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

A

`2.4` g

B

`5.6` g

C

`4.4` g

D

`3.6` g

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(underset(=100g)((40+1216xx3)))(CaCO_(3)) rarr underset(underset(=56 g)(40+16))(CaO) +underset(underset(=44g)((12+16 xx 2))) (CO_(2))`
100 g of `CaCO_(3) rArr` 56 g of CaO
10 g of `Ca CO^(3) rArr 5.6` g of CaO
100 g of `CaCO_(3) rArr` 44 g of `CO_(2)`
10 g of `CaCO_(3) rArr 4.4` g of ` CO_(2)`
