Depict the hydrogen bonding between two ammonia molecules and between one ammonia molecule and one water molecule?

Ammonia NH3 , have a severe electron density on the nitrogen atom (unshared electrons) so it truly is a exceptionally electron donor , whilst water and ammonia mixed NH4+ ion , OH- frormed in accordance to the donation of electrons of ammonia to the proton of water , and dative bond formed .

Hydrogen bondings are shown below.

Explanation:

Hydrogen bonding takes place between an electronegative atom (O, N and F) and H atom attached to those electronegative atoms (O, N and F). Lone pairs on electronegative atoms are involved in formation of hydrogen bond.

Electronegative atom of a molecule which donates it's lone pair to form hydrogen bonding is called hydrogen bond donor. And the other molecule whose H atom is involved in hydrogen bonding is called hydrogen bond acceptor.

Hydrogen bond is a kind of bond whose strength is an intermediate to ionic and covalent bond.

Hydrogen bonding is represented as dash lines.

Hydrogen bonding between ammonia molecules and between ammonia and water molecule has been shown below.

Its the second one nonmetals are moldable and easily shaped 

It would be true sodium reacts with water in a violent way
