Some Basic Concepts Of Chemistry Question 24

Question: Assuming fully decomposed, the volume of $C O_{2}$ released at STP on heating 9.85 g of $B a C O_{3}$ (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] $B a C O_{3} \overset{}{\to} B a O + C O_{2}$ 192 g of $B a C O_{3}$ gives 1 mol of $C O_{2} = 22.4 L$ 9.85 g of $B a C O_{3}$ will give 0.05 mol of $C O_{2}$ which is equal to 1.12 litre.
