Pls is there anybody here attending Ui's coaching classes

Anybody here attending Ui's coaching classes

Abeg bosses here,I need clear explanations to the correct answers to these questions....It's kinda confusing....

CHEMISTRY.

A) Sodium hydroxide solution
B) Chlorine water
C) Pure water
D) Sodium hypochlorite solution
E) Hydrochloric acid solution.

B) Chlorine water
C) Pure water
D) Sodium hypochlorite solution
E) Hydrochloric acid solution.

A is the answer. During the electrolysis of aqueous solution of sodium chloride. At the cathode, we have H+ and Na+. But H+ will b preferentially discharged and liberated at the cathode. At the anode, we have OH- and Cl-. But Cl will be preferentially discharged since OH- and Cl- are close to each other. Cl- is liberated at the anode. This leaves out Na+ and OH- in the electrolyte making the electrolyte alkaline.

2) If 48000 coloumbs of electricity are required to discharge 0.5 mole of sodium from a molten sodium chloride mass, then the number of coloumbs required to discharge 2 moles of Lead from molten Lead(II) chloride is :

C) 192000
D) 384000
E) 576000[/quote]
48000C produces 0.5 mole of Na
X Coulombs will produce 1 mole of Na
48000/0.5 which is equal to 96000C
1 mole of Na equals 1f which then equals 96000C
Therefore 2 moles of Pb2+ equals 4f
Which will then produce 96000*4f which is equal to 384000C (D is d answer, i think)

A and D



Na+


48000c=1/2m


1m=48000×2=96000c



Pb2+


2f=1mol


4f=2mol



4(96000)=2mol



384000c=2mol



384000C is correct...

the cost of electricity that liberated 1g of Magnesium is #5, find the cost of electricity that would liberate 10g of Aluminium....

Gud morning guys.

someone asked me some questions via a private message , but I choose to reply here so that it will benefit everyone else with the same questions.



Does UI set biology questions in putme from O level or A level?.

UI biology is 100% olevel, you won't find one single A'level, in fact, you will meet jamb past questions. Most students score 20, 22, 25 out of 25 in UI putme biology


What should I read to score high in Biology?

Essential and past questions(UI and UTME) is enough. If you have modern biology , it's ok


What should I read for Chemistry and Physics?

Ababio, new school physics or Nelkon physics. Add all past questions to it. If you have lamlad, please read it, we have seen Putme questions lifted word for word in lamlad physics and chemistry.

Do you have any tips that will help me to perform excellently well in UI post utme.

Read the way you read for jamb, but just practice without calculator, to help your speed and accuracy.

And for people who want to know my UTME and putme score. I had 322 and 80% in UTME and putme respectively. I can categorically tell you, UI putme is very easy.

Hello UI bosses here....

Please this is very very very urgent..!!!

I have two friends who got 309 and 302 respectively in this year's Jamb exam but were not offered admission(to study medicine) in UNN due to the competitive nature of the school(i.e. Their names did not appear on the merit list that was just released)...

Their question now is...

1) Can We do a change of institution to UI since they have not conducted their Post UTME exam...??

OR

2) Is there any other thing we can do to get admission in medicine this year with our Jamb score..?....no matter the school..??
