Write an equation for the thermal decomposition of CaCO3. Determine the volume of CO2 measured at s t p. that would be produced by the thermal decomposition of 10g of CaCO3. [Ca= 40, O =16 C= 12, molar volume = 22.4dm3 at STP]

Answer : 2.24 L / 2.24 dm³

We need to write a equation for the thermal decomposition of Calcium carbonate . The decomposition is as follows ,

The molecular mass of Calcium carbonate is ,

The reaction is already balanced.

So that,

Hence ,

I hope this helps .

i wish i could but this one is weird give me abc and i can solve it.
