Optimist1998: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 |

Genius101: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. |

Optimist1998:. Abt d sucrose... Its in d txt book.. I think he made it up |

Optimist1998: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 |

Optimist1998:in the case of the unsymmetrical alkane is called wurtz reaction where alkane is formed from the rxn BTW an haloginoalkane and sodium |

Re: UTME 2017: Thread For Science Jambites by felix00(m): 2:17pm On Apr 25, 2017 |
Genius101:I think for it to serve as a wateva mirror it must be enlarged and erect.. So there is only one spot u get dat kind of combo I.E btw the pole and principal focus of the mirror. |

A body of mass 8kg is connected to a body of mass 5kg with an inextensible string passing over a frictionless pulley.Calculate the force of friction between the 5kg mass and the horizontal table if the 8kg mass accelerated cowards at 4.5m/s^2. (g=10m/s^2) |

felix00: You're right. Between F & P the Image is formed behind the mirror. Hence, it is —Virtual. —Since it is virtual, it must be erect. & —Magnified. |

A plane can travel with a speed of 80km/hr with respect to the air. Determine the resultant velocity of the plane (magnitude only) when it meets a 1)10m/hr head wind 2)10m/hr tail wind 3)10m/hr Cross wind 4)60m/hr cross wind |

who have reprint his/her own jamb slip for the mock |
Re: UTME 2017: Thread For Science Jambites by Nobody: 7:46pm On Apr 26, 2017 |
Godhead4:✅Head wind opposes the motion of the plane, resultant velocity = 80-10 = 70km/hr ✅Tail wind from behind= 80 + 10=90km/hr ✅10km/hr crosswind (Pythagoras rule) = √(10²+80²) =80.62km/hr ✅60km/hr crosswind(thesame method above) =100km/hr |
