Yes. Just connect the black wire to one of the poles and the white wire to the white bus bar. Make sure the wire you use is sized for the ampere rating of the breaker. 15 A = 14 AWG, 20 A = 12 AWG and 30 A = 10 AWG.
No. Three phase power must be supplied to you from your electric utility, or you can get a phase convertor.
To get three phase 220v from 440 you need to have a 440 to 220 three phase transformer installed. Cost is not prohibitive most depending on what KV is required are in the $500.00 range.
On the North American electrical system, no. A single pole breaker feeds a load to the neutral wire with 120 volts. It takes two breakers to obtain a 240 volt potential.
U.S. 240 VAC breakers are always double pole since they are protecting two legs of the circuit.
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
If it was two wires under one screw on a single-pole breaker, that would not be proper, and most probably against electrical code.If it was two wires, each under their own screw on a double-pole breaker, then that would be a 220 volt circuit; each wire going to its own "leg" of the breaker panel.
One breaker in the North American electrical system will supply 110 volts. Two adjacent tied breakers will produce 220 volts.
No, A double pole breaker is going to give you 220 volts. 220 Volts is too much voltage for a 110 Volt outlet to handle. == Answer== Better to pull the duplex 30a and install to single-pole 20a breakers...if one kicks out, you will know which side the problem's on. And there's no problem with running a 20a circuit over 10awg wire.

Two single-pole 30 amp breakers tied together make a two-pole 30 amp breaker. From this you can power a device that requires 220-240 volts, typically.
In North America a two pole breaker will be used in the distribution panel for a supply of 240 volts for a 240 volt load.

No. If your AC is currently running on a 30 amp 2 pole breaker, then it is a 220 volt unit. You cannot substitute one 60 amp single pole breaker as you'll only be supplying 110 volts and the AC unit won't work. In fact you could damage it.

A 4500 watt element will work on a 20 amp breaker if it operates at 220 volts or less. It will simply trip the breaker if the load is greater than 20 amps at 220 volts.
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
Answer for USA, Canada and countries running a 60 Hertz supply service.It is possible to have a dryer that is built to work on a 30 amp single pole breaker but not likely. The most common dryers sold in the U.S. are designed to run on a double pole 220 volts 30 amp circuit. When ever installing electrical equipment it is always necessary to read the manufactures design specifications. They should be clearly marked on the tag with the "UL" seal.
