naturalwaves:Yeah, he's very correct bro because if (a + b) log x = log b, then log x (a + b) = log b and x (a + b) = b. (log 10 cancels each other) Having said this, I thin the only logical solution to this is the graphical method. One has to draw a graph of y = 2 x and y = 4x on the same axis. 3 Likes |

Preboy:when we say electronic configurations, we mean The arrangement of the electrons(electronic) which could either be on shell shells (k,l,m,n) or on orbitals(s,p,d,f). You need to puree that there's a difference between shells and orbitals. The maximum number of atom a shell can hold is given by the formula 2n2 where n is the energy level out let's say the position of the shell, as a result of that, the first shell, whose n=1, can only contain 2 electrons, subsequently, the L-shell can contain 8 electrons and so on. Therefore when writing electronic configurations, subsequent shells must be filled before going to the next shell. Then each shell is further subdivided into orbitals and sub-orbitals which can only contain 2 electrons spinning in opposite directions. Therefore we can say shell contains orbitals on which the electrons evolve round the nucleus. S orbitals can hold 2 electrons, p orbitals can hold 6 electrons(3 sub-orbitals containing 2 electrons each), d-10 electrons(5 sub orbitals) and f-14 electrons. K shell has just one s orbital since it can contain just 2 electrons. The L shell which can hold a maximum of 8 electrons has 1 s orbital(2 electrons) and 1p orbital(6 electrons) . So for calcium, whose atomic number ( no of protons and no of electrons) is 20, the electronic configuration in terms of: Shell: 2,8,8,2 Orbitals: 1S22S22P63S23p64S2 As you can see, it has 4 shells(period 4) and the valence electrons(electrons in the outermost shell) are 2(group 2) Wow! That was such an epistle. I hope somebody would gain something from this 3 Likes 1 Share |

Kunlexic:in addition, evaporation takes place only at the surface while boiling takes place in all parts of the liquid, more so, evaporation does not really require heat or an increase in temperature to take place although an increase in temperature will increase the rate at which it occurs, but boiling on the other hand requires a specific amount of heat/temperature 1 Like |

Preboy:C-just before hitting the ground because when a body is thrown vertically upwards, it's speed gradually decreases until it gets to the maximum height where it's speed is zero but as the body starts moving downwards, it accelerates, increasing it's speed until it gets to its maximum magnitude just before hitting the ground where the speed goes back to zero (body not moving anymore) |

omoadeleye:we already know that the numbers in the powers of 2 are 1, 2, 4, 8, 16, 32, 64, 128 and so on, but for us to split 59, we should know that we can only use numbers less than 59, so we started from 32, adding the smaller consecutive powers of 2 until we get 59. but like I said earlier, it's beyond the scope of UTME, so don't expect this kind of question 1 Like |

Hey guys, someone just asked me a question and I don't know ťhe correct answer for him. He asked if it's possible to get admission through both UTME and DE considering the payment of acceptance fee and clearance process. |

sheddyboy:First and foremost, you need to know that this is not within the scope of utme, then onto the question, To convert 59/64 to base 2, split 59 to span across the multiples of 2, you're gonna get (32 + 16 + 8 + 2 + 1)/64 That will give: 32/64 + 16/64 + 8/64 + 2/64 + 1/64 ==> 1/2 + 1/4 + 1/8 + 1/32 + 1/64 ==> 2-1 + 2-2 + 2-3 + 2-5 + 2-6 ==> therefore, 59/64 = 0.111011(the zero between them is for the missing 2-4 in the expansion. I hope this helps. To the mods, I'm sorry I had to jump in, I was just bored. 1 Like 2 Shares |
