in 2017, i fell on friday exam, buh it wasn't easy. 90% of the physics & chemistry were pure calculations..

those on Saturday were very lucky..

Same thing happened to mee ooo...last year Friday exam was tough...I got 45

3. The hardest substance known to man is DIAMOND .

4. The lowest Oxidation State of IRON is ZERO

5. Quantum Numbers only describes ELECTRONS and not ATOMS.

6. Hydrogenation of Alkynes gives Alkanes

7. The Law of Definite Proportion is also referred to as the law of Constant Composition .

8. Sodium liberates H from Water = False.

*Sodium liberates H from Steam = True

9. The electrolyte used in DOWN CELL is Molten NaCl fused with Cacl

10. Na is not stored under water because it Tarnishes.

11. Burning Kerosene gives CO H O

12. Dissolution of Calcium in water gives CaO.

13. All Nitrates are Soluble in water. Also, all nitrates
unstable to heat.

14. NO is the first Anaesthetic man ever used.
15. The flame used by welders is called Oxy-acetylene flame

16. Consecutive members of the Alkane homologous series differ by CH

17. The difference between drying and dehydration is that drying is removal of water while dehydration is the removal of elements of water (Hydrogen and oxygen).

18. Benzene is an Aromatic hydrocarbon.

19. Atomic mass is the mass of proton and neutron in the nucleus of an atom.

20. Atomic number is the number of Electron an atom has.

21. Electrons revolve around the atom while Proton and Neutron are inside the Nucleus of the Atom.

22. Radioactivity is the spontaneous disintegration of the nuclei of an atom to emit energy and radiations such as
ALPHA PARTICLES, BETA PARTICLES AND GAMMA RAYS.

23. Alpha particles have the least penetrating power. Beta particles can be stopped by Aluminium foil while Gamma rays can only be stopped by LEAD BLOCK .

24. The ability of CARBON to form long chains, branched chains and ring is called catenation.

25. Elements that can combine with carbon to give compounds are:
Hydrogen
Oxygen
Chlorine
Nitrogen
Bromine
Phosphorus

26. Aliphatic Hydrocarbons could be Cyclic, Acyclic or Alicyclic.

27. Pure substances have definite boiling point and melting point.

28. Example of radioactive material are Uranium, Thorium and Polonium.

29. The most notable scientist who contributed to the
development of Periodic table between 1817 to 1895 was Dmitri T. Mendeleev

30. The fourth and fifth period contains 18 elements each.

31. Elements in the same group are called CONGENERS.

32. Free Hydrogen (H ) is the lightest gas known.

33. Viscosity is the resistance to flow in liquids.

34. Water starts boiling when the saturated vapour pressure is equal to the atmospheric pressure.

35. Factors affecting boiling points of organic compounds are branching, volatility, polarity and impurity.

36. The most reactive nonmetal known is fluorine.

37. Impurity increases boiling point but reduces melting point.

38. Ernest Rutherford is the father of nuclear science.

39. Radioactivity can also be called transmutation.

40. NUCLEAR ENERGY is produced by Nuclear fission and Nuclear fusion.

41. Energy from the Sun is as a result of Nuclear fusion but reaches the earth via Radiation

42. The two types of radioactivity are natural radioactivity and artificial radioactivity.

43. Every nucleus is positive.

44. For solid which sublime, sublimation can be used to isolate the solid from its impurities if the impurities themselves do not sublime.

45. CRAO.. Reduction takes place in cathode and oxidation occurs in the anode.

46. Compound that rotates plane polarised light is said to be optically active.

47. Cathode ray tube was the forerunner of of today’s television tube.

48. R.A Millikan found the charge of an electron

49. Antoine Becquerel discovered Radioactivity while Marie Curie suggested the name “Radioactivity”.

50. Each Hydrogen spectrum produces six series and each series produces lines while each line has specific wavelength

Thanks bro....more of it. This will be useful.

A physics student adds two displacement vector of 8.0&6.0 km, What's the resultant vector?

resultant vector=8km+6km=14km (since no direction was given)

Nltaliban:


When is a nucleus considered unstable?

When the strong nuclear force does not generate enough binding energy i.e when the nucleus does not has a strong binding energy. It is also when there is no balance between the protons and neutrons in a nucleus.

Nltaliban:


A baby is said to be in uniform speed when?

A baby is said to be in uniform speed if he covers equal distance in equal time interval, no matter how small the time interval may be.

Nltaliban:
While micro is 10-6 Femto is?

10^-15

please somebody should help me out what weight of HCL is present in 155ml of a 0.540 solution?? thanks

molar concentration C=0.540mol/dm3, molar mass of HCl M=1+35.5=36.5g/mol, mass/weight m=?, volume V=155ml=0.155dm3 (1dm3=1000cm3=1000ml)...Using the relation: m/M=CV..m/36.5=0.540*0.155 >>> m/36.5=0.0837 >>> m=36.5*0.0837 >>> m=3.05505g.

Eben331:
resultant vector=8km+6km=14km (since no direction was given)

so why did you add when no direction was given?. It could have been addition or subtraction.

It should be 8±6=2-14.

That question was in last year's question I think

I forgot to subtract also, thanks for pointing that out. So this question was set last year? Truly, UI questions are technical. Pls post more of it. Is the answer to the question 2 or 14 OR 2 to 14. I am just curious to knw the right ans.

Nltaliban, do I need to upload my waec result again?? When I checked my print out on the portal, it was blank. .

Quick reply please..

The concave shape of a bird's wing during flight, ensures that the greater air pressure under the wings will : A.counteract the effect of gravity. B.lift the bird so that it can remain airborne. C.enable the pectoral muscles to contract easily. D.change the direction of the flying bird. ??
