SamanN:


I really hope you start afresh a medicine student, the number I think would double up; because of the increase in tuition fee for medical students in UI.

Preparation for POST-UTME??. I just joined a group on WhatsApp, i think that should help. The stress i'm facing as a fresher is making me disorganized. Imagine a Lecturer assuming you have seen a question and he starts solving. I'm trying my best to balance both end. I hope you have something for me that can enhance my learning also.

yeah I guess every body go rush go oau Now due to ui fees palava but I smell oau increasing there fees in no distant time

CHEMISTRY.

1) Which of the following is the relative molecular mass of a compound which has empirical formula CH2O? ..........
(A) 42
(B) 45
(C) 126
(D) 145
(E) 180

2) Which of the following terms indicates the number of bonds that can be formed by an atom?
(A) Oxidation number
(B) Valence
(C) Atomic number
(D) Electronegativity


Explanations will be highly appreciated!

1..

Now we all know that (empirical formulae) n = relative atomic mass right
Empirical formulae for d compound is ch2o=12+(2*1)+16=30

n=is always a whole number
With dis said you should know Dat d molecular formulae /relative atomic mass should be s multiple of d empirical formulae (30 in dis case)
In d above option only - is a multiple ...u should be able to get it now with d explanation

2.
Valency is defined as d combination power of an element invariably d determinant of a chemical combination

Oxidation number is d charge an atom as both in free or combined state

Atomic number is d number of proton in an element

And electronagativity is d tendency to attract electron.. Which is limited to only non metals

So with d following definition u should be able to pin point d answer ur self abi.

I rest my case

Which of these has zero resistance..(A) semi conductor (B) super conductor (C) perfect conductor (D) conductor

He is back ooo
My boss is back
Welcome sir

I think na perfect conductor c...
It is a conductor dat as zero resistivity or resistance and non ending electrical flow...
I stand to be corrected

Ans... B

Damayogenius18:
In case of Intermolecular force,hydrogen shld normally av the lowest BT when I was reading, i saw this and I think it is appropriate to share it with you guys...the weakest intermolecular force is vander Waal's force...vander waal force increases as the number of electron of a species increases...hydrogen has the least electron and should have the least Intermolecular force BT somehow its helium.... I dnt also know why... A way around this is to remember that.. Helium is the most ideal gas(followed by hydrogen) the reason is because it has the least Intermolecular force....thanks guys... Am signing out finally..

Ummm I c

Nice dude

DrBESTJC:



Boss, I de hail oooo....

Sir,this your statement shocked me to the bone marrows and sent cold shivers down my spine......I mean,it really got me thinking!.It takes unimaginable courage to set a goal as this...


The last time I wrote UI post UTME,I scored 53(though not prepared at all due to some circumstances in my life then that were beyond my control).I am not the 'marathon jacking type'......my own na 'slow and steady'....





Abeg no leave us go into exile ooooo.Boys like us are really learning from bosses like you,Pes13,Orezy5,condomsir,boyejo123,Afoobabs,....and many others.

I can tell you that my high score in Jamb can as well be associated to the priceless tutorials I got from bosses in this forum...

There are so many things we learn here in seconds which can take you weeks to come across in textbooks.

So please,LET US JOINTLY HELP OURSELVES GET OUR HEART DESIRES THIS YEAR(Especially UI students(Even though we are still aspirants,but we don enter be that ooo ))

Many HEADS are always better than one!!!

True talk Jor
Abeg my brother watin u score did time jor

Damayogenius18:
What is/ are the chemical bond in carbon monoxide.. (A) covalent ( B) dative ( C) covalent and dative ( D) vanderwaal and covalent

Answer.. Covalet bond
Y??
Ok c
D carbon as 4 electrons abi..valency oo
Oxygen as 6 abi .....

Now for dem to complete an octet rule each must have 8 valences abi

If carbon donates 2 electrons
And oxygen 4 Electons it mins 6 Electons Is binding dem together abi forming a triple covalet bond between dem
Now draw what I just said in a paper and count d number of electrons in each participating atom. (oxygen and carbon)
What did u find out each as a complete octet abi

Day solves it

But our oga go say wrong
But Dat d answer oo

Damayogenius18:
Which of this has this gas has the lowest intermolecular force..(A) hydrogen ( B) helium (C) oxygen (D) Nitrogen

Note rate of diffusion is inversely proportional to d relative atomic mass naw did says Dat d lower d diffusion rate d higher d molar mass of such element
For a gas to have a low diffusion rate d gas must have strong intermolecular force to bind dem together and resit set independent motion of d molecules of d gases in question Whit did said
Oxygen has d highest molecular mass hear so it has d lowest diffusion rate giving it d highest molecular force
In contract hydrogen has low molecular mass hence it posses d lowest intermolecular force... Answer is A

Also note dat d lower d density d lower d intermolecular force
Dis explains y hydrogen is used to fill balloon
Helium. Is also used but Dat if hydrogen moves faster due to loosened inter force..... I rest my case

Damayogenius18:
..no answer? Where are the doctors in the house..

Abeg no mind egbo oo d answer na fluorine oo
Electron affinity increases across d period and decrease down group for group 7 it starts with fluorine followed by chlorine then bromine so u c d electon affinity decrease hence d highest electron affinity goes to fluorine

Affinity ...ability to attract or wanting to gain
Electon.... Nagative charge particle

Put it together and form d answer
Now remember dat fluorine can displace any other elements in its group from der salt... Day to show u it Hunger for electron but chlorine can only displace does lower Dan it... Bromine iodine
Also it is d most electro nagative element


Don't be deceived fluorine is d answer

ivumar:


sorry to disturb bro,but how is Dolapo74's answer correct?... mind you, the question is a logical one. They were asking you of " which element/compound"... So I don't see a reason why the answer should be an atom.Also,the question asked about bacteria in general,,not just anaerobic bacteria. So if at all oxygen attacks anaerobic bacteria(Which I don't even think is possible), i don't think it will attack aerobic bacteria.So it should be a compound or an element as the question rightly asked. I think the answer is A. Or what do you think?

Abi ask our boda watin happen to aerobic bacteria oo I chose A even gave him reason

Damayogenius18:
seriously,plant stem does not have cuticle..you need to do some research...although cuticle are mainly found in leave,some stem have cuticle..Even,some aeriel root has cuticle...BT their cuticle is thick not thin..that's why the Answer is (A)....I made a mistake the other time saying root does not have cuticle..

I tire for u ooo

First we arrived at d same answer abi
D text book I use didn't affirm. Dat wer exist cuticle on roots oo

Cuticle are found on leaves upper part
Stomata... Lower parts of leave
Lenticrls on stems and root

[quote author=Damayogenius18 post=66234209] another mistake u made is that u said bird of prey use claw to cut flesh...no,they don't...they use their beak to cut and tear flesh...I expect u to have solve this in jamb pq...2013




Ummmm basically dey employ both d claws and d beak
.. And more over isn't it d same answer we got chaii

Beaks.. Used to cut flesh of caught prey
Claws use to grip.. (in d process of gripping is d prey not been cut by d claws I.e d claw performing flesh tearing action) also it is used to kill prey ( in killing won't d bird scratch up it's prey hence claw perform Inc d action of flesh tearing) ummm egbo u bad oo

How many orbital are found in third energy level...(a) 16 (b) 9 (c) 11 ( d) 15

Bro u sure of d question
If it's d number of electron it is 18 ..m is third energy level using 2n^2=2*3^2=18
If it d number of sub shell it is 6
Non of ur option conveys Dat

Which of the following is false about the piliferous layer of a root?It
A has a thin cuticle
B is the outermost layer of the cortex
C may bear root hairs
D breaks down with age
E is replaced by cork in old roots

Piliferous layer gives rise to root hairs in young plant with time it is filled with deposits of cabin cells (dicots)which form a cork with dis explanation c and d as been erased abi
It is an extension of d cortex and epidermis... B cancelled
Answer A... Y because cuticle are only found in leaves old leaves to be precise dat y we have curricular transpiration if it is found in d root den it can't take part in transpiration process
Secondly it is only lenticel Dat can be found in both stem and roots not cuticle (it's like a water proff covering in thick leaves) or stomata......... I rest my case

Biology please
The foot of the bird has a strong claws on its digits this implies that the bird
A is a scavenger
B. is a bird of prey
C. uses the foot to supplement wing action
D uses the foot to scratch the ground

B..
Birds of prey includes eagle owl etc
Dey can be said to have d most powerful claws and digit because they have d ability to carry prey on air in other to do dis dint u think dey need very strong claws.. Example haven't u cen a snake being carried by an eagle.. What can a hen carry with it claws although it too posses string claw but Dat if bird of prey is superior
Dey also need dis to cut through flesh and even bones in some cases.... I rest my case

A car towing a trailer is accelerating on a level road.The car exert a force on the trailer whose. magnitude is
A the same as that of the force the trailer exerts on the car
B the same as that of the force the trailer exerts on the road
C the same as that of the force the road exerts on the trailer
D greater than that of the force the trailer exerts on the car
E none of the above

A.. Using newton third law of motion there exist an equal and opposite force... Both forces are equal but acting in different directions

thanks..I know u scored 80+ in lastyr pjamb...wanna ask,if u are to turn the time back,what could you have done better to get 90+...also how did you treat the passage question...did you leave it and come back to it later? Also I read u said u finish the 100 ques..how were you able to manage ur time?.......sori bro,I thought it was Pes13...

Chaii bro
U are writing not talking na

Wen u knew I wasnt boss pes13 y did u still go on,in posting it ..? U funny oo

Damayogenius18:
My desire is to score 100% in pjamb..is it possible?.. I don't know BT I will try...Am so focus on doing that BT it takes God...I don't care abt my jamb score or getting MBBS...i just wan2 score 100% in UI post utme...hope u wnt see it as bragging(m not that type)...

Strong words sir relly strong words
Aim high
Prepare higher
Achieve it!!

But he no easy oo

Bobola07:


Let me clarify the two types of COC.

You can do jamb COC when its out. that one is done before postume. there is also ui COC, done after postume.

Now, if you're sceptical about your chances, I'll advise you take jamb COC. You can change to any other choice course of yours.

The reason I'm saying this is because you'll still have the liberty of choosing anything you like for yourself.


IF you wait till after postume before doing UIs COC, you'll be limited to only the available courses UI gives out. last year. there was no other course in college of medicine for COC. not even biochemistry or physiology. MBBS aspirants had to do COC to botany, chemistry and co, still, some didn't make it.

summary- if you wanna change your course, its best to change from jamb, and do your best in postume to gain admission on merit

Long time sir

Congrats once again it wasn't easy oo

MrHistorian:

I shouldn't have replied to this,really.

But for the sake of the silent observers who might get easily convinced by these loads of baloneys you keep recycling on this forum,I will type a few words.

I don't know of any time or period when PMB approved of any murderers in this country to kill people,please if you know any,you can forward a letter(attached with evidences) to the International Ciminal Court.If by any chance what you mean is the recent killings by the marauding Fulani herdsmen,needless I remind you that the conflict between farmers and herdsmen started long ago as far back as before the return to democracy in 1999.

Truly,you can't totally absolve PMB neither can you solely rebuke him for the killings,he is just a 75 year old man who resides somewhere in Aso rock.I really don't know how you expect such a man to be directly involve in any altercation that erupts in Benue.The sitting governor of the state holds firmly the seat of the Chief Security Officer of the state. . .Why does he find it hard to implement assertive policies and heighten security level to ensure peace in his state? But you are one of the very naive Nigerians who gullibly believes whatever the media throws at them.

Also,PMB does not intend to make the electioneering process a do-or-die affair,stop heating up the polity,you mischief maker! The constitution has stipulated how election winners are determined.The nationwide political support for PMB is enough to fetch him a second term without any stress(cash that in any bank).

I know since all corruption loopholes have been blocked,staying alive has been a misery for people like you who feeds from the crumbs of looted funds.I feel your pain bruh.

Nltaliban:
congratulations, youve taken a bold step by choosing the first and best institution as your first choice.


Ui cut of mark for all courses over the year has been 200, and there is little or no probability that it will change this year. however,your course is a very competitive one, try as much as possible to score above 300 that way you'll have a better chance of admission.,

once again i congratulate you for having the boldness to choose the institution, i wish you all the best in you quest for admission..


feel free to post any question bothering you here, the bosses in here will be willing to help.

Quite bold
