For the arsenic one I wrote that the molecular arrangements caused the difference, is that right?

For the increased mass of Cu I wrote that as the electrons flow the cu ions become atoms and then the ions in the solution migrate to the cu electrode increasing its mass.

Was the question regarding H20(gg) -> H20 (l) 11300 or something like that for the energy? And I wrote entropy decreases because it goes from gas to liquid, liquid's molecules are less scattered, less disorder, less entropy, or something like that.

That question with density mass or solubility, was just density and solubility, right?

The question with the hair, hand, and ice, involved all 3, hand to air and ice, and air to ice?
reuben, its the one with the cl and br.
