Question

how to prove CaCO3 gives CaO + CO2 is not a Redox reaction

Answer 1

In CaCo3

gives us compounds as follows:

calciumoxide
carbon dioxide

here in product we have 3 oxygen molecules and if we count in sum too there are 3 oxygen molecules one in calciumoxide and 2 in carbon dioxide so here we can say there is no loss in oxygen compound.

in redox reaction oxygen molecules are lost and hydrogen molecules are gained but here is no loss and gain of oxygen and hydrogen.


so we can say that it is not a redox reaction.
