1: Find mass of calcium oxide formed when 200g
of calcium carbonate is heated ?What amount of carbon dioxide is released during this process??
Please answer correctly and fast​

Answer 1

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.

Answer 2

Answer:

Thus the answer is 11.2 L.
