I was kinda skeptical about that sucrose
Where did you get these questions from as in what year.....

Do you mind answering the one on markovniskov rule and asymmetrical alkane.

in the case of the unsymmetrical alkane is called wurtz reaction where alkane is formed from the rxn BTW an haloginoalkane and sodium

in the pressence of peroxide only HBR (hydrogen bromide) does not obey markovniskov rule cos the hydrogen adds to the carbon double bond with the lowest number of hydrogen e.g, Ch3-Ch2-Ch=Ch3 + HBR - - - - - - Ch3-Ch2-Ch2-Ch3BR the hydrogen from the bromine added to the carbon double bond with lower numbers of hydrogen and its called the peroxide effect

3. glucose and fructose
4. soap and glycerol propane 123 triol
Cc: Genius101
The remaining two, I can't remember.....I'll have to re-check my book

not really bro 3.would yield a yellowish brown liquid called caramel for sweetening nd confectionery 4.alkaline hydrolysis of alkanote yields salt of an akanoic acid and alkanol.. Wat u stated is alkaline hydrolysis of fats and oil e.g, Ch3CooC2H5 + KOH - - - - - CH3COOk + C2H5OH (potassium methanoite and ethanol

1.unsymmetrical akane is formed from an extreme reaction of sodium and haloginoalkane by_________reaction 2.in the pressence of peroxide, which hydrogen halide does not follow markovniskov rule 3.whats the product formed when sucrose is heated below its charring temperature 4.the alkaline hydrolysis of alkanote yields______and______

The Bob of a simple pendulum is set into oscillation. When the Bob passes through the lowest point of the motion, the suspended string is cut. If the Bob is then moving with the velocity of 0.8ms-¹ at a vertical height of 5 m above the ground, determine the horizontal distance traveled by the Bob.
(This is Motion Under Gravity not Simple Harmonic Motion)

using R=ut got 0.8m

castrokiller:
guy explain your answer if there is any

there is nothing to xplain bros it's just a series of how sexual reproductions occur in spirogyra in terms of conjunction. The first thing is that the filament of two opposite spirogyra lying side by side forms a wall where the outgrowth called d protubelance is attached that's 5 followed by 4,1,3,2 where 2 is the final stage

castrokiller:
The following events take place during conjugation in spirogyra 1. The protoplasm of each of the conjugating cell separate from the cell wall to form a Gamete; the gamete of one filament passes through the conjugation tube to meet the gamete of the other filament 2. The zygote soon become surrounded by thick brown wall to become zygospore which burst after a short rest and germinate to produce a new filament 3. The nuclei of the gametes fuse to form a zygote 4. The protuberance meet and where they touch the cell-wall disappear so that a conjugation tube joining the two cell is formed 5. protuberance appear on the wall of the cell of two filament of spirogyra lying side by side opposite one another. Now what is the correct sequence in which the above sequence occur?

A. 1,2,3,4,5
B. 1,2,4,5,3
C. 3,4,5,2,1
D. 5,4,1,3,2
E. 5,4,3,1,2

D

Nacl z nt held by metallic bond...its d atoms of Na itself that r held by dat bond and nt NaCl

yeah ur right Nacl is an iconic solid having ion at their lattice point...

Optimist1998:
Which of the following statements is correct about sodium chloride in the solid state?
A. it exists as aggregates of ions
B. it conducts electricity
C. its melting point is below 100oC
D. it exists as discrete molecules
E. its ions are linked by metallic bonds

Which of the following reactions is not feasible?
A. Cl2 + 2Kl → 2KCI + I2
B. Cl2 + 2NaF → 2NaCI + F2
C. Zn + CuCI2 ZnCl2 + Cu
D. Zn + 2AgNO3 → Zn(NO3)2 + 2Ag

since the Nacl is in solid state, E should be the answer cos solids have three dimensional shapes controlled by the type of force holding their crystal lattice structure together hence Nacl is held by metallic bond such dat each Na is surrounded by Cl ions nd each Cl is surrounded by Na ions nd since inter ionic bond is strong Nacl has high boiling point. It should have been (D) if the Nacl was in liquid state

Wish all university provosts can be this Humane unlike some schs delsu and unizik, they will tell you meet the registrar, registra will ask you to go meet the vc

Kendzyma:
But what if she only submitted 7 courses?

she couldn't have cause they were asked to upload it

calebify1:
so sorry bro.
had couple of guys who got into delsu medicine with no help and surpassed d cut off.
your slot may av been swapped.

lol what can one do? Though it will be almost impossible to repeat such fit again in jamb cos I no go lie u bro to study now tire me

calebify1:
That's really strange. what was ur aggregate??

cutoff was 65 and I had 66

calebify1:
so u were offered nothing??

that's right even though the school released up to 5 admission lists.. Bros I tire o.

baum1:
Guy, if you are truthful, post your results like the young girl and we will do follow up.

I am interested in why our excellent students, near geniuses and geniuses are not getting admitted by our good schools in naija, after the students have worked so hard to make elite grades.

OK I will try to do that Bro in fact I once created a topic to that regard but unfortunately, it never got to front page to draw attention maybe because am not a girl. Lol

calebify1:
Did u visit the admission office??

yeah I did and was told someone from my local government scored higher than me and and got it. And I was like what's my own with someone from my local government since we both beat the cutoff besides Cutoff marks are set based on performance of all candidates. All tertiary institutions in Nigeria are corrupt and need to be probed

The truth of the matter is that she isn't the only one in such mess I for instance had310 in jamb and beat the cutoff for med&surg in delsu which is my state but was not offered admission. It's high time all the universities in Nigeria are probed.. Am very sure there are so many of us out there with same problem. I know some people will say go to the school to complain but I know from my time in unizik that going to the school to complain will be futile that is if anyone will even listen to you.

simba1:
Yes. Okofia Kampus

good lucks bro

jnichole:
please i saw one of your posts where you wanted to switch but was nt allowed to please how possible is my switching from physiology to nursing in unizik?

to be plain with you Bro, it is not easy

simba1:
Not entirely true brother. A matriculated std can even re-apply Jamb in same school. Couple of my peeps have done it and many more are doing it. NO MIND JAMB WITH THEIR LOUSY SO CALLED RULES. Which are u now? When did u left, 200L?

[quote author=simba1 post=51973308][/quote]yeah stopped after 200 levels but am still in the town sha (ifite).. Have you resumed

simba1:
Genius how far? Which college u dey?

used to be a zikite but stopped when I couldn't switch.. It's e even more difficult now because a matriculated student of any uni won't be allowed to take jamb meaning you can't be in school and still resit jamb so if u don't like the course you are given, it's better not to accept it if your not sure of your chances of switching because if you do you would have to finish that course before applying for another jamb unlike before where one can be studying a less preferred course and still be writing jamb

jnichole:
please how much are we talking about here cos i just lost my dad i need to plan and strategise very well cos of financial reasons

100k but 50k for staff children then you pray your h.o.d accepts to signs you out

state universities are just too corrupt.. had a jamb score of 310 even beat mbbs cutoff in delsu but not admitted in both merit and 2nd batch plus am a deltan o.. guys dont give up o just keep praying and believing

youngest85:
cn u pay d price?

U knw as e deh go nw

boss i hail thee o
