Is there a way to electronically split CO2
I want a strait answer no junk about it being to hard

You are correct CO2 ain't hard at all. It's a gas. This is in the easy realm of particle physics. Use a simple cyclotron (patented in 1934 by Lawrence) just two metal D plates and an alternating voltage will accelerate a particle up to enough speed to split the molecule of your choice.
Are you collecting carbon?

Yea, I meant that CO2 was to hard (requires to much energy) to separate practically.
I actually just wan't to find out if there is a way to easily split CO2 electronically for say a space shuttle or space station, do they do this. I would then try to find a way to turn the carbon into something useful.

Could I split CO2 with hydrogen relatively easily ? Under what conditions ?

Yes, I have searched it, I always find the answers like photosynthesis, extreme heat (but you have to separate at high temp or they will recombine), or that it requires to much energy to be any benefit.

And what do you conclude from that?

That not very many people have the knowledge of this. I know you can input energy without having to separate the two while the energy is applied I just didn't know how to do it. I have seen machines that do it, but nobody says how and now I have my answer so I conclude. If you at first you don't succeed try on your own again.

OK, take two platinum electrodes, and preheat a bath of calcium carbonate to ~550 C. Bubble the gas into the carbonate.

Failing that, solid, gadolinium doped cerium oxide works too.

What will happen, will it output separate carbon and oxygen gas or will one be left inside the calcium carbonate? They won't recombine will they?

Also what does "Failing that, solid, gadolinium doped cerium oxide works too. " mean.

There is no such thing as carbon gas, until you reach many thousand Kelvins. basically, not all the CO2 is split.

I meant carbon, and gaseous oxygen, but this method doesn't really work that well
