Activity 3 1-19-11 Crystal Structures

Show crystal structures for NaCl (sodium chloride)and CaCO3 (calcium carbonate). what is the melting point for these two materials.
NaCl (sodium chloride)
  • melting point = 1474*F
  • to melt an ionic material, you have to break the bonds
  • known as salt
  • most responsible for salinity of the ocean


CaCO3 (calcium chloride)
  • melting point = 1517*F
  • found in rocks in all parts of the world
  • used in agricultural lime and medicinally as a supplement
