b) NiCl2

c) CoCl2

Explanation:

The formula for the given complexes are as follows -

a) Chloro Complexes of the Copper(II) - CuCl2

b) Nickel(II) Complexes of the Copper(II) - NiCl2

c) Cobalt(II) Complexes of the Copper(II) - CoCl2

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

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: )
