u too,take dis one home.
What is d name gvn to d process whch a rxt rate is dcrsd by quickly lowrn d temperature

Nomski0: i knew it.


@mikebis, you're right.

9c one.
Mine turn.
What is d maximum concentration of chloride ions that cld exist in a 0.01mol/dm^3 solutn of a silver nitrate in contact with solid silver chloride?

drstan: Ss1-3..what happen during dark reaction in photosynthesis, .....ALevel, what is electron transport chain,and NADPH? (dnt mind my questions, dat my dpatment (BCH)

lol..guy na industrial chemistry i de do o,as 4 bio am partialy out buh nt all sha

Nomski0: Okay,
what is an azeotropic solution?

wow..its a solution that has a constant boiling point.
Am i korect*winks*

Nomski0: What is inertia

its a properties of matter by whch it continues in its existing state of rest or motion unless am external forces is applied.
Omg dis s.s.1 work menh,we are undrgraduate here maam..we nid strng questn,like d way ur beauty is so strng*winks*

Letz try dis IQ questn.
A scientist man was avn a laboratory pratical in his house,sudnly his wife call on him 4 dinner,nd dis man rush to tap nd wash his hand wt sponge nd soap.after dis man finish eatn,in nxt 20 minute,he died.
Wat kill dis man?

Well u all av a point.buh dis wat am xpectin
At low pressuse d molecules are on averagd far apart,dis means dat d forces btwn dem can not get to work easily,so they wanda arnd independently,like d molecules of an ideal gas.
Daz all

[quote author=I_am_Sylva]It is because gas molecules
have no attraction at
low pressure and high
temperature the
volume of the gas is
very high so that makes the
kinetic energy very
high. In this condition, the molecule cannot attract each other so they behave like a ideal gases[/quote]hmmmm

benbuks: Wot cud b d impossible condition need 2 determine d distance btw heaven and earth..?

c dis ma oga here sha,u wan spoil dis place wt crazy questn lol

Ikemsinachi: There will be a little argument here!

lol

Nomski0: At low pressures, following Boyle's law, the volume is high as pressure and volume have an inverse relationship. At large volume, the particle size of the gas becomes insignificant due to the massive spaces between the molecules. In this case real gases tend to behave like ideal gases.

hmmmm,u gat a point,buh nt all

Richiez: Nice thread!

ma oga is talkn i de stand*postrating 4 u ma oga*

u welkm dude.team uite.take dis 4 d introductn
write d equatn for d reactn btwn sulphuric acid and sodium azide

Odilop: at low pressure real gas have weak intermolecular forces

no

Ikemsinachi: I've been away since ystday night....jst saw d trend flowing!

I hail una oo

Ok, for ur qustion, gas molecules have no
forces of attraction and at low pressure this makes the
molecules not to attract each other and they
behave like a ideal gases.
NB: this is obtainable at high temp; and low pressure.
I rest my case!!

no

Why is it that at low pressure real gases begin to behave more like ideal gases?

Sammy Hoe: frequency of source? I think you missed out a word: change in 'sound' frequency of

An unknown compound
contains only carbon,
hydrogen, and oxygen.
Combustion of 7.50 g of this compound
produced 11.0g of carbondioxide and 4.50 g of water. How much C and H were in the original sample?


Good morning gurus[/quote]let me gv it a try,buh no abuse me if am wrng o.
Let d unknw cmpnd b x
usn equilibrium constant
ur product/reactant
kc=[11.0][4.50]/[7.50]
xo we av 6.6
there4 usn 6.6 to divd d molar mass of C nd H.
We av 6.6/12=0.55 for C
6.6/2 =3.3 for H

Mikebis: chai..na wa o,no 1 to do dis little clculatns

ok,here is d solutn
1.clculatin d rate constant usin
In a/a-x =kt
where In is stl d same as loge base x
a=10mol i.e initial conc
x=6mol i.e reactant mol
k=rate constant
t=10s i.e time
thr4..In 10/10-6 =10k
In2.5=10k
2.9=10k
k=0.29
2.calculatin d half life
T1/2 = 0.0693/0.29 =0.5290s
3.calculatin d rate of rxt
usn
R=kc
whr c=a-x
R=k(a-x)
=0.29-4
R=1.16mol/dm^3/s.
Dat all
