g Solid copper sulfide and silver nitrate react to form copper (II) nitrate and solid silver sulfide. Write a balanced chemical equation that describes the reaction. Identify the oxidation number of each element in the reaction as well as the physical state of each compound. You do not need to include the total contribution of charge. Is this reaction a redox reaction or a non-redox reaction

It is a non-redox reaction.

Explanation:

Hello.

In this case, when solid copper sulfate and aqueous silver nitrate react to form solid silver sulfide and aqueous solid silver sulfide we can write:

In which the oxidation states are assigned based on the periodic table and taking into account that the left-handed ion is positively charged whereas the right-handed one is negatively charged:

Thus, since the oxidation states do not change from reactants to products, we infer this is a non-redox reaction.

Best regards!

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: )
