Answer:
H2
Explanation:
CO2 + H2 → CO + H2O
↓ (-2). 0. (+2 )(-2). (+1)(-2)
↓ ·2 (+2)
+4 (-4)
Write down the oxidation number under each element, each molecule should equal 0 unless there is a charge shown.
Oxygen, always has an oxidation number of -2 unless in a peroxide.
Hydrogen, is -1 with metals,+1 with non-metals. Hydrogen loves non-metals!
H2 is zero because any standalone element has an oxidation number of zero
What is being oxidized? Whatever is being oxidized, loses electrons and becomes more positive, it will be a whole molecule, not just an element. In this case, the H in H2 goes from 0 to (+1) so it is the oxidized molecule.
The Inclosure Acts, which use an old or formal spelling of the word now usually spelt "enclosure", cover enclosure of open fields and common land in England and Wales, creating legal property rights to land previously held in common.

When a solid turns to gas it is called sublimation, and when a gas turns into a liquid it is called deposition
