tobby20:

A is very correct

DrSterling:
Please bear with me. My account Nltaliban was banned for the long chain of questions I posted. And the post was also deleted.


However, I won't stop posting.

(a) air pollution

Gracy3535:
But it causes flooding

Bigboy289:
what is the decrease in volume of air when pyrogallol is shaken with 30.00cm3 of air.
A.0.63cm3 .B.0.06cm3 .C.15.00cm3 .D.6.30cm3

what is the decrease in volume of air when pyrogallol is shaken with 30.00cm3 of air.
A.0.63cm3 .B.0.06cm3 .C.15.00cm3 .D.6.30cm3

freshsteph:



C

abeylysis92:

(a) air pollution

abeylysis92:

Alkaline pyrogallol is used to remove oxygen from air since d composition of air is 21% therefore: 21/100*30 equals 6.30cm3

abeylysis92:


not really..Global warming is as a result of d release of poisonous gases into d atmosphere, which pollute d air or so.
