Calcium carbonate decomposes according to the following equation:
Bad White [126]

Answer:

CaCO3----------CaO+CO2

(40g+12g+16g×3) of CaCO3 produce (40g+16g) of CaO

100g of CaCO3 -----------------56g of CaO

20g of CaCO3-------------------x grams of CaO

x=(20g×56g)÷100g

x=1120gg÷100g

x=11.2g of CaO

Therefore, 11.2grams of CaO from 20grams of CaCO3
