Water can be a solid
liquid, or gas in Earth's water cycle.
Identify two processes in the water cycle
where water changes from one state
to another state and then back to the
original state.

Condensation and Evaporation

Explanation:

Condensation is the process of water changing from its gas to liquid state

Evaporation is the process of water changing from its liquid to gas state

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: )
