I don't understand the mechanism, can you please describe it for me.The question was "Which one's decomposition temperature is the least among BeCO3, MgCO3 and CaCO3?'

stability of carbonates for Gp IA elements increases as we move down the group bcoz of increase in size.

BeCO3 < MgCO3 < CaCO3

A decomposition reaction is a reaction where a complex molecule breaks down into simpler molecules.

For example, thermal decomposition of potassium chlorate to potassium chloride and oxygen gas.

2KClO3 −→∆ 2KCl + 3O2

arafatjewel2p76n2o: Thank you very much, but my question wasn't that, I asked about the mechanism in the picture.I don't understand the transition of electrons from Oxygen to Carbon!

arafatjewel2p76n2o: In the second line of the mechanism!

AJAYMAHICH: bond break hi to h only

arafatjewel2p76n2o: Okay

arafatjewel2p76n2o: Thanks so lot brother!
