Answer:

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

2

at STP.

Describe the difference between a reaction that occurs spontaneously and one that does not
lidiya [134]
2.B. Describe the difference between a reaction that occurs spontaneously and one that does not.
