no. wonder UI is still the first and the best cos her students really collection of the bests.......

@estijas, u murdered the question with great ease....

I ve actually accessed the answers and they re perfectly on alignment

FIGHTING

lol,av got d number 1 too since u did not gimme sinZ,I got sinz myself cos
(sinz)2+(cosz)2=1
therefore sinz=√[1-(cosz)2]

so d ansa to question 1 is:[L(L-1)]/[{√(1-L2)}(1-L2)] or (L2-L)/[{√(1-L2)}(1-L2)] or -L/[(1+L)(√1-L2)]

Hyp=1, adj=L. So to get the other side we make use of Using Pythagoras theorem. Let the other side be x, therefore x=√{1-L^2}
CotZ=CosZ/Since, CosecZ=1/SinZ and SecZ=1/CosZ

(CosZ/SinZ -1/SinZ)/(1/CosZ +SinZ/CosZ )

[b] ==> Reaction between Alkanal and hydroxyalamine yield Oximes.

.
===> Balmer series can be seen in the second energy level.

.===>The nature of Balmer series include it has 4 possible light which include red,indigo,violet and ultralight colour which all have a wavelength of about 400pm and to the nearest 700pm. It usually jump from the series of Higher energy closest to the nucleus to the lowest.

.

===> Iodine and bromine discover by Courtois and Balard

.

===> H202 can easily be oxidized on exposure to air/sunlight so it is stored in Amber Bottle lined with Dark component

.

==> enantiomer are stereoisomer that are non superimposable without the mirror light image lyk a racemic mixture(i.e mixture of dextrotary and laevorotary). So they are non super imposable because they can't exactly look alike even if they slide over each oda i.e No mirror like images
.

==> Terminal Alkyne undergo substitution reaction a typical example can be seen in dia reaction with AgN03 to form white ppt. It distinguish btw terminal alkyne and alkene
.
.

===> A set of optical isomers is Called enantiomers [/b]

1. Protons and neutrons are made up of smaller elementary particles called "quarks". Electron is just one of the so many elementary particles

2. Charges depend on which type of quark. E.g Up-type Q has charge + 2 / 3, down-type Q has - 1/3. Their charges are fractional.

3. Energy level 2

4. It is used in describing d spectral lines emissions of hydrogen atom using the six balmer's series.

5. Dark bottles prevent the H₂0 ₂ from reacting with light which can break it down.

6. Courtois and Balard respectively.

7. I dunno this.

8. Oxime

9. Molecules are superimposable if after placing them on top of one another they still give the same molecule. Enantiomers don't work this way so they are not superimposable.

10. Akynes undergo substitution reaction because of their high electronegativity.

You guys should stop posting things as no one is gonna ask you what 'Quark and Leptons' or where 'Phospholipids and Proteins' are found as a bilayer...let's concentrate on the things JAMB would probably set. I don't have to remind anyone that we are in Nigeria and everyone here, as far as I am concerned is gonna seat for UTME not SAT or TOEFL. #constructivecritisicm.

To the Arts and Commercial guys a few questions
