In order to protect underground pipelines and storage tanks made of iron, the iron is made the cathode of a voltaic cell through a process called Impressed current method which is a kind of cathodic protection.

There are two methods which belongs to cathodic protection

a) one is by connecting the base metal with a more reactive metal and making the more reactive metal anode which sacrifices itself protecting the base metal [Iron in this case] : This is known as Sacrificial anodization protection

b) the second method is : Impressed current method where the base metal is connected to a battery in such a way that it starts behaving as cathode. This method is used in the given problem

Different isotopes of the same element emit light at slightly different wavelengths. A wavelength in the emission spectrum of a
Inessa [10]

Different isotopes of the same element emit light at slightly different wavelengths, the minimum number of slits  is mathematically given as

N=1820slits

<h3>What minimum number of slits is required to resolve these two wavelengths in second-order?</h3>

Generally, the equation for the wave is mathematically given as

d\ sin\ (\theta\ m) \ = \ m\  \lambda

Where the chromatic resolving power (R) is defined by

R\  =\ \lambda\ / \ d \  \lambda

R = nN,

Therefore

\lambda_1 \ = \  (656.45)(1 \ * \ 10^{-9})/1mm

\lambda_1= 656.45*10^{-9}

and

\lambda_2= (656.27)(1*10^{-9})/1mm

\\\\\lambda_2= 656.27*10^{-9}m

In conclusion, the minimum number of slits is required to resolve these two wavelengths in second-order

N\ =\ \dfrac{\lambda}{m\ d\ T\ }\\\\

Therefore

N\ =\ \dfrac{656.45 \ * \ 10^{-9}}{2\ * \ (0.18*10^{-9})}

N=1820slits

Magnesium and iron are metallic elements. How does a mole of magnesium compare with a mole of iron? A mole of iron has more atom
grandymaker [24]

Answer:

They both have the same number of atoms

Explanation:

The number that indicates the amount of particles in a compound is the Avogadro's number (NA).

It does not matter the mass of compound we have, If we have 1 mol we will be sure that we are talking about 6.02×10²³ particles

6.02×10²³ represents the amount of atoms in twelve grams of 12-pure carbon and it is considered a reference to measure the amount of all kinds of substances present in a given system.
