CaCO3 heat CaO+ Co2 liberated
from the above equation calculate the amount of carbon dioxide in grams liberated by heating 25g of calcium carbonate
 

CaCO3    CaO  +  CO21 mole                          1 mole100g                               44 g100 g of CaCO3 produces 44g of CO2So, 1g of CaCO3 produces=44100g of CO2Therefore, amount of CO2 liberated by 25g of CaCO3= 44100×25=11gHence, 11g of CO2 is produced by 25g of CaCO3
