than there is given out when making the bonds of copper oxide and carbon dioxide.
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
It decomposes into calcium oxide and carbon dioxide...
Copper (Cu) + Chlorine (Cl) -> Copper (I) Chloride (CuCl)
Carbon dioxide is released.
carbon dioxide is produced when it is heated
carbon dioxide, when carbonates are heated carbon dioxide is is given off.
Carbon Dioxide is given off. (CO2)

copper (II) carbonate is a solid
The gas is Carbon dioxide, formed by the decomposition of Calcium carbonate it the Marble or Limestone
nitrogen
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
Explanation: Copper(II) carbonate (solid), when heated, forms copper(II)oxide (solid) and carbon dioxide (gas). First, the formation of a gas is one hit this is a chemical change. The second hint, the chemical reaction cannot be reversed.
it is broken down by heating. once it is being heated, some greenish yellow gas will be given out. i believe that 'gas' is chloride. :)
As the volume of a given gas sample is dependent on its temperature and pressure; to find a volume of any gas which does exist, the temperature and the pressure of the system/vessel should be given directly or could be calculated.
