Impedance can be resistance or reactance. Reactance further subdivides into inductance or capacitance. You only get reactance with alternating current.
If you have an Inductor with the same reactance as a Capacitor, you will have a 'resistive load'.
An inductive load could be motor, transformer etc......anything with a winding or coil.
A capacitive load is basically....a capacitor! There isn't many 'capacitve appliances'. Capacitors are often used to cancel out inductive loads. The most common is within a flourescent fitting.
remember impedance depends on frequency and is only really meaningfull in a steady state AC system.
specifically if you have an inductance and capacitance wired in paralell whilst the reactance will cancel at mains frequency you will still have the transiant behaviour of the capacitor and the inductor which can be nasty for switching.(capacitors cause a current surge on switch-on inductors a voltage surge on switch-off)
