i always thought that you would suffocate like when theres something stuck in your throat, like you cant breathe in air
can you breathe in when theres no oxygen? like can you take a breathe but it just wouldnt feel right because theres no oxygen? can you fill your lungs up with air thats not oxygen?

So... a couple of things...
1. If you're in space (say, an astronaut removes his/her helmet) - the air is sucked out of the suit, *and* his/her lungs. There's other problems that go on (which result in death), but for now, the astronaut tries to draw in a breath. His/her diaphragm distends, and, if there were air around them, the lungs would be pulling in atmosphere. But in space, there's nothing to pull in. The muscles would work, but to no effect. The astronaut dies, because there's no atmosphere with oxygen to sustain the chemical reactions in his/her body...
2. Say you're on... Venus... no, Titan. (Titan is closer to Earth's atmospheric pressure). Again, the astronaut standing on the surface removes his/her helmet, and breathes in. Now, their lungs fill with the gases of the atmosphere - but it's not oxygen. It's nitrogen and methane. Again, the astronaut dies, but now it's because the oxygen they need isn't in the atmosphere they're breathing in. Think of someone locked in the trunk of a car - eventually, the usuable oxygen is consumed, and it's replaced with Carbon dioxide... the person locked inside will die, because there's not enough free oxygen to sustain their body.

you can't breathe in a vacuum(space) much like it's impossible to drink from an empty glass.
when you breathe you lower the air pressure in your lungs causing air to flow in as it moves from high to low pressure. in a vacuum the pressure is 0, and regardless of how hard you try the pressure inside of your lungs will always be higher than that.
so in space you'd violently exhale, and you can still expand your lungs making a inhale motions exept you wouldn't inhale anything.

They use space helmets that produce oxygen for you.

no you cant because there is nothing to breath.

well.. imagine a very strong vacuum cleaner shoved in your mouth. since there is nothing all the air in you will leave you
