The element vanadium had a line with a wavelength of 318.5 nm in its emission spectrum. What is the frequency of this line
Hunter-Best [27]

The frequency of this line of vanadium  is 9.38 x10 ^14 Hz.

Emission spectrum shows how the electron of an atom goes or moves  from a higher to a lower energy level.

Now The energy of a photon is given by

E = hc/λ

where  

h = Plank's constant =  6.626 x 10⁻³⁴ J s

c = speed of light=   3 x 10⁸ m/s

λ = wavelength =  318.5  x 10⁻⁹ m  

Solving

E =  (6.626 x 10⁻³⁴ J s x 3 x 10⁸ m/s)  / 318.5  x 10⁻⁹ m

E =6.2166 x10 ^-19 J

Also, we know that energy is related to frequency by the equation

E =hf

Where;

h = Planks's constant

f = frequency of photon

Making frequency subject of the formulae

f = E/h

f =6.2166 x10 ^-19 J/  6.626 x 10⁻³⁴ J s

f =  9.38 x10 ^14 Hz

Old aspirin exposed to moisture often smells like acetic acid (vinegar). When aspirin is heated in boiling water, it decomposes
Anit [1.1K]

Explanation:

Vinegar like smell is given off by aspirin when we tend to heat it in boiling water. The main cause of this vinegar like smell is due to the formation of acetic acid and a phenolic acid upon heating of aspirin.

As a result, it gives a positive test when treated with ferric chloride, that is, FeCl_{3}.
