Some Basic Concepts Of Chemistry Question 24
Question: Assuming fully decomposed, the volume of $ CO _2 $ released at STP on heating 9.85 g of $ BaCO _3 $ (Atomic mass, Ba = 137) will be
Options:
A) 1.12L
B) 2.24L
C) 4.06L
D) 0.84L
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ BaCO _3\xrightarrow{{}}BaO+CO _2 $ 192 g of $ BaCO _3 $ gives 1 mol of $ CO _2=22.4L $ 9.85 g of $ BaCO _3 $ will give 0.05 mol of $ CO _2 $ which is equal to 1.12 litre.
