there is still more should it proceed?

Yes o

guy you uncountable much, keep it up

but guys just make sure ur mouth are short oooooo! keep it to ur self and to ur fellow gurus only, because if there is too much noise on it, them may cancel it ooooooooooooo!
am still waiting for request

but d way am also doing d exam too, and is only practicals that i have, so what about theory... admin we need ur help! and guys if u have any thing just drop sharply

I believe when the time for theory comes Ashawo will help you out because he said that he works there.

yes o...this site is the best,but i hope u guys are gonna help us during theory period..thankz

You guys are jst too much. Thanks alot.

guy u 3much abeg i want d full practical question on chemistry abeg so i go prepare wit it,thank olenu!

Guys just add me on 2go by username paul4love and get d latest questions....DIS SITE IS GUD BUT WAEC AGENTS ARE HERE

U mean it?

pls i need chemistry pratical question,if any pls send it to dis email address dayomark4life@yahoo.com pls am graetful

guys....
help me please; with chemistry practical questions if there is any...you can mail it to this email:fwang42@gmail.com
THANKZ

abeg @paul4luv abeg am nt sighnd on 2go send me d questns tru facebuk search me tru ma email:prinze_edet92@yahoo.com or beta stil jst email me al d practical questns on chem,bio and physics i ll sort d answers ma self. Thanks d sky is d limit 4 u.

see guy dat 2go is for phones only; and by wayif waec agent are in disd site there own cup of tea just drop ur threat and put smile on ur fellow gurus fsce and for move on
'no skin pain' d deal day is friday so weak up oooooooo!











'

paul4luv u knw av neva been 2 d 2go website al i ask now is 4 u 2 send me d site link of the 2go website so i can contact u pls,am DESPIRATE.

guys...
Please help me with chemistry practical.. I mean the raw question.

I'll advise everything should be done here n not 2go

Drop the stuff here instead of going too far

Na waoh

If we win tonight i will post it but we loose..... Na una sabi

ahhhhhhh Ashawo no be so oh guyz are in dyin need of dis tin help dem

Ashawo if u are man u fan just know we have already won if not na u sabi ooooooo.

i have chemistry now but some can't attach some thing in dis site, i could just scan it and attach it. let us just pray dat ashawo and his team wins the march so dat he can post his own.

up man u.i am very sure we are going 2 win d champions league.dont forget 2 drop d bomb

ashawo pls man u won if u re man u fan pls rite it 4 us wil nid it

up Man U; Man U for live; ashaow start spilling

i have got everything about chemistry practical...these a tip of it........


A is a solution of HCl acid. B contains
5.8gdm-3 of potassium Hydroxide
(KOH)
solution
a) put A into d biurrete and titrate it
against
20.00cm-3 or 25.00cm-3 portion of B
using
methyl orange as indicator. Record
the
volume of ur pipette. Tabulate ur
biurette....
MORE IS YET TO COME BY 4PM TODAY..

more is yet to come by 4pm today...so stay tight on site.!

Sorry na beer cuz am o, Emma thx for helping me out

see guy the main important is the number three(3) question.

are u guy read?

- C is a mixture of 2 simple inorganic salts. Carry out the following test on C. Record your observation and identify any gases evolved. State the conclusion you draw from the result of each test. (A)Put all C in a test tube,add about 10cm3 of distilled water stir,filter and keep the residue. (B)Put the residue into a test tube,add about 5cm of dilute Hcl acid. Shake to dissolve. (Bi)To about 2cm3 of the solution,add NaoH(aq) in drops and in excesses. (Bii)To another 2cm3 of portion of the solution,add aqeous ammonia in drops then in excesses (Ci)To about 2cm3 portion of the filterate,add few drops of dilute HNo3 acid then 1cm3 of AgNo3 solution. (Cii)To the mixture in ci) above,add aqeous ammonia in excess............................

part B is coming soon; pray so i can remember to post it here.

why can't we for once forget about dropping emails?

NO PHYSICS...............

Oga john bull,ability n evrybody,though we hav read but pls help us.

Quantitative analysis,reactant,Hno3,bacl,dilute hcl,naoh,nh3,lime water...NOTE: In your exam,zinc and co3 is confirmed

PART B
>>A is a solution of HCl acid. B
contains
5.8gdm-3 of potassium
Hydroxide (KOH)
solution
a) put A into d burrete and
titrate it against
20.00cm-3 or 25.00cm-3
portion of B using
methyl orange as indicator.
Record the
volume of ur pipette. Tabulate
ur burette
readings and calc. d average
volume of A
used
the equation of the reaction is:
HCl(aq) KOH(aq)=KCl(aq) H2o
(i)
b) from ur result and info
provided cal
i. concentration of B in
moldm-3
ii. molar concentration of A in
moldm-3
[H=1,O=16,K=39]
>>A is a solution cointaing
0.103ldm-3 HX. B is
a solution cointaning 5.6gdm-3
of KOHL
a) put A into the burette and
titrate it
against 20.00cm-3 or
25.00cm-3 portion of
B using methyl orange as
indicator. Record
the vol of ur pipette. Tabulate
ur burette
readings and calc. the average
vol of A used
the equation of the reaction is:
HCl(aq)+KOH(aq)=KCl(aq)
+H2o(l)
From ur result and info
provided calc.
i. concentration of B in

5.6moldm-3 of XOH solution,
put A into d burette and titrate
it against 20.00cm3 or
25.00cm3 portions of B using

Record d vol of ur pipette.
Tabulate ur burette reading
and calculate d average vol of A
used. The equqtion for the
reaction is: XOH(aq)+HCl(aq)
=XCl(aq)+H2o(l) From ur
result,........

i have not seen the number 3 question. so i have done my part

menh u quit funny.............. any way u are welcome

My sis said it clicked. Nice work pal. Hopin 2 ask if u'll pest physics

coming soon; just pray i remember it.

the guy that called me today pls just help to drop ur email id; i want to give u biology question and answer..special
