Both can be changed by linking the sulfur to oxygen molecules.

Micropores in the sack passed oxygen molecules through to the interior.

When seen from the air (plan view) it resembles the shape of an oxygen molecule.

It felt like all the oxygen molecules had been burned out of the air.

That's enough to allow oxygen molecules to pass through the field.

The last destination for an electron along this chain is an oxygen molecule.

Effects are: an inability for blood to release stored oxygen molecules to the body, resulting in death.

The oxygen molecules leave the water more often.

This is due to the unusual electronic structure of the oxygen molecule.

Flambé can manipulate oxygen molecules to increase a fire's size and temperature.
