The correct order of increasing thermal stability of K2CO3,MgCO3,CaCO3 and BeCO3
The correct order of increasing thermal stability of K2CO3,MgCO3,CaCO3 and BeCO3



BeCO3 < MgCO3 < CaCO3 < K2CO3
As given in NCERT he stability of carbonates for Gp IA elements increases as we move down the group bcoz of increase in size
