Swagalord18: it is correct
yep
EducationRe: Online tutorial in Physics, Chemistry, Maths for Jamb and pume by greatdavid1: 3:14pm On Jan 07, 2014
Swagalord18: according to Dalton's law,
total pressure = sum of partial pressures
so 752(total pressure) = 32(water pressure) + x(oxygen pressure)
x = 752 - 32 = 722mmHg(oxygen pressure)
p1V1/T1 =
p2V2/T2 (gas equation)
p1 = 722 mmHg
V1 = 500 cm3
T1 = (30 + 273)K = 303K
p2 = s.p = 760 mmHg
V2 = huh
T2 = s.t = 273K

v2 = p1V1T2/p2T1
= 722 x 500 x 273/760 x 303
=
426.78 cm3
P1 = 720 mmHg and not 722 mmHg......typographical error

In d below reaction,.what is d value of x?Cr2O7^2- + 14H^+ + xe^-=2cr^3+ + 7H2O
pls waht I need most is aw u get dat value,...xo ur workings is all I need
balance the charge at both sides.....
Total no of charge in the RHS=> +14 + (-2)= +12
total no of charge in the LHS=> 2 *(+3)= +6
: . RHS must be equal to LHS
i.e +12 + 6e^- = +6
x=6
thus, we have the equation as:
Cr2O7^2- + 14H^+ + 6e^-=2cr^3+ + 7H2O

Swagalord18: [color=grey]+yawns+ ......and thats the reason why the magnification is always 1.0, ..it neither magnifies nor diminishes, ....the object distance is 10, so the image distance will be 10, ....
Magnification = 10cm/10cm = 1.0, ....its that simple
[/color]
i agree with swagalord.......but the fact still remains that plane mirrors don't magnify...

EducationRe: Online tutorial in Physics, Chemistry, Maths for Jamb and pume by greatdavid1: 8:55pm On Jan 05, 2014
aysuccess99: this looks like a further maths question, but I will do answer it.
solution
x=4t^4-3t^3
V=dx/dt=16t^3-9t^2
therefore, V is velocity, and it is 16t^3-9t^2
and acceleration=velocity/time
a=dv/dt
a=48t^2-18t
therefore, when t=3seconds, acceleration would be.
a=48(3)^2-18(3)
a=48(9)-18(3)
a=432-54
a=378m/s^2
therefore,:::::::: the acceleration after 3seconds is 378m/s^2
to the bosses and ogas in the thread, my answer is subjected to correction. Thanks.
correct

......Let me again pinch u all with a good chemistry question

Balance the following REDOX REACTIONS

1)[CLO(3)]^(-1) + Zn ---> Cl^(-1) + Zn^(+2)
i belive,you forgot to tell us the medium we should use....but i'll use acidic medium..
Cl03^-1 => Cl^- ( reduction)
zn => Zn^2+ (oxidation)
Cl03^-1 + 3H + 6e^- => Cl^- + 3OH
Zn => 3Zn^2+ + 2e^-
finally: Cl03^- + 3H^+ + 3Zn => Cl^- + 30H^- + 3Zn^2+

U can as well use dis as a shewing stick,.....The sides of a regular polygon are produced so that evry pair of exterior angle and interior angle is ratio 1:4. Calculate
a.the size of an exterior angle
b.number of sides of d polygon
it has been some time now i've been contemplating over this question since you posted it initially.......but within my own knowledge, i resulted into this:
let exterior angle be x and interior angle be 4x.......then x + 4x = 180.....
X=36 degree
thus,
1)size of exterior angle=36
2) 2n-4)90/n=144
n = 10
