Explanation:
this is page 119 just sending page 59
last answer is this -:
Solution:
Diamond & graphite are allotropic modifications of carbon.
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
2
& SO_2SO
2
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 and not carbon dioxide is highly poisonous gas.
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.
Carbon monoxide and carbon dioxide are passed through lime water. Carbon monoxide does not turn the lime water milky, while carbon dioxide turns limewater milky.
why not..
