Which of the following solutions will have the highest electrical conductivity?

a) 0.040 m (nh4)2co3b) 0.10 m libr
c) 0.07 m nai
d) 0.045 m al2(so4)3e) 0.15 m lif

d.- 0.045 M Al2(SO4)3

Explanation:

From the ionic salts that are presented, when they dissolved in water, the ions are going to be separated. From the list above, the aluminum is the metal that posses the highest electrical conductivity.

The second ion that can conduct electrical charge is the sodium. This ability is due to the atomic structure, the electrons are easy to be be apart from the aluminum that other metals.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
