D because these are the biggest particles, and are therefore, the most dense.

There is an unstable ratio of protons and neutrons. Because protons are positively charged but neutrons have no charge, an increase in the number of protons means there needs to be an increase in the number of neutrons to "bind" the nucleus together. This is because like charges repel, so the protons will repel each other, and if there aren't enough neutrons to act as "glue" to hold the nucleus together, the nucleus will break apart.
2(CH3)2O3 + 2H2O ---> 4 CH3COOH is the balanced equation.
B.) Valence Electrons. The nucleus of the valence electrons attracts and pulls atoms together.
