Based on the image above, which of the following is true? A. Mass was lost in this chemical reaction because the atoms in the reactants are smaller than the atoms in the products. B. Mass could have either been gained or lost during this chemical reaction because atoms always change mass when they react. C. Mass was gained in this chemical reaction because there are more atoms in the products than there were in the reactants. D. Mass was conserved in this chemical reaction because the same atoms are present in both the products and the reactants.

true

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

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: )
