Hello,

Chemical equilibrium is the state of a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction. While a reaction is in equilibrium the concentration of the reactants and products are constant.

There are many examples of chemical equilibrium all around you. One

hi prince 

from joules law ohheatinh 

h=i^2RT

which indicates 

H/T =V^2/R

100=V^2/4

V^2=400

V=20

i hope you have got your answer .it should be noted that the rate  of the  heat is given and not just the heat .further convert the current I in terms v/r in the above equations

Hello there,  

In most of the exams,  the mass of typical elements,  those which has a higher atomic number,  is given in the exam but for the simple elements,  with a atomic number less than 30, and for popular elements,you should learn the  masses of such elements. 

Hope it helps. 

1.The angular node= l(azhimuthal quantum number).

2.Total nodes=n-1(principle quantum number).

Given:  3 angular nodes,then l=3. ;  3 Total nodes, then n-1=3.

l=3 means it is f- orbital and

n-1=3 solving this we get n=4. So 4th shell.

Finally the answer is 4f.
