Answer:
The answer is D.
Explanation:
Intermolecular force are negligible
When the distance between molecules decrease,
the attraction or repulsion become greater
Answer:
2H2 + O2 -----> 2H2O
Not sure about the second question though.
<h2>Ionic bonds result from transferring of electrons</h2>
Explanation:
- Ionic bonds result from transferring of electrons.
- An ionic bond is also referred to as an electrovalent bond.
- The main reason for the formation of the bond is an electrostatic attraction between oppositely charged ions that are cation and anion in a chemical compound.
- The formation of such bonds occurs when the valence (outermost) electrons of one atom are transferred to another atom or the loss of electrons from one atom and gain of electrons of another atom.
- The atom that loses the electrons forms cation that is a positively charged ion.
- The atom that gains electrons forms an anion that is a negatively charged ion.
