Question

CaCO3------>CaO+ CO2 CaCO3 is often used to generate CO2 gas in industry. if 200g of CaCO3 is strongly and 1200 torr pressure.​

Answer 1

Answer:

Correct option is

B

11.2 L

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
