Both compounds dissociate into their constituent elements without electron transfer.

The iron(III) oxide is reduced to iron metal, and carbon monoxide is oxidized to carbon dioxide.

Iron(III) oxide is oxidized further as carbon monoxide reduces into elemental carbon.

The iron(III) oxide remains unchanged while carbon monoxide polymerizes into larger molecules.

Does incorporating different organic substrate types into anaerobic digesters modify biogas production profiles methane versus carbon dioxide ratios therein?

Can modification electronegativity differences metals used electrodes significantly determine overall power generation microbial fuel cells(MFCs)?

How might certain ions preferentially pass through membrane channels as influenced by localized proton gradients established via membrane-bound respiratory complexes I-IV activities?

What role does varying molarity play regarding osmotic pressures produced across synthetic semi-permeable membranes devoid any active transport processes?
