Double Replacement

The double replacements in this lab was the CuO+2HCl=CuCl+H2O and 3CuCl+2Na3PO4=Cu3(PO4)2+6NaCl. These reactions occur when Cu is bonded with another chemical and added to two other chemicals. The driving force of the first double replacement is a physical reaction which changes the physical apperance of the chemical due to the heat that is add to the chemical when it is place on the hot plate. The second equation is a chemical reaction due to the mixture of the CuCl and the H2SO4 forming the chemical reaction.
