By heating `10 g CaCO_(3), 5.6 g CaO` is formed. What is the weight of `CO_(2)` obtained in this reaction

Explanation

`underset({:(40 + 12 + 16 xx 3),(= 100 g):})(CaCO_(3)) rarr underset({:(40 + 16),(= 56 g):})(CaO) + underset({:(12 + 16 xx 2),(= 44 g):})(CO_(2))`
a. `100 g of CaCO_(3) implies 56 g of CaO`
`10 g of CaCO_(3) implies 5.6 g of CaO`
b. `100 g of CaCO_(3) implies 44 g of CO_(2)`
`10 g of CaCO_(3) implies 4.4 g of CO_(2)`
