Ahmadjr:

Buh na wa for you oo. You just make tempers dey flare for one thread.. me maa being don vex die.

I guess that's just luv for chemistry

Naxo ma broda!

Good but why sire?

Teaching will commence on october for now i will drop sometin to kip u guys busy, sometin dat will make u guys to tink hard

CHEMISTRY

calculate d oxidation number of nitrogen in NO3-

physics
what is d unit for luminions intensity called?

Oxidation number of N is 5
NO3-
N(-2)3 =-1 (valency of Oxygen=2)
N(-6) =-1
N=-1+6
N= +5

Benjaminbest: If u no that u will be writing jamb or postume please let us hook up here.these thread is created to prepare student for early preparation for d exams mentioned above.here u will be taught the following subject
English language
Biology
chemistry
physics
maths
economics
commerce
crs
agric
geography
including other subject dat are not listed above





we will also test ourselves on past questions relating to the subjects mentioned. So if u have any interest about this please hit the like button or comment by bringing more ideas. So if u have any question please dont be ashame to ask. Wish you all the very best.










Teaching starts tommorrow. Art student are also welcome to join the thread be sure to get what u want from God because he is d great teacher. Alright guys blaze up for tommorrow class.. Time...10:00am prompt

You've done well but don't you think learning will be at a slow rate and also limited when three departments and combined together. It'll bring confusion. That was why a thread for Eng/lit, govt/crs was created for jambites by fynestboi.

LIMUMINOUS FLUX IS LUMEN ND LUMINOUS IMTENSITY IS CANDELA

Halpher:
Good but why sire?

dispropornation reaction is a form of redox reaction exhibited by a specie.
When dissociate thus;
H202 --> H20 + 02
the o.n of Oxygen changes from -1/2 in H202 to -2 in H20(reduction) and from -1/2 in H202 to 0 in 02(oxidation).

PHYSICS: WHAT ARE THE UNITS F MAGNETIC FLUX ND MAGNETIC FLUX DENSITY??

chimhigher: LIMUMINOUS FLUX IS LUMEN ND LUMINOUS IMTENSITY IS CANDELA

chimhigher: LIMUMINOUS FLUX IS LUMEN ND LUMINOUS IMTENSITY IS CANDELA

kudos bro i must admit u are gud....but dont forget u left one unattempted

Disproportionation
Good! But BaO2 is also a peroxide?

chimhigher: PHYSICS: WHAT ARE THE UNITS F MAGNETIC FLUX ND MAGNETIC FLUX DENSITY??

Weber and Tesla respectively while that of luminous intensity is candela

chimhigher: PHYSICS: WHAT ARE THE UNITS F MAGNETIC FLUX ND MAGNETIC FLUX DENSITY??

The Unit are:-
Weber and weber per metre square Or Telsa.Respectively.

CHEMISTRY....1.When Uranium 235 disintegrates,If it releases 2 beta particles) nd an alpha particle,WHAT WILL B D MASS ND ATOMIC NUMBER OF D PRODUCT...




PHYSICS:: A MAN Near a Cliff CLAPPED 5 TIMES ND Heard Dem Echoes 10 SECS LATER..CALCULATE D VELOCITY,IF D MAN ND D CLIFF IS 45M DISTANCE..




MATHS: DIFFFERENTIATE Y=AX+B...IN RESPECT TO X..GIVEN DAT A and B Are constant

chimhigher: PHYSICS: WHAT ARE THE UNITS F MAGNETIC FLUX ND MAGNETIC FLUX DENSITY??

d unit for magnetic flux is weber

Benjaminbest: d unit for magnetic flux is weber

Yah U Right....

Benjaminbest: Am kind of very busy at work right now....am not encourage with what am reading i have an ebook that contain d top secret of jamb but because of security purpose i will release d content on new yr day......so guys i will advice u to read hard because jamb is taking a different route next year......lets not study to pass lets study to break d record beyond repair. Tanks guys i will release d lecture time table today

I will be glad if u kindly forward that ebook to my mail-kunlex4real95@gmail.com...thanks in advance

u only gave d mass number atomic number is not there.........d mass number will decrease by four and fall into 231 why d atomic number will remain costant as a result of d beta particle away from d apha particle

Incredyable: During my jamb days, I used New school(Ababio) for chemistry nd i didn't see it anywhere that water is hygroscopic.
I had the privilege to read a friends chemistry jotter, nd i saw in it that water is hygroscopic. I was shocked wen i saw it. on asking him,he told me he saw it in lamlad's chemistry. I had no choice but to accept ..
dats y i said halpher myt be ryt.
different text books give different examples.

did u see it in d textbook urself? To me i strongly believe dat seeing is believing

JSMMUYIWA:
@FASADECAPO YOU BROUGHT ME HERE.
BUT AS I DEY SEE AM SO,A LOT OF FELLOWS HAVE PROOF ELUCIDATELY AND HAVE BEEN RIGHT IN THEIR VIEW ON WATER BEEN NOT HYGROSCOPIC.
And like most guys have said hygroscopic substance coid turn sticky on absorption of air moisture increasing in volume,could at the same time become diluted if in solution form of a particular concentration on absorption of water(or u call it moisture).
MEANWHILE I HAVE A QUESTION FOR THOSE SAYING WATER IS HYGROSCOPIC:
What criteria cud a substance be diluted(is it not by water?)
A pure water wouldn't increase in volume when in open air except if impure (as in solution e.g H2SO4)
The only thing that can cause pure water to increase in volume is thermal energy(heat) or its abnormal change in density(below4°C)
SAVE OR EXCEPT YHIS THE WATER IS IMPURE(ETHANOL,SULPHURIC ACID E.T.C)

clap 4 dis guy wella, 20 bottle of odeku 2 dis guy joor!
