Calcium oxide and oxygen gas are produced by the thermal decomposition of limestone in the reaction caco (s) cao(s) + co (g). what mass of lime can be produced from 4.5 10 kg of limestone? show all the work

As the power on mass of CaCO₃ is not given so we are assuming it 4.5 × 10³ Kg.

             2520 Kg of CaO

Solution:
 
The balance chemical equation is as follow,

                                      CaCO₃    →    CaO  + CO₂

According to equation,

           0.1 Kg (1 mole) CaCO₃ produces  =  0.056 Kg (1 mole)  of CaO
So,
            4.5 × 10³ Kg CaCO₃ will produce  =  X Kg of CaO

Solving for X,
                     X  =  (4.5 × 10³ Kg × 0.056 Kg) ÷ 0.1 Kg

                     X  =  2520 Kg of CaO
