9. Quicklime (CaO) is produced by the thermal decomposition of calcium carbonate. Calculate the volume of carbon dioxide at STP produced from the decomposition of 152 g CaCO3. (34.1L)
CaCO3 ---------> CaO + CO2
One mole of CaCO3 gives one mole of CO2
100g of CaCO3 gives 22.4 L of CO2
152 g = 1.52 moles.
Therefore, volume of CO2 produced is 34.05L.
