Calcium carbonate, $CaCO3\text{CaCO}_3$ , decomposes on heating to produce calcium oxide, $CaO\text{CaO}$ , and carbon dioxide, $CO2\text{CO}_2$ .

\text{CaCO}_3 \longrightarrow \text{CaO} + \text{CO}_2

What is the atom economy for the production of calcium oxide ( $CaO\text{CaO}$ ) in this reaction?

( $M_r$ : $CaCO3=100\text{CaCO}_3 = 100$ , $CaO=56\text{CaO} = 56$ , $CO2=44\text{CO}_2 = 44$ )

$44%44\%$

$56%56\%$

$78%78\%$

$100%100\%$
