I think sand is just glass and other stuff
Answer:
Explanation:
Given that:
The mass of sodium crystal = 4.14 g
As a result, the number of atoms in the sodium crystal is:
= 1.084 × 10²³ atoms
In the valence orbital of the sodium atom, there is just one electron.
As a result, the number of molecular orbitals produced by these atoms is= 1.084 × 10²³ molecular orbital
Because valence bands are created from occupied molecular orbitals, the number of valence bands created from the aforementioned molecular orbitals is:
= 5.420 × 10²² orbitals.
Answer:
ortho-hydroxy acetophenone form intramolecular hydrogen bonding. On the other hand, para-hydroxy acetophenone forms intermolecular hydrogen bonding.
Explanation:
Hydrogen bonding:-
- Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
- Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.
The bonding can be intramolecular and intermolecular. ortho-hydroxy acetophenone can form intramolecular hydrogen bonding which means that hydrogen bonding exist within the same molecule. On the other hand, para-hydroxy acetophenone forms intermolecular hydrogen bonding in which the bonding is in between the different molecules.<u> Hence, more amount of energy is required to melt these molecules in case of para-hydroxy acetophenone. </u>
