emmyeuler1: we were told to find the current flowing the primary winding

oh fanksz...mayb na direct proportionality i dey use...wetin b ur 2go id

emmyeuler1: @kendzyma....for a transformer, Ns/Np=Vs/Vp=Ip/Is this is because I &V varies inversely in P=IV....Hence, 10/3=10/Ip therefore,Ip=3A

hehe...is it d current in d primary stuff we wer told to find or d secondary?cnt find my question

idoghor luck: 100g of water does not mean 100cm3 of water. 5% by wt. Means 5g in 100cm3 of water. Then your mass conc of acid = 0.05g/cm3 is not the same as= 50g/dm3. If you are converting from gram to kilogram, from cm3 to dm3. Just an observation oh.

heheh...hw u get 0.05g\cm3...wen gram conc iz always in dm3..and we wer given in cm3...so na simpl conversion nw...100cm3=5g...so 1000cm3 will b....work dat out..i guess u used 1dm3 to work it instead of 1000cm3

emmyeuler1: @kendzyma...ur working is absolutely correct....deltaG=-nFE is the correct eqn to be used...where n=number of electrons transfered,deltaG=free energy change,F=faraday constant and E=electrode potential of the cell....u re correct!

chai..and me don see dis formula b4 4 chem o...i was even still lukin for entalpy ,entropy chang and temperatur....caus i thought free energy calculation ar always accompanied by all diz...bt i waz rng...fanks and lastly...dat transforma stuff in phy...i workd d current repeatedly...bt all i get iz 33.3....bt peopl said na 3A....still confusd hw dey go dat...or voltag frm d mains iznt primary voltag?pls explain 4da

emmyeuler1: @Kendzyma Dis is wat i reason..5% by wt. H2SO4 means 5g of acid dissolved in 100g of water.....But,100g of H20=100cm3 of H20..mass conc of acid=0.05g/cm3=>50g/dm3....but molarity=mass conc/molar mass....hence,molarity=(50/98)mol/dm3=0.510mol/dm3....

..waw fanks...i tnk sm1 1nc postd hw to solv molarity bt i dnt put much attention to it.aniwayz tanks......ehehn...and dat reduction potential stuff..wen i workd it..na 5.79kj i got asin....0.012-0.042=-0.03v......sinc na 2 electron...we av 9650*2*0.03=-5790.....=5.79kj...na dat dai i just tnk of dis..bt avnt com accrosz diz b4..so do u av d idea?caus m nt sur of wat i workd

emmyeuler1: @kendzyma.....let the number of protons=x and no. of neutrons=1.5x....therefore, 1.5x+x=120 2.5x=120 x=48 but the ion has a charge of +3......hence,its number of electrons=48-3=45

oh fankz..wat of d molarity

still amuszd at diz heart shakin scores i dey see for nairaland.. ,...i won no sm ansaz for dat chem ooo....especialy dat molarity.....and num of electron in da element with a charg of +3(na periodic table i tak draw dat day b4 knoin na 42 oo...and nt eveb sur its d ansa)...i guess emmayeula,profchris,xkid and oda scienc student would elp wit diz

emmyeuler1: omo but u deal with d physics well ooo.....85 and chm 67...

hehe...u tink say i no see hw u murderd d bio...leavin oau with no choic dan to giv u 80

shakur07: ma potential coursemate ** ao u dey nah **

i dey oo....cut off don put us for wayoo oo...ASUU should av strikd yrz bak...y nw,...d tin dey delay tinz wela..kipin ops high

Uricas: For those of you that are opting for biochm,i wil advise u to revise your futher math 'cos i see dat u didn't do math in your subject combination but whether u lyk it or yes u wil do rigorous math in yellow house for complete two session.

chai!...tell me its a lie o...dat i thought i don leav 4damath 4 life..omo wer i go start nw

emmyeuler1: ....according 2 dolphineyes,he said people are seriously buying change of course form in o.a.u(#1000) at the admissions office....

hehe....chang of cours ke? Abi dibu don enta oau system ni...well all iss well (dat ends well)...praying tnz sur pass nw

emmyeuler1: me na 263 i get.wetin u get 4 jmb?

u blastd it o.na 210 i get 4 dibu....does oau giv oda courses? Even with an agg of 225?

emmyeuler1: kendzyma wetin u blast 4 pjamb?

hehehe...blast ke...na 240 Oooo...if i no na inglish go affect me...i would av read d whol dico eng 28,chem 67,phy 85,bio 60..lolz...aniway...me dey opt for biochem o(sec choic).u nko...

[quote author=x-kid2000]lols but biochemistry aspirants on this thread is fewer.[/quote]heheh....biochem tinz here oooo...i pray d cut off favourz moi

[quote author=x-kid2000]lols but biochemistry aspirants on this thread is fewer.[/quote]heheh....biochem tinz he oooo...i pray d cut off favourz moi

guyz....need a slim tokunbo ps2 badly...bt dnt no d price...pls if ani1 as d idea of d price...pls tell me and if u also wana sell urz pls notify and dats if u stay in ibadan....tanks.
