hey guys my birthday falls in the month of cold and chilly

october..............and i am very fortunate to be born on 3rd day of diwali!!!!!!!!!!great isn't it????????

thats why i celebrate it in diwali every year........

really cool vignesh..................

thank you all...........

you are absolutely right...............but what about gases?

58+2=60..................

wait wait..........................

i am here....take this..50+2=52

sir..................how the active masses for gases are expressed? is it in partial pressures?

please tell me more about this..................

please........................

please...............................

hi aatish,

please tell me how you did it.........i am sorry the answer given here is

5.789*10^-14 N^-2m⁴

acc to bohr...... angular momentum = integral mutiple of a constant h/2pi.......

i.e. mvr=nh/2pi.where m=mass of e v=velocity r=radius of the orbit n =an integer called the principal quantum number and h=plank's constant.

rearranging the above eqn,,,,,,

mv*2

r = nh.

i.e. momentum * circumference = nh.

in other words the angular momentum of an electron in an atom is quantised and can have values h/2 pi, h/3pi, h/4pi........nh/2pi.

are you getting anything from it......?

if no please do tell me......

a sardar gives dictation test for students, last bench student says "we are not able to hear you sir," sardar said " ok , i will write on the board!!!!"

gud one guys............

howz this..........

child 1:- mere papa bahut dorpok hain.......

child 2:- why?

child 1:-jab bhi road cross karte waqt mujhse kehete hain "beta mere ungli pakad ke rakhna..........chodna nahin........"

the ammonia in equilibrium with nitrogen-hydrogen mixturein the ratio 1:3 at 673K and a pressure of 4*10⁶Nm^-2 is 20% by volume. calculate k_p-(equilibrium constant in terms

of partial pressure)

thank you pathfinder........

and thank you shubhayan.....i regained my confidence......

hey umang.......according to my knowledge E is equivalent mass and i think the equation is multiplied by 1000 if the volume is given in cm^3.if the volume is given in dm³ then we need not multiply by 1000........

am i correct?

thank you all

please tell me more about law of mass action in chemical equilibrium.........

hi,

here is an direct formula

normality=(x% * density *10) / equivalent mass.

please do tell me if it is wrong

.............

pls answer this.....

three bodies are initially at the three vertices of equilateral triangle of side A. three bodies are moving with same speed and always directing towards one another. what is the time interval in which they meet?
