Similarity between dipole-dipole and dispersion forces

London dispersion forces occur between nonpolar molecules and are extremely weak.
Dipole-dipole forces are between polar molecules, and since polar molecules have slight charges, their force is more similar to ions, giving them a moderately strong bond. Hydrogen bonds occur when hydrogen is directly bonded to Flourine, Nitrogen, or Oxygen. Because of the extreme polarity if these molecules (e.g. water), hydrogen bonds are the strongest dipole-dipole bonds.
Ionic crystallization packs ions into a crystal, and those are extrao

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
