Question

Xg calicium corbonate gives 28g calicium oxide and Yg corbon dioxide on heating according to low of conservation of mass x and y will be respectivaely​

Answer 1

Answer:

11.2 L CO

2 at STP

Explanation:

Chemical reaction involved is

CaCO

3

→CaO+CO

2

Molar mass of CaCO

3

=40+12+16×3=100 g

According to the balanced reaction 100 g of CaCO

3

produces 1 mol of CO

2

i.e. 22.4 L at STP.

∴50 g CaCO

3

will produce

100

22.4

×50=11.2 L CO
