What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?
Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of N_{2} molecule is as follows.

Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Select the correct answer. When an atom in a reactant loses electrons, what happens to its oxidation number? A. Its oxidation nu
vfiekz [6]

Answer:

C. Its oxidation number increases.

Explanation:

  • <em><u>Oxidation is defined as the loss of electrons by an atom while reduction is the gain of electrons by an atom</u></em>.
  • Atoms of elements have an oxidation number of Zero in their elemental state.
  • When an atom looses electrons it undergoes oxidation and its oxidation number increases.
  • For example, <em><u>an atom of sodium (Na) at its elemental state has an oxidation number of 0. When the sodium atom looses an electrons it becomes a cation, Na+, with an oxidation number of +1 , the loss of electron shows an increase in oxidation number from 0 to +1.</u></em>

Can a substance be a Lewis acid without being a Bronsted-Lowry acid?<br> Please argue on it
makkiz [27]

Answer:

Yes. Since for a substance to be a Bronsted-Lowry acid they have to be able to donate protons, and to be a Lewis acid a substance would have to accept electrons, there are substances which cannot donate protons but can accept electrons.

Explanation:

Hope this helped!
