Me pueden ayudar a representar este enlace molecular : HCN

Three valid representations are:

Each dot represents one electron.

Explanation:

HCN is a linear compund, with a triple bond between carbon and nitrogen:

CN⁻ is an anion with a triple bond between carbon and nitrogen, whose representation is:

The negative charge on the structure is due to the fact that the C atom has 5 electrons, instead of 4 in the valence shell, meaning that it has one extra negative charge.

That structure is also represented with:

When it bonds to a hydrogen atom it is: H-C≡N

Three valid representations for HCN are:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
