An ice sculpture melts into a puddle of water. what is true of this reaction? it is spontaneous. energy had to be added to the system for the reaction to occur. the reaction happens faster if the ice sculpture is large. no work is done in this 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: )
