thermal decomposition of sodium hydrogen carbonate
2 NaHCO3 (s)-------> Na2CO3 (s) + H2O (l) + CO2 (g)
Above the yield sign is heat because it is thermal decompostion
2 NaHCO3 (s)-------> Na2CO3 (s) + H2O (l) + CO2 (g)
limewater test for carbon dioxide
Ca(OH)2 (aq) + CO3 (g) -------> CaCO3 (s) + H2O (l)
The word equation for the thermal decomposition of calcium carbonate is:
calcium carbonate = calcium oxide + carbon dioxide
this is a reversible change
if you heat them stronger they will form calcium carbonate again!
The general formula for the carbonate of a Group 1 element is M2CO3, therefore
K2CO3 -----> K2O + CO2
The chemical equation is:
RaCO3 = RaO + CO2
Cs2CO3(s) + heat -> Cs2O(s) + CO2(g)
Decomposition of ammonium carbonate:(NH4)2CO3 --> 2 NH3 + CO2 + H2O
Sodium carbonate ---> sodium oxide + carbn diooxide Hoped this helped (:
CaCO3 (s) -----> CaO (s) + CO2 (g)
MAGNESIUM OXIDE + CARBON DIOXIDE Mg + CO2
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
Decomposition of ammonium carbonate:(NH4)2CO3 --> 2 NH3 + CO2 + H2O
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.
A-----------B + C
The thermal decomposition of sodium carbonate is a chemical reaction according to the equation: Na2CO3 -> Na2O + CO2. The reaction is endothermic and therefore proceeds rapidly in the direction shown only in an environment from which ample heat energy can be absorbed.
Sodium carbonate ---> sodium oxide + carbn diooxide Hoped this helped (:
CaCO3 (s) -----> CaO (s) + CO2 (g)
MAGNESIUM OXIDE + CARBON DIOXIDE Mg + CO2
This is a thermal decomposition reaction.
basically you just need to use your brain to answer this question
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
The chemical equation is:SiH4 = Si + 2 H2
At high temperature, limestone undergoes thermal decomposition. The word equation is calcium carbonate decomposes when heated to calcium oxide and carbon dioxide. The chemical equation is CaCO3 + heat --> CaO + CO2.
