Temicare: Orh! u no go vex ni...na so pple dey do...n dey will b screamin!...pls hlp me dis! pls hlp me dat...wen dey get d hlp...proudness(i dont even know wat) dont allow dem 2 say d pure simple word "tank u"...even God wont here ur request without thanksgivin...U guys shld change...we dey 2geder na

Lol. Its a terrible thing. I'm just not in a very forgiving mood this morning. Temi love, happy preparations oh. It'll soon be our turn. Lemme go and read...I have another entrance exam to prep for. Unilag msc programme. U can imagine the stress of reading for both. Abeg pray for me. Lemme go.....xoxo

samerikx: STORM2 and DANOX....or anybody! PLS SEND A COPY OF D.E PAST QUSTION MEDICINE AND SURGERY to me at SAMERIKX@YAHOO.COM. I PRAY WE WILL ALL PASS IN JESUS NAME. PLS HELP ME FOR GOD SAKE!

Will it kill u to say thank u? Abi u wan claim say u neva see am? Mtcheeew.

danox: Pls,I need the past questions for Medicine And Surgery.My Email add is dagbroko@yahoo.com.Pls,help a brother.

I hope u got my email? Goodluck.

Temicare: D info dey blink....Uniben never announce d stuff officially...

See as I just dey fear....my heart wan burst eh! Pls oh

Eeya 7 days to go...
Goodluck oh..Godspeed.

English again...lol...I did some research. Its more power to your elbow ( or in australia more power to you)
More grease to you elbow is also correct...but in an exam if both of these variations of the idiom appear, u should choose the former (i.e more power to your elbow)

Mcslize: u mean the question we are arguing has Automatical time and current? Not at all

look at that my example, u see that the current is given to u which is 2ampere and the time is 30minutes. Meaning u gotta calculate using Q=It = 2 * 30 * 60= 3600C U will now divide it by 96500

sylvalord question will by no means has automatic current and time.

Kindly give the question to final year Chemistry student to solve or any teacher.

Nah...I'm not getting into this. Good night. Lemme go and do sth else. Atleast 2ppl have understood what I've said. U will eventually b4 the exam. And u will do well.
Oya oh...hugs and kisses bye bye for today.

Mcslize: U are wrong. Pls think of the question. The question didn't give us current and time so u can't use 95600c. U can only use that if the question give u the current and the time it took for the current to deposit the element & thats wen u will apply that method u explain above by using the formular Q = It to calculate the number of Columb.

But the question only ask u to solve directly for the amount of cu deposited.

To support what I said below are two examples:

Example 1:
In electrolysis, a metal cation M3+ is liberated at the cathode. Calculate the mass of M deposited when a current of 2 ampere is passed for 30 minutes ( M= 56, R faraday= 96500C)

looking at this question above, ur above method can only be used to solve problem like this cited example because the current is given and time is given.

Don't mistake this kind of question with the one set by slvalord. They are different entirely.

U were not given the current so why should u be using that method?

That ur explanation can only be used to solve the example I cited above not the one that sylvalord set.
If u still doubt then give the question to a chemistry teacher to solve it he will still arrive at that my answer.

As usual we'll agree to disagree......
I don't know what else to tell u..there is no "rule" to follow. This is simple proportion.
Q=IT.....i.e coloumbs =time x ampere.....so if u have the quantity of electricity u automatically have ur time and ampere...I'm shocked we're still talking about this......

sylvalord: hmm.. I jst checked it again and u might be correct..

edreesabiodun: She's correct actually. It's a no-brainer. Since 18g is deposited by 2F and 1 mole of Cu(64g) ordinarily will be deposited by 2F. Think deeply.

I'm glad oh. Mcslize neva believes me. He thinks I'm a stubborn gurl...

Mcslize: sis the question doesn't ask us to use the copper valence to calculate for the amount of copper

It asked us to know solve for the amount o copper that will be deposited by that 2faraday that deposited aluminium.

If the question had not involve aluminium thats when u can used the valence of copper to calculate for amount of copper. But as u can see the question involve another element which is Aluminium. I hope u will get it right this time around

Lol...did u even read my above post? Its very self explanatory. Just read it well.
But if u keep insisting I'll leave u oh...

@Mcslize and Sylvalord...pls just cool down okay....
How many coloumbs will give 18g of AL3+?
The answer is 2F abi?
This answer simply means that 2Faraday (2x96500Coloumbs) will give 18g of aluminum.
The question now asks how many grams of copper will the above amount of electricity deposit...
Cu2+ requires exactly 2F to give 64g of copper.

This means that 2F (from above) yeilds 64g of copper...
This is a trick question...pls don't fall for it.
Just cool down and u'll see my logic is sound.

sylvalord: gud attempt
score-8/10
grade-v.good
comment- u r good to go girl

Kai! I didn't fail number 2 oh. I no gree for that wan...the question said SAME amt of electricy..u're to solve for 2F not 1F....we go fight oh

Mcslize: sweetheart, the question 2 is asking us to calculate amount of Copper that will be deposited by the same electricity that deposite 18g of Aluminium

Faraday is also known as electricity. Now , from my solving, 2faraday deposit 18g of Aluminium. What amount of copper will be deposited with that same electricity? Thats the question.
All u need to do is calculate the amount of copper that will be deposited with that 2faraday which can also be refer to as the electricity.
So, if 2f deposite 18g Aluminium
2f will deposite 32g Copper

I hope it is clearer now

Remember that copper has a valence of 2
That means that 2F will give 64g of copper
U don't need to solve for 1faraday because the question asked u how many grams of copper will be deposited by the SAME amt of electricity that deposits 18g of aluminium which is 2F
Bros....abeg na...

Donvitalis: Thanks, i've thrashed out the issue.

I'm happy for u.....

@Mcslize, that number 2 remember the question asked for "the amount of metal deposited by the same amount of electricity that deposits 18g of aluminium" not the amount deposited by 1faraday.
I don catch u!
No argue oh! I don catch u!!!
But u know chemistry sha! That one abt lime water pained me!!!! U good!

QuestC: Ok. That's good. I'm actually going for Direct Entry Law!

Bro..I'm sorry u asked me a question earlier and I haven't replied. I'm sorry....didn't see it.

1.A 2.A 3.A. 4.C 5.D 6.C 7.A 8. B 9.D 10.B

sylvalord: u dey find cheap questn.. U no wel

Ofcourse na!! Abeg lemme oh! I tell u say I be botanist? But sha...I heard uniben likes setting mumu questions like that. Simple but TOUGH if u don't read the chapters in and out.

Mcslize: I hope say u don check am up for the two questions u got wrong

4. glucose is the direct product of photosynthesis

7. Protein is the only food sunstance that is digested in the stomach. And more to that it is only in the stomach that P.H is found to be acidic cuz it contain Hydrochloric acid. Other part of the digestive system is Alkaline in nature.

Glucose Omo eh!!! Plant biology has been the bane of my existence since SS1. I only read up digestion...later I'll look at photosynthesis....

Mehlena: make mockery of who?...i dnt undastand u o sis..was jes sayng wat was on ma mind..shikenah

U sef....I wasn't refering to u na...lol
Was actually refering to those mocking ppl asking and answering questions...its unecessary.
Equally unecessary is getting angry with them...let's just all be cool. Oya for real I don go.

Omo na true oh! Nothing like that in modern biology textbook...thanks oh I don learn one. I'm off to brush up on digestive enzymes...I no fit shout

Mehlena: guy na wa 4 u o..u shouldnt tell him those tinz na...whether he wants 2 attempt d Qs or nat is his choice...dat day na O.Y.O state evrybody go they.

Lol @ O.Y.O state.
Answering q's just builds morale that's all. Not that anybody is smarter than anyone. Not gra gra. Its just a way to stay fresh. No need for it to bring mockery or anger..evryone just be cool.
@Mclize, I've seen the one I failed oh..no 7 bah? What abt gastric lipase na? Oohhhmmm joo. I go open text book oh

Donvitalis: I scored 214 and i chose University of Benin as my first and second choice of institution.

My brother....I wish I had some useful help to give but I don't. If u can....try to go to the school as in to uniben directly and seek help. I don't know if anyone on this forum can physically help u with that. And time is really short. Pls just try.

Thank u jare...simpler questions..sylvalord wan kee person with insects and plants and hard fermentation tinz...joo oh
C C D C B A C D C B

lee11: LOL Initial gra gra. I know una type.

Lol...its just fun...no gra gra involved....

Okay oh..I always thought anaerobic respiration in muscle cells produced lactic acid which is responsible for muscle fatigue...but I'll rest cos frankly I don't even understand the mechanism behind that one. Just look it up. Meanwhile if I see that question in the hall, I'll pick ur answer lactic acid it is. But seriously, look up anaerobic fermentation and muscle fatigue. U guys are right...muscle cells weren't mentioned in the question so lactic acid should be the answer. I just love u guys sha...

Okay...questions for a mr sylvalord...
So caterpillars make silk? Is it to catch food like spiders? I can't find it to read up and I'm scared oh. Pls drop more insect info so that uniben doesn't kill us.
Second question...emmm...anaerobic respiration in muscle cells...doesn't that produce lactic acid? To be honest I'm confused oh cos when I saw that question I felt all the options were possible. In the future how do I pick the "best" answer?
Thanks...#anxiously waiting for more questions#

Mcslize: Some people do expo o.

Hahahahahaha! Bro abeg leave me oh!
