If hydrogen atom is in an energy level represented by n=4,how many spectral lines are possible in its emission spectrum?
Ans) There is a formula for this i.e
[ (n2-n1+1)(n2-n1) / 2 ] So if acc. to your question n1=1 and n2=4 then the answer is 6
compound reacts with oxygen to form 2 oxide x and y. or analysis 1.535g of x yielded 1.365g of copper and 1.545g of y yielded 1.6 a.determine the chemical compound of x and y.b .
Phenol + HNO3(in prescence of sulphuric acid) --> 2-nitrophenol + 4-nitrophenol.

The ratio among the radius of cation and the radius of anion is known as Limiting radius.
What is piezoelectricity Piezoelectricity provides us a means of converting electrical energy to presume new geometric positions and mechanical dimensions of the substance are
