oxygen i s colorless gas because it does not appear in the visible region of uv visible spectroscopy
oxygen is needed for fuel to burn
Oxygen
For all animals: oxygen.
hi me know the anser but I is not telling u!!
hydrogen

By smoking you reduce the amount of oxygen carried in the bloodstream because one of the gases generated by the burning of the tobacco is carbon monoxide. This gas combines with the haemoglobin in the red blood cells in the same way that oxygen does. But when this happens the oxygen-carrying power is obviously reduced. This is why carbon monoxide is a poison.
Oxygen
It is the very unstable gas called ozone.
Oxygen is used by cells.
Oxygen. It must be present along with fuel and heat for combustion or burning. It combines with elemental iron (Fe) to form iron oxide or rust. Oxygen and moisture are necessary for the germination of seeds.
Natural gas is a fossil fuel (mostly). If it is methane CH4 it burns with oxygen to produce CO2 and H2O (carbon dioxide and water): Each carbon atom combines with two oxygen atoms, while every pair of hydrogen atoms combine with a third oxygen atom. Every pound of fuel burned creates 2¾ pounds of carbon dioxide.
Because they do.
All cells need Oxygen.
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
