Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of
A.
one atom of nitrogen and one atom of oxygen.
B.
two atoms of nitrogen and one atom of oxygen.
C.
two atoms of nitrogen.
D.
one atom of nitrogen.

Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.

The correct option is C.

Explanation:

Nitrogen gas has the chemical formula , which means that two atoms of nitrogen element combined to form nitrogen gas.

The combination of two atoms of element nitrogen produce dinitrogen atom.

Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.

2 atoms of nitrogen element

N + N =

the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
