nodales r plains where probability of finding an electron is minimum its due to the revolution made by electrons in a specific direction that is in s-shell orbital they have spherical shape
in p-shell they r oriented around x-y plain/dz plain /y-z plain ...
so in p-shell is its not spherical there have the areas from which the electrons will not pass bcoz of there special orientation around specific axis........
thats make the nodal plain havin the minimum probability of finding an electron..............

1.an electron is moving in a circular orbit of radius 'r' makes n rotation /sec . Magnetic field produced at the centre is what???????

2.a long vertical wire carries a current in a upward direction how many neutral points are obtained in the given points??????????????????????

1.xpress variation in conductivity and molar conductivity of strong and weak electrolyte with dilution????????

2.y do some times we get abnormal molar mass of solute using coligative method..

3.define vent hoff factor for a) K4FeCN6 b) benzoic acid in benzene(if it dymerises)...

4.y do soln deviate frm ideal behaviour.

5.on mixing cyclohexane with ethanol what type of behaviour is expected and y?

6.electrolysis of aq.NACL gives h2 at cathode y ?

7. will the value of colligative property be the same in

a)1mol urea b)1 mol sugar

a)1mol sugar b)1mol NaCl.........

Q: There is a sphere with uniform volume charge density (non-conducting of course, duh!) A spherical cavity has been made inside it. Find the net electric field at the centre of the CAVITY.

Case I:

i.e. The centres of the sphere and cavity coincide.

(Hint: Symmetry – PRESENT)

Case II:

i.e. the cavity is to one side of the sphere.

(Hint: Symmetry – ABSENT)

wat is optical isomerism?

how its known that a compound is chemically active or inactive?

i want detail info abut:

can u xplain y?

give an example of negative deviation from raoults law from organic compounds...

and give reason for ur answer

wat would be the molality of a solution made by mixing equal volumes of 30% by mass of H2SO4 (density 1.28 gm/cm) and 70% by mass of H2SO4(density 1.610gm/ccm).

8.0575/100 KG OF GLAUBERS SALT. SALT IS DISSOLVED IN WATER TO OBTAIN 1dm(cube) OF A SOLUTION OF DENSITY 1077.2kg/m(CUBE) . CALCULATE THE MOLARITY ,MOLALITY AND MOLE FRACTION OF SODIUM SULPHATE IN THE SOLUTION....
