Write the chemical equations showing the dissolution of sodium chloride, naphthalene C10H8, potassium phosphate, and calcium chloride. The first one has been done for you as an example.
NaCl H2O Na+ + Cl-
C10H8+H20--->10C-4 +8h+
K3PO4+H2O--->(3K+)+1PO4-3
CaCl2+H2O--->Ca(2+)+2Cl-

If an equal molar amount of each solute in the above was dissolved in 100 kg of water, which solute would cause the largest change in temperature? Explain your answer.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
