uses of nitrogen

Hi friends!!!

Can you tell me what is air?

Air is a mixture of many gases like nitrogen, oxygen, argon, carbon dioxide etc.


Let us learn about uses of nitrogen.

Nitrogen can be found in both animals & plants.

Nitrogen is used in light bulbs in place of argon.

Nitrogen is used to pack foods because it contains oxidation of foods to maintain their freshness.

Nitrogen is essential in the manufacturing of electronic parts like, transistors, integrated circuits and diodes.

Nitrogen is very important for pollution control

Nitrogen is used scientific research. Etc

formula for mass

Let us learn about Mass.

The mass number (A), also called atomic mass number or nucleon number, is the total number of protons and neutrons in an atomic nucleus

A mass formula is an equation or set of equations in physics which attempts to predict the mass or mass ratios of the subatomic particles.

formula for mass 1 u= mass of ¹²C₆ atom / 12

In our next blog we shall learn about mass moment of inertia I hope the above explanation was useful.Keep reading and leave your comments.

ammonium bromide

Let us learn about ammonium bromide

Ammonia bromide, NH4Br, is the ammonium saltiness of hydrobromic dissolver. The chemical crystallizes in whitened prisms, possessing a saline discernment; it sublimes on evaporation and is easily explicable in facility. On exposure to air it gradually assumes a chromatic variety because of the oxidization of traces of bromide to element.

Ammonium bromide is misused as a beam retardant especially for chipboard. It is victimized in manufacturing photographic chemicals and emulsions.

examples of renewable resources

Let us learn about examples of renewable resources

Few elemental renewable resources much as energy power, unprocessed thing, timber, and biomass must be old with repair to refrain prodigious the power to replenish them. A invigoration interval provides a systematic way of scheming renewability.

microscope magnification

Let us learn about microscope magnification

The linear magnification m, for the image formed at near point D, by a simple microscope can be obtained by using the relation

m= v/u = v(1/v - 1/u) =(1 – v/f)

Now according to our sign convention, v is negative, and equal to the magnitude of D. Thus, the magnification is

m = (1 + D/f)

Note that

m = h’/h

Where h is the size of the object and h’ is the size of the image. This is also ratio of the angle subtended by the image to that subtended by the object, if placed at D for comfortable viewing. The magnification m if the image is at infinity is

m = D/f

This is one less than the magnification when the image is at the near point. But viewing is more comfortable and the difference in magnification is usually small this is why the image is generally assumed to be at infinity.

diatomic molecule

Let us learn about diatomic molecule

Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive charge. The extent of polarity in such covalent molecules can be described by the term Dipole moment.

Dipole moment can be defined as the product of the magnitude of the charge and the distance of separation between the charges.

It is represented by the Greek letter 'm'. Mathematically it is equal to

dipole moment (m) = charge (e) x distance of separation (d).

It is expressed in the units of Debye and written as D

(1 Debye = 1 x 10^-18e.s.u cm)

Dipole moment is a vector quantity and is represented by a small arrow with tail at the positive centre and head pointing towards a negative centre.

Formula Molecular

Let us learn about Formula Molecular

Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound.

An expression which states the number and type of atoms present in a molecule of a substance.

A formula in which only the elements and number of atoms of each element are shown, e.g. C5H12

The mass of an atom of an element is called its atomic mass. The unit of atomic mass is any form of a mass like milligram, gram.Molar of a solution is defined as the quantity of gram-moles of solute softened in 1 liter of a solution. Molecular is as the grouping of atoms. A molecular is a combination of atom. Under the normal condition the elements are present in free state of an atom. The molecular mass of a matter is the calculation of the atomic masses of all atoms in a molecule of the substance.

A molecular shows all the physical and chemical properties of that matter. Molecules can obtain by same or different combination of elements.

Molecule formula is related to empirical formula.

Molecule formula = n * empirical formula

Where

n= (molecular mass / empirical formula mass)
