2. Pb(Cr2O7)2 + Na3Po4 ---> Na2Cr2O7 + Pb3(PO4)4
Carbonate (CO3-2) ion mostly decomposes to carbon dioxide.
As you can see in the decomposition of sodium carbonate i.e. Na2CO3 -> Na2O + CO2
In decomposition reaction of carbonate ion; the oxidation number of carbon atom in carbonate ion and carbon dioxide are the ...
The solution gives the specific answers by using a general method described to balance equations.
