wel...he proved tha the valuet angular momentum for an electron(mvr) should be an integral multiple of that nh/2pi... where n is the principal quantum no.

 this G is the gravitational constant and its value is 
ang g is acceleration due to grvity and g= GM/R*R

One of the simple machines; a wheel with a grooved rim in which a pulled rope or chain will lift an object (more useful when two or more pulleys are used together such that a small force moving through a greater distance can exert a larger force through a smaller distance)

if you could type the question fully i think its easy to answer...its like a gobbledegook
|

well... its because as molality increases the moles of solute increases ...this is because Molality = Moles of solute divided by mass of solvent in kilogram..this increase causes the Vapour pressure to decrease..we know that boiling point is the temperature at which the vapour pressure is equal to the atmospheric pressure..thus only at higher temperature this happens which obviously causes the boiling poit to increase...

for a sparingly soluble salt the Ksp is derived by assuming a small amount will dissolve and yield ions according to its composition.The small amount that dissolves IS the actual solubility of the salt in moles/L.. soo since you have a value of 20 mg/L as the solubility of PbSO4 convert that to moles /L by dividing the grams of PbSO4/L
(20 mg/L = 0.02 grams/L ) by the molar mass of PbSO4 ( 207.2 + 32 + 64 = 303.2 grams/mole ) soo 0.02 grams /L / 303.2 grams/mol = 6.6 x 10^-5 moles/L = 6.6 X 10^-5 M as the actual solubility of PbSO4
Setting this in the Ksp relationship
Ksp( PbSO4) = [Pb+2][SO4^-2] a small amount of the insoluble salt ( 6.6 X 10^-5 M ) dissolved to yield 6.6 X 10^-5 M Pb+2 AND 6.6 X 10^-5 M SO4^-2 soo the Ksp = [6.6 x 10^-5][6.6 X 10^-5]
= 4.36 X 10^-9 ::::::.. using this Ksp one can determine what the solubility of PbSO4 is in a solution containing 0.01 M Na2SO4.
The .01 M Na2SO4 will ionize 100% to yield 2 x 0.01 M Na+ and 0.01M SO4^-2 soooooo the solubility of the PbSO4 ( x )is obtained by::
Ksp = 4.36 X 10^-9 = [Pb+2 = X ][total SO4^2 = X + 0.01 M ].
Because X is going to be very small compared to 0.01 neglect it in the
X+ 0.01 M term and the equation reduces to:::: 0.01X =4.36 X 10^-9
solving for X ::: X = (4.36 X 10^-9)/10^-2:::::: X = 4.36 X 10^-7 M
so in the presence of 0.01 M SO4^-2 the solubility of PbSO4 is reduced from 6.6 X 10^-6 to 4.36 X 10^-7 or PbSO4 is 15 times less soluble in the presence of 0.01M SO4^-2

actually colligative properties are studied for dilute solutions...
|
|
|
|
|
H(2)S atoxic gas with rotten egg like smell, is used for the qualitative analysis.If the solubility of H(2)S {hydrogen sulphide} in water at STP is 0.195m,calculate Henry's law constant.
|
|
|
|
|
ya.. Lowering of vapour pressure is a colligative property (Roults law)

yea ,, i am one of the cards appearing for physics olympiad...iwell if you are preparing for IIT-JEE that will do,,but a special preparation is needed for this and just try to solve as many problems you can from earlier question papers
|
|
|
|
|
so,,just try to be strong in the lessons you like the most in physics and be strong with basic formulas .. i think that will do pal
|
|
|
|
|
hi,k lets consider like this ... you cleared IIT -JEE without learning physics...k.. think what would happen if they call you for an oral interview ..i think they will surely consider your physics mark for consideration,
|
|
|
|
|
HI ,, as per my knowledge two subjects cannot make you clear IIT-JEE ..
