boofydon:wow cao's biography... this is definitely interesting |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by cao(f): 7:46am On Dec 20, 2014 |
boofydon: Still not my name, nor my profession. Where the heck do you get these names from? |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 8:04am On Dec 20, 2014 |
cao:it is, its not, it is, its not... the both of you should make up your mind. Clara is a nice name tho, in fact I'll be calling you Clara till I get to know your real name |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by boofydon: 2:48pm On Dec 20, 2014 |
cao:from your fb page |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by cao(f): 4:10pm On Dec 20, 2014 |
boofydon:And if you do know my fb page, you'd know I answer my second name. @Preboy, I don't have any English/Germanic/Hebrew names, all igbo names. Anywho, enough about me, this thread is about JAMB, bring on the quicklime. |

Preboy: boofydon: cao:Interesting. [size=25]Enough arguments on names[/size] |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by cao(f): 1:57pm On Dec 23, 2014 |
adebayour26: We had stopped, but you just brought it up again. |

Take my seat.....how many lecture have i missed now? |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 8:27pm On Dec 23, 2014 |
adebayour26:bro, when is the next lecture coming up, we're already behind schedule |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by adebayour26: 9:35pm On Dec 23, 2014 |
Preboy:i know, am just seriously busy these days, and typing is a bit not easy. That's why I do encourage questions. |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 9:53pm On Dec 23, 2014 |
adebayour26:I understand, maybe we should go on a Christmas break and resume 2nd Jan |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by mathefaro(m): 7:43am On Dec 24, 2014 |
adebayour26:if you won't mind? I think I can help out in some areas |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by adebayour26: 2:26pm On Dec 24, 2014 |
mathefaro:I don't mind, so far It's of academic assistance to everyone on this thread. I'll also contact Kudderich to inform him. Thanks. |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 4:09pm On Dec 24, 2014 |
how can I be of help here I really can't type; explanations and definitions. so I thought this question might be important. What mass of magnesium will be deposited in the cathode of an electrolytic cell when 10Faraday of electricity is passed through it. (Mg2+) |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 4:20pm On Dec 24, 2014 |
adebayour26:I also think I can help to provide reliable answers and explanations to questions and also propose some helpful questions. let questions be encouraged, instead of writing the whole chemistry textbook here, while time is now very short for that. Well I can be of service from now till 5th of January but will still be visiting this thread occasionally. nice work guys. I Rep Industrial Chem. (uniben) wishing all the jambites success |

icecalm:Mg2+ + 2e- = Mg . . 1mole=2F, xmole=10F . . Cross-multiply, 2x=10, x=5mole mole=mass/molar mass . . 5=m/24 . . M=24*5 . . Mass of Mg=120g . Solved it without biro and calculator . . M i ryt? |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 5:00pm On Dec 24, 2014 |
mesoade:yeah very correct |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by adebayour26: 9:24pm On Dec 24, 2014 |
icecalm, am really grateful for your efforts. I understand that typing could be a bit difficult, judging from d fact that there's no time. The best thing is if people could be asking questions often. |

Pls,what is the difference btw a pure subtance and an impure substance |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by mathefaro(m): 10:02am On Dec 25, 2014 |
ifeoluwaobiwale:an impure substance is a mixture of the pure substance and some other impurities. More so, a pure substance has a definite boiling point while an impure substance boils over a range of temperature, just as you know that impurities elevate the boiling point while it lowers the melting point of substances. On a final note, a pure substance while produce just one spot on a paper chromatogram since it contains just a single entity. Merry Christmas to y'all |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by mesoade(m): 10:54am On Dec 25, 2014 |
ifeoluwaobiwale:d diff. Is just impurity . . . |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 2:02pm On Dec 25, 2014 |
adebayour26:okay |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 2:29pm On Dec 25, 2014 |
QUESTION after using a white bleached straw hat for some time, Musa noticed his hat is turning into yellow. what could be the cause (a) His hat is bleaching again due to sun rays (b) His hat was bleached by chlorine. (c) The Chloride in His hat is reducing (d) The bleaching agent used to bleach His hat is undergoing reduction. (e) The bleaching agent used to bleach His hat is undergoing oxidation. |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by mesoade(m): 10:00pm On Dec 25, 2014 |
icecalm:i think it's C ,because chlorine bleaches by oxidation and for the colour to reverse,it means it's reducing |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by bolaji3071(m): 10:10pm On Dec 25, 2014 |
B |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 10:27pm On Dec 25, 2014 |
mesoade:you are wrong, but right in the explanation that chlorine bleach by oxidation and reduction is reversing it effect of bleaching. and what could cause such reversion would be a special reagent, but Musa's hat was only worn on the head by him occasionally/ often |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 10:31pm On Dec 25, 2014 |
bolaji3071:still wrong |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by sammyomotola: 11:54pm On Dec 25, 2014 |
D |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by mesoade(m): 8:22am On Dec 26, 2014 |
icecalm:he's wearing it in the head,then i think the sun bleaches(responsible for the reduction) it |
Re: Nairaland Jamb Tutorial Centre {chemistry Thread} by Nobody: 9:58am On Dec 26, 2014 |
mesoade:still wrong |
