How do you separate the carbon element and oxygen in carbon dioxide?

Answer 1

Carbon is solid (black powder, grey graphite or brilliant diamond) and methane is a (very light, explosive) gas. There is no need to separate, they alredy are! and do NOT dissolve in each other, so they'll stay separated as well.

Answer 2

One way to separate carbon and oxygen in carbon dioxide is through a process called electrolysis, which involves passing an electric current through the compound to break it down into its constituent elements. Another method is high-temperature thermal decomposition, where carbon dioxide is heated to very high temperatures, causing it to decompose into carbon and oxygen.

Answer 3

These two liquid compounds separate into two separate phases spontaneously!

Answer 4

By filtering

Answer 5

with heat
