What is the molecular formula for nitrogen?

-The chemical formula for nitrogen as an element is ‘N’. -The chemical formula for nitrogen gas is ‘N2’. Complete answer: Nitrogen is a chemical element whose atomic number is 7. It is the lightest member of group 15 of the periodic table which is often called the pnictogens.

What is N2 in chemistry?

Nitrogen is the chemical element with the symbol N and atomic number 7. At standard temperature and pressure, two atoms of the element bind to form dinitrogen, a colourless and odorless diatomic gas with the formula N2. Dinitrogen forms about 78% of Earth’s atmosphere, making it the most abundant uncombined element.

What is the Lewis structure of nitrogen?

The N2 Lewis structure has a triple bond between two nitrogen atoms. According to the octet rule, nitrogen atoms need to bond three times. The N2 molecule is diatomic, meaning that two atoms of the same element are connected in a pair.

Which is the correct formula for Dulong Petit’s law?

By Dulong-Petit’s Law, Atomic mass × Specific heat = 6.4 (Approx.) ∴ Approx. atomic mass = 6.4 / Sp. heat = 6.4 /0.03 = 213.33 ∴ Valency = approx. atomic mass / equivalent mass = 213.33 / 69.66 = 3.06 Now, corrected atomic mass = Equivalent mass × valency = 69.66 × 3 = 208.98 u Ans: Hence the valency is 3 and its atomic mass is 208.98 u.

How to calculate atomic mass by Dulong Petit’s law?

In previous articles, we have studied Cannizzaro’s method and law of isomorphism method to determine atomic mass. In this article, we shall study to calculate atomic mass by Dulong Petit’s law. The amount of heat required to raise the temperature of one mole of an element from 287.5 K to 288.5 K is called specific heat of the element.

What is the molecular weight of molecular nitrogen?

NCI Thesaurus (NCIt) Nitrogen appears as a colorless odorless gas. Noncombustible and nontoxic. Makes up the major portion of the atmosphere, but will

What happens to nitrogen in a refrigerated container?

Nitrogen, refrigerated liquid (cryogenic liquid) appears as colorless odorless liquid. Very cold. Contact may cause frostbite. Nontoxic. Under prolonged exposure to heat or fire the container may rupture violently and rocket.
