diamond and graphite are allotropic modifications of carbon. Give Reason.
Answers
Answer:
Diamond & graphite are carbon elements, their chemical properties are same i.e. they form CO_2CO
2
on burning but differ in physical state. Hence they are allotropic modifications.
It is dangerous to stand behind a running engine of a vehicle.
A running engine produces carbon monoxide in the form of smoke it releases, which is dangerous for humans.
Both CO_2CO

& SO_2SO

turn lime water milky. Moist potassium permanganate paper helps in distinguishing the two gases.
SO_2SO
2
turns the moist purple potassium permanganate paper to colourless, while CO_2CO
2
gas has no effect on the moist purple permanganate.

Carbon monoxide is considered highly poisonous because it combines with haemoglobin in the blood of a human body. It ultimately decreases the oxygen carrying capacity of blood.
Lime water finds application for testing both carbon dioxide & carbon monoxide gas individually.
