Q2. Use your reactivity series to work out whether or not these displacement reactions would occur or not. Write true or false after each equation.
a)
Lead chloride + zinc → zinc chloride + lead
b) Tin bromide + lead → lead bromide + tin
c) Aluminium oxide + magnesium → magnesium oxide + aluminium
d) Copper chloride + zinc → zinc chloride + copper
e) 2 AlCl3 + 3 Ca → 3 CaCl2 + 2 AI
f)
2 FeCl3 + 3 Pb → 3 PbCl2 + Fe
B)
SnBr4 + 4 Na → 4 NaBr + Sn

dipole moments occur when there is a separation of charge. they can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. the dipole moment is a measure of the polarity of the molecule.

explanation:

in inorganic chemistry -dipole moment ( μ ) is the measure of net molecular polarity, which is the magnitude of the charge q at either end of the molecular dipole times the distance r between the charges. μ = q × r.
