Calcium oxide (CaO; also known as lime) is produced by the thermal decomposition of limestone. When heated, the CaCO3 (limestone) decomposes to form calcium oxide and carbon dioxide. Write a balanced equation for this reaction. What mass of CaO can be produced from 2.00x10² kg of limestone? What mass of CO₂ could be produced?

4. a) Calcium oxide (CaO; also known as lime) is produced by the thermal decomposition
of limestone. When heated, the CaCO3 (limestone) decomposes to form calcium
oxide and carbon dioxide. Write a balanced equation for this reaction. What mass of
CaO can be produced from 2.00x10² kg of limestone? What mass of CO2 could be
produced?
b) The following experimental data were obtained when a mixture of CaCO3 and CaO
was heated in a crucible. Calculate the percent by mass of CaCO3 in the original
sample.
Mass of crucible + sample
Mass of crucible
Mass of crucible + residue (after 1st heating)
Mass of crucible + residue (after 2nd heating)
Mass of crucible residue (after 3rd heating)
