Particles as small as atoms exist.
Answer :
Example of polar covalent molecules H-O-H(water), ammonia
Explanation:
The presence of intermolecular Hydrogen bonding makes the boiling point of water unexpectedly high, and the polar covalent nature makes it dissolve polar solute/compound
Answer: AgCl
Explanation:
When the reaction takes place in which the sodium chloride is reacted with silver nitrate then the products formed are sodium nitrate and silver chloride.
NaCl(aq) + AgNO3(aq) ⟶ NaNO3(aq) + AgCl (s)
This reaction is known as precipitation reaction in which the white precipitate of silver chloride is formed.
This precipitate is insoluble and separates out of the solution.
So, the correction answer is AgCl(silver chloride).
The position of the solids in order from Lowest melting point to highest melting point are:
- Non-polar molecular - polar molecular -ionic solids - Covalent network.
<h3>What is meant by melting of point?</h3>
The melting point is a term that is defined as the point at which any given materials is altered from a solid to a liquid.
Note that the temperature at which solid is altered its said state to liquid at atmospheric pressure is seen as the melting point of that given liquid.
Hence, The position of the solids in order from Lowest melting point to highest melting point are:
- Non-polar molecular - polar molecular -ionic solids - Covalent network.
