The equation is different for each compound.
As general: A = B +D
Iron is an element and does not decompose. However, it can melt so Fes + HEAT = Fel
Decompostion is to break down a substane.For example you can decompose a scientific equation.
Effects are: boiling or thermal decompostion.
A-----------B + C
The chemical equation for the thermal decomposition of lead nitrate is: 2Pb(NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g)
Decomposition Reaction
The chemical equation is:SiH4 = Si + 2 H2
This is a thermal decomposition reaction.
Na2SO4.7H2O----------------Na2O + SO3 + 7 H2O
Decomposition of ammonium carbonate:(NH4)2CO3 --> 2 NH3 + CO2 + H2O
One; for example the thermal decomposition of a compound.
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)
