Oh,thks 4ur observatn,itz a graphicl error.l=1 instead ov zero

larri: d question is incorect i tink d ans is a. Na since l=0 it means it is s subshell and it suppose 2 av m=0 m=3 refers 2 p orbital with
l=1
s=0(azimutal quantum l)
p=1 (azimutal quantum l)
d=2(azimutal quantum l)
f=3(azimutal quantum l)
remember m=-l,0l

s=0 (magnetic =1)
p=-1,0,1(magnetic no =3)
d= -2,-1,0,1,2(magnetic =5)

so l=0 can not av m=3 quantum number since l= 0 means s orbital also since p orbitals only av m=3

Yeah u r rite,bt i stil av lotz to do.may God See us tru!

ANDREW2EIC: I have been around my guy, but didn't know the existence of this thread. I just found it yesterday. Anyways, how is jacking going over there? The D day is almost close

Which of the follown atoms has the follwn,n=3,l=0,m=3orbitals,s=+1/2 or -1/2?a.Na b.Ne c.Al d.Si

Yeah,whr av u bn snce?u r 2correct!

ANDREW2EIC: My real guy nice to meet u here.
The answer to ur question is c).
Reason: the power of the accelerated car = energy expended by the car/time taken.
But in this case, the energy of the car is all kinetic.
Hence, power(P) = k.e/time(T), P = 1/2MV^2/T. Multiplying both sides by T.
PxT = 1/2MV^2/TxT, PT = 1/2MV^2. Divide both sides by P.
PT/P = 1/2MV^2/P,
Therefore, T = MV^2/2P.

I bliev wit prayer nd hardwork one cn stnd a chance!

There is! Jxt start last yr like neva b4,da new Vc z an indigen so he admittd mostly indigenz,frm edo stat i mean

korm2me: it was 66 last yr, 65 last 2 yrs. No special prefrence 4 indigen. Am in medicine. U kan ask wat u wana knw

Gr8t ife,i trust una...na ife guyz dae blast jmb pass!mm,lovly

Plz jxt read as if u r gonna b made da presido of naija wif gr8t jamb score.NEVA TIRE BRO,remain smal.

I cn see sum1 önline,plz dnt go widout leaving a questn

Yeah,sam as C i only twstd it!

t.boy007:
i think CaF reduces the melting point during extraction of Ca

Only argn z used to prvnt oxidatn,nt mxture of argn nd nitrogn

t.boy007:
i think there are two answers there,1=it prevent oxidation in filament lamp and then prevent blackening.but it seems both have thesame meaning chemicaly

Sum1 try ds,A Car of mass Mkg is accelratd uniformly frm rest by an engine power P.The minimum time it wil take to attain a speed V is,a.MV/P b.MV/2P c.MV^2/2P d.MV^2/P

Ansa z A,cuz evry memba in da group hz an electrn in outa shell wich z responsible 4their reactivity likewis weak metallic bond

t.boy007:
it's soft,(property of group 1 metal)

B

mayorall: Which of the following will undergo substitution reaction?

A. C4H8
B. C7H16
C. C2H4
D. C8H16

Scarcodina,bt itz subphyllum nau...2 remind u,brng jamb questns!

mayorall: Amoeba belong to which of the following phylum?.

A. Mastigophora
B. Sarcomastigophora
C. Sarcodina
D. Ciliophora

z there anytn lyk dat B?ur ansa C

Ansa,A

mayorall: Yeah..buh there are two

Chck da questn vry well,ansa z there

mayorall: Both legumes and capsules separate divided part contains seeds...the only dfrnc z dat d earlier z made frm dfrnt carpels.....

The type of dehiscent fruit in which each separat divided part contains a seed is,a.schizocarp b.follicle c.capsules d. Legumes

Sodium metal is easier to cut with a knife than a calcium metal bcus,a.its found in group 1 b.its nt totally considered as metal c.its soft d. its crystals r planar in shape

GUD!Am also chalengd to brng more questnz'I AM QUITE CHALLENGED WIT UR QUESTIONS AND ANSAS HERE'

Right!i use any txt bro 4both,bt mainly college for bio

sagaciousblog: the ansa is C becos it lowers the melting point...WHICH TXTBOOK DO U USE FOR BIO AND CHEM?I AM QUITE CHALLENGED WIT UR QUESTIONS AND ANSAS HERE ESP. URSELF,MAYORALL AND ODAS...AM AN ASPIRANT TOO AND WUD LIKE TO GET MORE QUESTIONS FROM YOU GUYS

Aspirant

michaeltotti: tanx@buzygy..are u also an aspirant or a student of oau?

Watz da funtn of calcium fluoride in the xtractn of ca?a.to prevent damag of electrdes b.to raise da meltn point of da electroly c.for economic purpose d.to reduce the rate of da reactn

Wrong!

Simplefemo: photosynthesis

Av u evr bn to water-coop. Or sn a water purifictn plant b4?if No,i guez so!

Michaellegend: hmmmmm... Dat is wrong.
Purification of water 4 town supply (1) water 4rm rainfal, river, lake or borehole is stord in a large tank and exposd to sunlight to kil bacteria during dis period sedimentation of insoluble matter occurs. (2) it is then filtered to remove large particles. (3) the water thereafter is passd through a flocculation tank where coagulant substances such as alum are added. Lime,Ca(OH)2 is added at dis stage to ensure favourable pH for flocculation. (4) it is treated with germicidal chemicals such as chlorine or bleaching powder to kill bacteria. CuSO4 crystal may also be added to inhibit fungal growth. D water is then ready for distribution.
Did u get dat.

C-prevents blackenin of da filamnt

Michaellegend: d. Prevents rustn of da filament

Watz da funtn of da mixture of argon-nitrogen in filling lamp filament or bulb?a.prevents reductn by air b.prevents oxidatn by co2 c.prevents blackening d.prevents rustn of da filament

Germinatn,u cn chk tru a gud text.

edreesabiodun: What's the answer then, remember alkaline pyrogallol is used to remove oxygen from air

No

Sarcasm01: It's 4 respiration they use alkaline pyrogallol for

which of da follown experimnt makz use of alkaline pyrogalol? a.germinatn b.respiratn c.photosynthesis d.transpiratn

edreesabiodun: Which of the following is insoluble in water a) ethanol b) HCl c) ether d) NH3. (2) which of the ffg will form a white precipitate with AgNO3 a) Butane b) ethene c) ethyne d) benzene 3)ethene will change the colour of KMnO4 from purple to what in an alkaline medium a)brown, b)yellow c)green d) reddish brown
