CuCO3 --> CO2 + CuO (gas + black powder)
Further heating may result in :
CuO --> 2Cu + O2 (metal copper + gas)
CuSO4 · 5H20 = 5H2O + CuSO4
when blue Copper sulphate is heated, it loses its water part of crystallisation and tuns into white, anhydrous copper sulphate crystal
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.
There is no reaction at all.
The iron will displace the copper as it is more reactive. here's the equation: iron + copper sulphate = iron sulphate +copper
The formula for iron is Fe. The formula for copper sulfate is CuSO4. The chemical equation for the reaction is Fe (s) + CuSO4 (aq) --------- Cu (s) + FeSO4(aq) The iron is a more active metal than copper therefore it replaces the copper in the copper sulfate solution.
Thermal decomposition and loss of water are chemical changes.
CuSO4•5H2O + heat ---> CuSO4 + 5H2O
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
There is a balanced equation to use for decomposition of copper II sulfate pentahydrate. It is the following: CuSO4.5H2O+heat -->CuSO4(anhydrous)+5H2O.
This equation is CuSO4.5 H2O -> CuSO4 + 5 H2O.
Copper Nitrate
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
when blue Copper sulphate is heated, it loses its water part of crystallisation and tuns into white, anhydrous copper sulphate crystal
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
The chemical decomposition is:CuSO4------ CuO + SO3
in English it is basically breaking something down using heat --------------- Thermal decomposition is a chemical reaction of decomposition under the effect of high temperature: the compound breaks down into other substances when it is heated. For example: copper(II) sulfide when heated produces copper + sulfur dioxide
The chemical equation is:Zn + CuSO4 = ZnSO4 + Cu
