I recently purchased an Eflite brushless motor that came with some Xoar 22x10 props. One of them is still in the package and it has a sticker on it that says "electric". I am sure there is some difference but why can't I use this prop on my 45cc gas engine? I looks to be sufficient but I know looks can be deceiving...

Electric props tend to be thinner and therefore not strong enough to withstand higher RPM or vibration.

Thanks, that's what I needed to hear.
