Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
The shorter the wave length the more energy. The further the electron falls, the more energy that will be emitted and the shorter the wavelength.
What is the simplest formula for nitride?
The chemical formula for a nitride ion is N-3.
Element that completes n3?
Ne (neon) completes n3.
What are the conditions for the neutralisation reaction?
N1*V1 = N2*V2 (where N1 & N2 are the normality of respective acid or base while V1 & V2 is their respective volume).
How many liters of NH3 are needed to react completely with 30.0 L of NO at standard temperature and pressure?
The balanced equation for the reaction of NH3 (g) with NO (g) is the following 2NH3 (g) + 3NO (g) ---> 2.5N2 (g) + 3H2O (l). Since at constant temperature and pressure, moles of gas (n) and volume of gas (L) are proportional. n1 / V1 = n2 / V2 so V2 = n2 * V1 / n1 where n2 = 2, n1 = 3, and V1 = 30.0 L. This means that V2, or the volume of NH3 (g) needed is 20.0 L.
Write a program that generates the Fibonacci series up to 200?
class Program { static void Main(string[] args) { int n1, n2, n3,i; n1 = 0; n2 = 1; for (i = 1; i <= 20; i++) { n3 = n1 + n2; if (n3 <= 200) { Console.WriteLine(n3); n1 = n2; n2 = n3; } } Console.ReadKey(); } }
How do you add two numbers in oracle?

What is the pmf of trinomial distribution?
P(x=n1,y=n2) = (n!/n1!*n2!*(n-n1-n2)) * p1^n1*p2^n2*(1-p1-p2) where n1,n2=0,1,2,....n n1+n2<=n

What does Fortran statement If left paren If left paren 2 times A comma Y Rt paren Rt paren 6 comma 5 comma 6 mean?
It is a three-way case statement. ( Arithmetic IF statement) IF(exp) n1,n2,n3 meaning go to n1 if expr < 0 ( value is negative) go to n2 if expr = 0 ( value is zero) go to n3 if expr > 0 ( value is positive) IF(expr1-expr2) n1,n2,n3 meaning go to n1 if expr < expr2 go to n2 if expr = expr2 go to n3 if expr > expr2 reference: Fortran 77 with 90 Applications for scientific and engineers second edition RAMA N.
