Answer to Question #182354 in General Chemistry for Daniela(me)

Question

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)

Answer 1

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.
