johnpaul1101: gudday everyone, plz i have this question:
(1)Does the sun moves? If yes, How?
(2)can shadow be called an object or the image formed? This is my number08137456323

Dats true, d sun doesnt move, nd shadow is an image cast by an object

Edis4christ:

Thanks a lot, but d argument here is that sun moves around it's axis and that shadow is an object

4 gurusz...when da electronegative differenc btw 2 bonded elements iz zero....dat means ....

The compound formed by the two elements is non-polar...hence a diatomic non-polar molecule is formed

gud...bt preferably non-polar covalent bond iz formd

.....tetrahedral......trigonal bipyramidal....octahedral

...1..tetrahedral avin lone pair of zero and bond pair of 4,....2...trigonal bipyramidall...avin a lone pair of zero and a bond pair of 5.....3....octahedral avin a lone pair of zero and a bond pair of 6

Ur i is wrong Xef4 is square planar

Conc.H2SO4 is 98% pure.if its density is 1.80g per cm3,what z its concentration in mol/dm3?
A.18.0
b.18.2
c.18.4
d.18.6

I dnt get it,pls ans d que@buzyguy

Ok,using formula: c=(10pd)/M,where c z molarcönc,p z 98 nt over 100 o only 98,d z density in g/cm3 wich z 1.80,M z molarmass in g/mol.substitutn d valuez.theoretically make 98/100 of 1.8 then convert to g/dm3,afta d molar conc wld be calculated.

Lets try dis

a resistor of 0.68kohms, when connected in a eletrical circuit, dissipates a power of 85mW. Calculate
(i) the potential difference developed across it and
(ii) the current flowing tru it

Hy emmyeuler...... U misinterpreted my statement d oda day nd u got me baned for 4days...... Wat i meant d oda day by 'diz ur quesn .........' was dat diz ur quesn was reli tof buh u miss interpreted it nd u even complained on diz thread nd ui thread getin me baned pls dnt jump into d meanin of words lyk dat mayb coz ure a bit aggressive or wateva, try nd calm down to undastand d meanin of d word nd y d pasin sed so!


Diz ur new quesn are advanced quesn oooo, try nd folow d syllabus nd nt goin too far into advanced tinz coz ol diz myt nt even cum out in ur putme buh am nt sayin its irrelevant buh its too advanced! Tnx

@Johntosyne.....i am sorry for the other day..... but valence shell electron pair repulsion theory and also chromatography calculation came out last year in oau p-utme....its always good to read extensively because u never can tell

Morning all,check this...The simple sugars,glucose and fructose can be distinguished by reaction with.....a)Tollen's reagent b)Fehling's solution c)Benedict solution d)C-naphtanol in concentrated HCl..........I've been here a y buh nobody was posting or anything so I tut u guys are no more coming bck buh nw that yu'r bck,I gat heap of physics and chemistry for u guys if u want biology too,its at ma disposal..Luv u all.

@LABADINHO...C NAPHTOL IN HCL IS THE ANSWER....BECAUSE GLUCOSE AND FRUCTOSE REACT SIMILARLY WITH FEHLINGS,BENEDICT AND TOLLENS REAGENT....DESPITE THE FACT THAT FRUCTOSE IS A KETOSE IT HAS A MECHANISM OF GIVING POSITIVE TEST FOR REDUCING SUGARS....!

diz ones are in d syllabus buh its gud to read wide tho buh nt too wide

Luvly one der emmy,u'r correct.

Someone should pls list advanced topics needed 4 post ume that are nt in Jamb syllabus.....
