Question

when 200g of lime stone is strongly heated, it undergoes thermal decomposition to form 112g of lime and unknown mass of carbon dioxide gas as CaCO3 —> CaO+CO2
200g 112g 2

what will be the mass of CO2 formed?
(1) 88g (2) 24g
(3) 64g (4) 40g​

Answer 1

Answer:

1: 88 g

Explanation:

molar mass of CaCO3 = 100g

molar mass of CO2 =44g

100 g CaCO3 produces 44g CO2

200g CaCO3 produces CO2= (44 X 200 ) / 100

so basically ans is 200 g CACO3 produces 88g CO2
