Eben331:
I forgot to subtract also, thanks for pointing that out. So this question was set last year? Truly, UI questions are technical. Pls post more of it. Is the answer to the question 2 or 14 OR 2 to 14. I am just curious to knw the right ans.

Since the least resultant is 2 and the highest is 14, the answer is 2-14


You can see 2 or 14 in the options sha

*CHEMISTRY TIPS*
1. The most reactive metal known is Francium .

2. GEL is a SOL which contains more solid particle dispersed in liquid than usual.

3. The hardest substance known to man is DIAMOND .

4. The lowest Oxidation State of IRON is ZERO

30.5505g[/quote,)

I calculated it as well
got 3.06g
u might recheck it

Myketuale:
please somebody should help me out what weight of HCL is present in 155ml of a 0.540 solution?? thanks

155*0.540*36.5/1000 gives 3.055g
please, I'm open to corrections

Bigboy289:
The concave shape of a bird's wing during flight, ensures that the greater air pressure under the wings will : A.counteract the effect of gravity. B.lift the bird so that it can remain airborne. C.enable the pectoral muscles to contract easily. D.change the direction of the flying bird. ??

tobby20:

A is very correct

The answer should be B.
Study this http://birds.ecoport.org/Identification/EBflight-shape.htm

yeah eben....
3.06g is correct

conversion ish.....

yes, you're right

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


However, I won't stop posting.


Operation crush ui

Why is Nairaland doing like this na. That is how I was also banned from sending pm via Nairaland.

okay boss
noted. thanks

But it causes flooding

abeylysis92:

(a) air pollution

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

Gracy3535:
But it causes flooding

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

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

21/100 × 30 =630/100=6.30cm³


D

C

A.0.63cm3 .B.0.06cm3 .C.15.00cm3 .D.6.30cm3

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

freshsteph:



C

please explain boss
thought it's air pollution
I wanna learn, sir
I thought global warming involves d release of poisonous gases like co2, so2, CFC into d atmosphere
and some of these gases reduces d level of ozone in d atmosphere, which help to absorb and reduce d UV rays reaching s earth, but since it has now been reduced, the amount of UV reaching d earth will increase..

abeylysis92:

(a) air pollution

the answer is (d) flooding

D

Bigboy289:
D

yeah you are right it is flooding as a result of constant climatic changes noted boss
