Question

how to write the chemical equation of copper carbonate decomposes to form copper oxide and carbon dioxide​

Answer 1

CUco3-->Cuo+co2

This will be the right equation for it

Answer 2

$\bold{\small{\color{orange}{Decomposition\:reaction:}}}$

In this chemical reaction, copper carbonate decomposes to form copper oxide and carbon dioxide as a products. It is a decomposition reaction. It is also known as a single displacement reaction.

$\bold{\small{\color{orange}{Chemical\:Equation:}}}$

$CuCO_3(s) --^{heat}--> CuO(s) + CO_2(g)$

It is a decomposition reaction.

Here, copper carbonate is a reactant and copper oxide and carbon dioxide are products.

Here, copper carbonate and copper oxide both are in solid state, carbon dioxide is in gaseous state.
