Chemical properties of each elemt are determined by the elemts electroic configuration, and particulary by its outermost valence electrons. In addition, the total number of electron shells an atom determines which period it belongs to
Electrons are able to "move" around the atom in set energy states in different orbitals, because the electrons "move" so fast around the nucleus where they are is just represented with an area of probability since their location and velocity cannot be measured with certainty. Protons and Neutrons are packed tightly in the nucleus held together by the strong nuclear force so they are not able to freely move.
Answer:
From the diagram, the water is being boiled. This process vaporises the water in the vessel leaving salt crystals behind.
Since the water is needed in liquid form, the cold water at the top of the set-up
condenses the vapor so it can be used.
Fe2(SO4)3.3H2O = 56*2 + 3*(32+16*4)+3*(1*2+16) = 454 g/mol
Mol =m/M = 10.5/454 = 0.023 mol
