How many oxygen molecules are produced when 89.5 g of mercury (II) oxide are allowed to decompose
according to the following equation: 2Hgo > 2Hg + O2​

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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: )
