The iron in blood exists in bound form (it forms part of haemoglobin), so the oxygen cannot oxidise it and form rust.
The chemical symbol for iron is Fe and for oxygen is O.
The byproducts of cellular respiration are carbon dioxide and water. These byproducts are produced as a result of the breakdown of glucose in the presence of oxygen to generate energy in the form of ATP.
all the options given are chemical changes.
Rust is a chemical reaction to the surfaces of iron or steel becoming damp. When iron or steel get wet, the surface reacts with oxygen in the air and the water (usually rainfall) causing the metal to rust.
Anaerobes.

The rusting of the iron is a slow oxidation. In this slow oxidation matter links up with oxygen very slowly. There is no flame. THE HEAT THAT IS GIVEN OFF IS SO SLIGHT THAT IT CANNOT BE FELT.
we call N2O a nitrus oxide coz we combined two atoms of nitrogen and one atom of oxygen. remember that oxide is came from oxygen and nitrus is came from nitrogen.the given is N2O,it meanstwo atoms are given.

Oxygen is the gas given out by green plants during photosynthesis.
The homonym of presence is presents, which refers to gifts given on special occasions.
the blood is given oxygen as it passes next to the alveoli in the lungs. The process by which the blood gets oxygen is called diffusion
The name given to the inside of your hand is called the palm. :)
