Yes no problem the transformer should run a little cooler as well.
you can't
No, 120 v is not enough.
More than likely yes it will work just fine.
yes.
Yes, no problem.
nothing
No! Normally not, the recistance in the windings is to hig on 60Hz and the pump motor has not power enough to work propelly. This happened to myself when I connected my Whirpool AWE 7519 to 230V 60Hz. Europian model for 50Hz.
No
Yes, using a 220v-60hz microwave in Australia is fine. The voltage of alternating current supplied to homes in Australia is 220v. The frequency of the voltage is 50hz.
Frequency doesn't come into it for normal electrical devices, as long as the voltage matches it will be fine. 50/60hz differences only really affect display equipment.
No. For more information see the answers to the Related Questions shown below.
Depending on the device, it may or may not work. And if it works, it won't work properly. A 60Hz devices needs 60 cycle current, not 50.
