Calculate the pOH of a 7.68x10-7 M HCl solution.

pOH = (round to 3 sig figs)

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).

a polar bond is formed when electrons are shared unevenly between atoms

the answers would be

the first one and the second one
