Which of the following statements is not true? question 4 options: when atoms have similar electronegativities, electrons are shared equally when electrons are shared equally, the molecule is called a nonpolar molecule. when two atoms have different electronegativities, the electrons in the bond are not share all of the above statements are true.

All of the above statements are true.

Explanation:

When atoms have similar electronegativities, electrons are shared equally. TRUE. Electronegativity represents the "strength" that an atom has to attract electrons. If both atoms have similar strengths, the electrons will be shared equally in a covalent bond.

When electrons are shared equally, the molecule is called a nonpolar molecule. TRUE. Polarity means that there are zones with positive and negative density charges. This happens when electrons are not shared equally (different electronegativities) and the area where electrons spend more time is more negative. If electrons are shared equally, then the molecule is nonpolar.

When two atoms have different electronegativities, the electrons in the bond are not shared. TRUE. The atom with the higher electronegativity gains electrons and the atom with the lower electronegativity loses electrons. This is an ionic bond and electrons are not shared.

All of the above statements are true.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

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).
