Question

How much Co2 will be produced by the decomposition of 10g CaCo₃ ?
​

Answer 1

Answer:

Wrong, Lavoisier law:”Nothing is lost, nothing is created, everything is transformed”. You don’t create new matter, so the total weight doesn’t change. At the end whatever you do, you will have 10gr of CaCO3,CO2 and CaO.

If you completely convert the CaCO3 (Molecular Mass=100) in CaO (Molecular Mass 56) and CO2 (Molecular Mass 44) you will have

10/100*56=5.6 gr of Ca0 and 10/100*44=4.4 gr of CO2

Answer 2
