Some Basic Concepts Of Chemistry Question 257
Question: On electrical decomposition of 150 ml dry and pure $ O _2 $ , 10% of $ O _2 $ gets changed to O, then the volume of gaseous mixture after reaction and volume of remaining gas left after passing in turpentine oil will be
Options:
A) 145 ml
B) 149 ml
C) 128 ml
D) 125 ml
Show Answer
Answer:
Correct Answer: A
Solution:
$ \because $ 3ml (O) $ \to $ 1ml $ O _3 $
30ml (O) $ \to $ 10ml $ O _3 $
$ x=\frac{150\times 10}{100}=15ml $
V of $ O _2+ $ V of $ O _3=135+10=145ml $
Turpentine oil absorb ozone.
