First, I want to explain that 1 mole of something basically means 6.02 x 1023 units of that thing. For example, 1 mole of eggs means 6.02 x 1023 eggs. Next, an oxygen atom is just represented by the symbol "O". An oxygen molecule, however, is represented by "O2", which means 2 oxygen atoms are joined together by a bond. Therefore, 1 mole of oxygen atoms means 6.02 x 1023 O 's, while 1 mole of oxygen molecules means 6.02 x 1023 O2 's. They're quite different.

We know the atomic masses of nitrogen and oxygen - 14.0 grams and 16.0 grams respectively (found on any Periodic Table). Because they are both diatomic and form two atoms in one molecule, then oxygen will outweigh nitrogen.

They both have the same amount of molecules.

They both have 6.02214179*10^23 molecules.

(which is the number of Avogadro)

How is the molecular formula NO different from the molecular formula N2O?

A single nitrogen atom can be chemically reactive while a nitrogen molecule is relatively stable and tends to be faf more inert. A nitrogen molecule also has twice the mass of a nitrogen atom.

Why in a water molecule is the oxygen atom bigger then the nitrogen atom?

First of all, there is no nitrogen in a water molecule. A water molecule consists of one oxygen atom combined with two hydrogen atoms. Also known as H2O. However, it is also true that an oxygen atom is slightly bigger than a nitrogen atom. Oxygen has one more proton, and one more electron than nitrogen does. Neutron quantities vary, since there is more than one isotope of both oxygen and nitrogen.


Why is the bond between hydrogen and oxygen in a water molecule is more polar than the bond between hydrogen and nitrogen in a ammonia molecule?

Oxygen has a higher electronegativity than nitrogen does, so when sharing electrons with hydrogen, the sharing is more uneven in the case of oxygen than it is with nitrogen. Oxygen, in other words, will attract electrons more strongly than nitrogen does and therefore will wind up with a more negative charge (hydrogen, which supplies the extra electrons to the oxygen, has a correspondingly higher positive charge).


What best describes the difference between the formulas for nitrogen monoxide and nitrogen dioxide?

Nitrogen dioxide has one more atom of oxygen per molecule than does nitrogen monoxide.


What is The molecules of nitrogen monoxide and nitrogren dioxide differ by a multiple of the mass of one oxygen is explained by?

Nitrogen monoxide is one nitrogen molecule (atomic weight 14) combined with one oxygen molecule (atomic weight 16). The atomic weight for NO is (14 +16 =) 30. Nitrogen dioxide is one nitrogen molecule (atomic weight 14) combined with two oxygen molecules (atomic weight 16). The atomic weight for NO2 is [14 + (2×16)] = 46. Nitrogen also forms a few more stable oxides; N2O Nitrous Oxide (Laughing Gas), NO3 Nitrogen Trioxide, and N2O5 Di-nitrogen Pentoxide (Nitric Acid Anhydride). H_AMMER


How oxygen and nitrogen can be extracted Also include their uses?

Oxygen is more electronegative and so a better electron acceptor. Nitrogen as a gas is a triple bonded diatomic molecule and very unreactive this way.


Why can't we use nitrogen the way we use oxygen?

Oxygen is more electronegative and so a better electron acceptor. Nitrogen as a gas is a triple bonded diatomic molecule and very unreactive this way.


Does nitrogen weigh more than air?

No. Nitrogen is slightly less dens than air. The density of a gas is directly proportional to its molecular mass. Dry air is 78% nitrogen, 21% oxygen. Nitrogen has a molecular mass of 28 AMU. Oxygen has a molecular mass of 32 AMU. This makes air just a bit denser than pure nitrogen.


Is nitrogen a molecule and why?

No because it is a single atom, like oxygen. A molecule/compound is more than one atom connected together like water.


A molecule is said to be organic if it contains?

An organic molecule is a molecule and that contains carbon atoms that are connected to hydrogen, oxygen or nitrogen atoms. Glucose has carbon, hydrogen and oxygen atoms so it is organic.


Does water have more hydrogen or oxygen in it?

By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
