Explain how the need for energy is the driving force of the oxygen cycle. Yet again earth science

Engery is the driving force of the oxygen cycle is photosynthesis itself, which is responsible for the creation and maintenance of earth's atmosphere.Plants are able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen.

Energy is the main force of the oxygen cycle and not to mention also photosynthesis, which is responsible for the creation of the earth's atmosphere. This would also mean that plants are the main focus of the Oxygen cycle and energy is needed to make plants. So without energy, no plants would exist!  Not to mention the oxygen cycle wouldn't work without energy.  Plants are also able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen.

Hope this helps! :)

Explanation:

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).

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: )
