Calcium carbonate decomposes on heating to give calcium oxide and carbon dioxide how much volume of seo2 will be obtained by thermal decomposition of 50 gram of
Answers
CaCO3 decomposition:
CaCO3 -> CaO + CO2
The first thing to do here is to calculate the relative formula mass of CaCO3 and CO2.
RFM of CaCO3 = 40 g + 12 g + (16 g x 3) = 100 g
RFM of CO2 = 12 g + (16 g x 2) = 44 g
The decomposition equation shows 1 CaCO3 goes to 1 CaO and 1 CO2.
We have 50 g of CaCO3, effectively we have half a CaCO3.
50 g / 100 g = 0.5
In order to get the mass of CO2 we need to times the RFM of CO2 by 0.5 (or divide by 2) because of the ratio of CaCO3 to CO2:
44 g x 0.5 = 22 g
22 g of CO2 are obtained from decomposition of 50 g of CaCO3.
