Question

If 100 gm of limestone is heated, volume of CO2 formed at N.T.P. is A.11.2 litres B.22.4 litres C.5.4 litres D.1 litre

Answer 1

Answer:

B 22.4 litres

Explanation:

equation  CACO3----------> CAO + co2

given that caco3 is 100 gram it means 1 mole    (moles=given wt/ molecular wt)

according to the equation 1mole caco3 produces 1mole co2

so amount of co2  is 1 mole or 22.4 litres           (1mole= 22.4 litres at NTP)

(NOTE  ACTUALLY AT NTP VOLUME MOF ONE MOLE IS 22.7 LITRES )

Answer 2

The volume in litres of CO2 liberated at STP, when 10 g of 90% pure limestone is heated completely.
