Some Basic Concepts Of Chemistry Question 268
Question: 100 g CaCO3 reacts with 1litre 1 N HCl. On completion of reaction how much weight of $ CO _2 $ will be obtain [Kerala CET 2005]
Options:
A) $ 5.5\ g $
B) $ 11\ g $
C) $ 22\ g $
D) $ 33\ g $
E) $ 44\ g $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \underset{100g}{\mathop{CaCO _3}},+\underset{2N}{\mathop{2HCl}},\to CaCl _2+\underset{44\ g}{\mathop{CO _2}},+H _2O $
100 g $ CaCO _3 $ with 2 N HCl gives 44 g $ CO _2 $
100 g $ CaCO _3 $ with 1 N HCl gives 22 g $ CO _2 $
